    I don't think the Wattage on the Asus is necessarily lower... if anything it would be quite similar (unless you're talking about the 4800HS or 4900HS parts which have 35W TDP - but that makes it a bit of an unfair comparison because Asus has exclusivity rights to HS parts for 6 months).

    The 5600M should be pulling 80-100W tops... which makes it more or less in line with refresh RTX 2060 90W TDP (and given the 5600M specs, it should perform about 10% below the desktop version).
    But current benchmarks DO say the 5600M in DELL does perform between 2060 and 2070 Max-q in various titles... in others its more along the lines of 1660Ti or up to 2060 - as I said, these performance numbers are a bit skewed at the moment given DELL's history with cooling.

    Plus, the 4800H has a TDP of 45W. Even if you factor in that the CPU can go up to 60-65W for short bursts, that means the cooling assembly needs to be able to remove/dissipate about 165W effectively if both CPU and GPU are stressed to the maximum.

    This wattage and heat output doesn't seem THAT much for a 15" unit (though DELL seems to use a shared heatsink with only 3 cooling pipes - you'd think they'd use 3 pipes for the APU and 3 for the GPU - or at least DOUBLE compared to what they have right now).

    Previous 15" units used similar or higher wattage than that and they were fine.
    DELL just seems to have a bad track record with cooling and thermal paste application. For all we know, the cooling assembly is 'CAPABLE' of efficiently cooling that hw, but not if the thermal paste has been incorrectly applied (or they used very bad stuff with low-quality application).

    Plus, there's the fact that undervolting was almost always necessary on DELL units with Intel and NV (which doesn't paint a nice picture of the OEM to go unprepared like that - but it would also make our work more difficult since AMD doesn't have an official support for undervolting mobile chips that I know of - as for their GPU being undervoltable... possibly... but I don't know).

    Yes. I'm specifically pointing to the HS variant CPUs used in the Zephyrus range... Exclusive to Asus.

    Do the 35W processors have lower idle TDP? Either way I am guessing they probably would only be used in the slimmer chassis, which the G5 SE is not.

    I wonder if the Dell Power Companion works with it?

    TDP in idle condition? What's the chance of one to turn on their newly acquired DELL G5SE and then leave it on to assess it's idle time achievement against workable hour?
    Let's say the IDLE TDP of HS and non-HS CPU is the same, HS CPU is certainly going to last longer than it's non-HS H-twins of the same "number" identity, and both going to be beaten by their U siblings... Should there be a 4600*/4800*-U, 4600/4800-H/HS will have to be shuned by folks looking for long distance briskwalker.
    *(if there's such identification model number in AMD inventory...)

    DELL Power Companion... Hmmm... After a long period of employing INTEL CPUs into their products, i seriously doubt that DPC will work with AMD CPUs. Since there may not be a need for that little ignorable perfection of DPC for that little amount of AMD products sold in the market.

    Seems like new paste helped a bit for cpu speed and gpu temps. I bet Kryonaut would get you further. Have you tried undervolting GPU? With afterburner? That will probably improve thermals and cpu speed if possible due to shared heatpipes.

    Possibly, but why is the CPU still going to 101 degrees C after repaste?
    Sigh... DELL probably ended up putting a dingy cooling assembly.

    I think this is a fundamental DELL issue with cooling capacity. At this point, it seems the repaste did help, but not by much. What I do think would probably be more beneficial is undervolting the CPU (I just don't know if its possible with Renoir) and possibly the GPU if it can be managed (though its temperatures do seem pretty ok).

    Do some retesting with this repaste to see if some CPU/GPU results improved.

    Maybe ryzencontroller will be compatible and you can lower tdp, that might improve temps quite a bit. All core turbo is probably around 3.5GHz so as long as temp is not over 100C or tdp is exceded it will increase speed instead of lowering temp. Undervolt and maybe slight downclock of gpu would probably help a lot.

    Usually for most DELL units with Intel/NV worked was undervolt and re-paste. Undervolt though was a lot more effective as it managed to bring down temps by 15 degrees Celsius.
    But I continue to maintain that DELL bummed out on the cooling assembly... should have given this unit better cooling.

    I think the bigh thing is that is where dell has the thermal cap set and it will boost wattage/speed till it gets to that temp.

    I will retest thermals in a day or 2 once it burns in the paste but here is some cringe worthy pictures.
    Before:

    After: obviously I applied thermal paste but didn't remember to take a pic of that. and was no where near the quantity of dells thou...

    This is the system sustaining ~100% CPU and GPU usage @ ~90% for 9 hrs. straight...i am happy with the temps and thermals personally you have to remember you wont be pushing 16 threads this hard running any games. this is the absolute worst case scenario i am pushing it with currently and helping Fight COVID at the same time :) and does appear the temps have dropped but so has the cpu speed. but that could be attributed to my office being in the western sun and 8F higher than it was this morning...82 VS 74...

    Yeah, games never stress these kinds of CPU 100% (heck they don't do that on my 2700 or Vega 56)... my concern about temperatures and sustained performance with Zen 2 laptops lie in productivity (which I do quite a lot of using 3d studio Max, etc. - which tend to stress all of my 16 cores to the max).

    So, if I were to leave the system running over-night to render something, I wouldn't want temperatures anywhere NEAR 100 degrees C. 80-85 degrees perhaps (as the absolute maximum).
    Fortunately, I don't have to worry about that on my Helios 500 (whose maxed out 16 threads temps don't appear to exceed 77 degrees Celsius - and its not very loud in the process).

    An extra cooler might be good option to try out if you're willing to spend extra money.

    There IS one more course of avenue which you hadn't necessarily considered.
    Liquid Metal.
    When the temperatures are in the range of 100 degrees Celsius, LM seems like the only viable option that might be more effective in keeping them below this value (it may not drop them to 85 degrees Celsius on the CPU, but it may be possible to drop them to 90 degrees Celsius - but who knows) ... however, I wouldn't want you to risk the system on satisfying our curiosity (even though you could minimize/prevent spillage with foam dam barriers pretty easily on both the CPU and GPU).

    If you're happy with the current temps, then that's good for me. Retest the system with Noctua thermal paste as is and compare the results for us (though for the life of me, why couldn't DELL put more effort into CPU cooling and have its max. temps not go over what 5600M is putting out when its maxed out).

    Oh and, are you using latest drivers?
    Any issues with Freesync, just remember to use CRU software to re-enable it if you're doing a clean install.

    Yes running Latest Driver From AMD.com the dell driver doesn't include the AMD control panel which i like having. and the latest 1.2 bios. i would expect them to apply fixes etc over the next month or 2. once the lower cas latency jdec 3200Mhz ram comes out i will upgrade to 32GB not going to play with the memory that requires xmp as there is no xmp option in the bios that i see.
    the screens motion looks amazing compared to my XPS i will be playing aroung in KSP some too gotta see what happens when i do stupid stuff :)

    ALSO i have tested it with my WD-15 that i got when i got my XPS(was too cheap to buy the TB version and wanted to make sure it would work with future AMD systems) and USB and dual video work fine for me over USBC so i am exstatic about that. Just have to provide power it WILL NOT accept power over usbc from my XPS PSU or the dock.

    Correct me if I'm wrong, but even if you do get XMP based RAM that runs at 3200MhZ and has CL15/16 latencies, wouldn't the RAM run at those defaults anyway since its supposed to be base spec for it?

    If not, HOW do you make a distinction between which RAM has higher JDEC? Its not exactly advertised in the RAM description.

    More to the point, WHY aren't laptop OEM's including XMP profiles into the BIOS on AMD motherboards by default?
    The same thing happened with my Acer Helios 500, and for the life of me, I cannot understand WHY would Acer limit this monster's RAM to 2400 MhZ if all 4 RAM slots are occupied? Its a B450 desktop based motherboard modified for a laptop, so I fairly doubt there's a physical limitation of the RAM slot since practically all B450 mobo's with more than 2 RAM slots easily run quad ram sticks at their native speeds of say 3200MhZ and low latencies.

    Oh and, would you consider at some point to using Liquid Metal and foam barriers to test the temperatures and performance of the DELL unit?

    I'm actually discouraged that no other laptop (besides DELL G5 15 SE and MSI Bravo 17) won't be using SmarShift technology. Since that feature requires both AMD CPU and dGPU to run (and is baked into Renoir on a hw level), it also implies no other OEM will be using AMD dGPU's like 5600m or 5700m this year (AMD rep. confirmed there will be no other laptops with SmarShift tech until 2021).

    According to this:
    https://www.tomshardware.com/uk/news/amd-smartshift-dell-g5-15-se-available

    "SmartShift requires no user input and no software, and AMD claims that feature gives "gamers up to 14% more performance averaged across select games."

    This actually confirms its a hw feature that is always on if the system has a Renoir APU and AMD dGPU... and that apparently no other laptop will have it.

    100 laptop designs using Renoir, and if I'm correct, only Dell and MSI have Renoir APU and a Navi dGPU inside for the entire 2020.

    I don't understand why would AMD make both 5600m and 5700m only for DELL to use 5600m and 5700m to go completely unused.

    @chris_compson why fold on the CPU with your laptop? You'll likely produce more PPD folding on the GPU only. I don't even do CPU folding on my 3900x, it's just not worth it in terms of heat/energy use/taking cycles away from the GPU folding aspect.

    Speaking of Folding@Home... I've been running the COVID-19 project for over 2 hrs now on both CPU and GPU, and I have to say I'm impressed with the temperatures.
    Initially, the CPU temp climbed (slowly) to 81 degrees C, however, after propping up the front of the laptop a bit on my stand, it quickly dropped to below 75 degrees C (Averaging about 72.7 or within that ballpark ever since).

    The GPU is at insanely low temps... and you can hear the fans, but not on a level that would be considered 'disruptive'. I can easily listen to audio on the laptop speakers like this without the fans getting in the way - during actual gaming the fans are even less audible.

    Cannot say what the exact db rating is, but definitely under 50... maybe 45?

    I uploaded some screen grabs for comparison.
    Not sure how Folding@Home scores work to be honest as this is my first instance of using it

    Not a bad idea, though it might be better to limit the CPU to 3GHz instead... less of a cap, but probably same benefits... or he could try first with 3 and then drop to 2.9 if the benefit is better.

    I don't think SmartShift is to blame here at all (if that's what you mentioned)... its DELL's cooling assembly which isn't adequate for the 4800H (and is probably limiting the 5600M).

    But why did temps drop to 70-80C when ysing external monitor? Something is not right...

    The mod I mention can make cpu run base clock, base clock is 2.9 so thats why :)

    You have to keep in mind that this occurred on a completely different laptop (Asus).
    Whereas this thread is dedicated to the DELL.
    The conditions are not the same, especially because SmartShift isn't working on the Asus (because it doesn't have an AMD dGPU).

    As for why temperatures dropped to 70-80 degrees C with an external monitor... beats me. Could be a bug in Windows power allocation or in the way Asus manages power via BIOS (they may release a BIOS update to fix this problem if its down to that - unless of course the display is very power demanding which shifts the GPU into higher power mode for whatever reason).

    The frequency reduction could have reduced voltage for a given frequency severely.
    Say that 3.1GhZ is set by AMD to a given voltage, however, 3.0GhZ would be set to much lower voltage (and 2.9 GHZ to an even lower voltage).
    The reduction could be exponential.

    Since we don't have the ability to undervolt Zen 2 chips (yet - hopefully we will), we cannot see whether we could drop voltages on base clocks that would reflect the same change.

    I changed my mind, see sig.

    How are the temps with the 4600H?

    I know the 2x4gb isn't great, but it's cheap and I have a decade plus of Steam backlog including at least a dozen [or 2] of AAA titles too embarrassing to list. At this point I think whatever I get will split duties with a PS5 until mobile Ampere-Super/Hopper. I do plan to run Cyberpunk with it since I already preordered it.

    I decided to lean towards cheap [under $1k, incl tx if possible ...the-less-the-better] cause this is certain to be a hand-me-down to a videogamer who will be 9-10 when I give it to him. I'm also waiting to see Acer's new stuff.

    No, Steven from Ownordisown said the external monitor temp happend on this laptop, I have not mentioned Asus. When he unplugged temps skyrocketed again. Could perhaps be due to lower Hz on monitor which invoked a fps lock if v-sync was on. He also said that when total system consumption of cpu/gpu are in the 85-95W cooling keeps pace, but when total consumption rise to 115W it becomes overwhelmed and temp spikes. It could make sense if cooling system is capable of say 100W. Undervolt of gpu, run cpu at baseclpck or both might resolve the isdue, but that should dell figure out and fix, not us entusiasts.

    Ah, I did not notice that you were talking about the DELL itself.

    But now that you mention it, yes, a lower refresh rate external monitor (set to about 120Hz and 120FPS cap in the drivers) would indeed drop temperatures (because the GPU doesn't have to work so hard - this would be similar to Radeon Chill where you set a FPS limit in the drivers - although for the external monitor, if its 60HZ/60FPS, then the drivers automatically limit the GPU to that refresh rate - but I didn't know the drivers would do this themselves).

    But again, this is NOT down to SmartShift, as it only dynamically shifts existing power from CPU to GPU and vice verse depending on the task.

    How about the people try to limit FPS in drivers to 120-144Hz instead?
    Otherwise, the GPU is working harder than usual and goes possibly beyond the display's 144HZ threshold, resulting in wasted frames and more power being expended.

    Again, yes, undervolting the CPU and GPU would probably help, but as you mentioned, its not up to us to fix DELL's mistakes (DELL was supposed to integrate cooling that took into account total power consumption of both the CPU and GPU).

    @chris_compson

    I seem to have stumbled upon something 'interesting'.
    Thus far, a little software for Linux known as ZenStates was used to undervolt mobile Ryzen chips.
    It seems it exists for Windows too, so you might want to try it and see if you can undervolt the 4800H and improve those thermals and performance on it.

    You should be able to download it here:
    https://zenstates.protonrom.com/

    Also, definitely try using MSI Afterburner to unlock voltage control and Wattman (some people mentioned that Wattman was not exactly playing well and kept resetting the settings on RX 560 mobile, but would still retain the values in question - so it may be worthwhile to try and undervolt both the CPU/GPU to see if there's improvement in both thermals and performance).

    Well just stress testing the system lol yeah the GPU does fold MUCH better on its own. But its fun experimenting lol...I have noticed it seems to be feel like it runs cooler on the KB since the thermal paste swap as it was almost uncomfortable on the KB with the Dell paste. Very happy with the G5 SE,

    on a somber note im sad to hear the news my XPS15 2in1 wont be getting any more updates...another reason to stay away from a mixed environment though especially one that requires special Drivers...

    Thermals vary quite a bit. External monitor 'fixes' thermals on some games at same fps which seems strange, smartshift is a bit in beta mode still.

    Compared to A15:
    G5 runs hotter, but is 5dB lower during load.
    Vents on back are better placed than on A15. Removing cover doesn't help temps.
    With cooling pad cpu performs better than A15.
    Gpu is slightly slower.

    If I buy this I would try ryzencontroller to lower tdp, undervolt gpu, use thermal pad and repaste with kryonaut, that will probably bring down temps a lot and improve performance.

    Just got mine (4600H version) - AMA

    Few things: I got HORRIBLE screen bleed on the left edge of the screen.

    On the bottom of the laptop, at the back, it's not clipped into place properly, and no matter how much you push it together, it won't clip into place. I'm a bit worried in case this will lead to hinge failure (or is caused by the hinge).

    CPU Temps while doing nothing at all are about 45-50C. Browsing the internet it goes to around 60-65

    Haven't tried any games yet. Cinebench R20 scores 3370 with "game shift" (the G mode in Alienware CC)

    Edit: those temps are with no fan at all.

    After watching the reviews and reading all the posts here really put me off with the G5 especially the high temps, Im still hoping they'll fix it with a BIOS update as new laptops released in the market normally have problems in the first 2 months or so. Im still leaning towards the Legion 5 unless something changes...

    Short of offering people the option to return the currently bought units for refitting of the cooling assembly (and DELL also upgrading it for future units)... I'm afraid that if DELL does release a BIOS update, the only thing they could do is limit the power of both the CPU and GPU to drop temperatures (although it would be nice if they gave people voltage options for both), which will in turn drop performance further.

    DELL made a mistake with the cooling (its simply inadequate for both 4800H and 5600M - and as a result, both are losing performance and are reaching VERY high temperatures).

    I think it runs plenty cool for gaming yes if you are going to run constant loads it may run a bit warm but i think they really should lower the power limit (or let us set it in ACC(alienware command Center) some on the CPU/GPU). if i run one or the other it seems to hold its own and runs no hotter than my xps 15 2in1 under a normal load

    Legion 5 seems to have a better cooling design so far. However, we need to investigate that at which temperature when CPU reached, Lenovo settings starts to run on the fans to start air flow into the system.
    From the above quote, it seems DELL's default setting kick starts ...a little much later.

    if i'm didn't understand wrongly, most those heaty systems(Asus TUF FA506, together with DELL G5SE) reported so far draws air from bottom, while...
    [​IMG]
    (picture shown is clearly related to Legion Y740, however i believe such cooling design is ported over to the AMD system Legion 5AMD. Click for bigger picture.)
    ...cool air is drawn into the system openly from the side vents?

    The 5600m should be drawing 90-100w and an AMD rep (Azor) confirmed that in the Dell, it's actually drawing 70-80w (resulting in loss of performance).

    I realize that not all workloads will stress the gpu the same, but it's clear the GPU alone (including losingthe cpu) is loosing performance and probably cannot maintain its full boost clocks as it should due to the shared heatsink and higher temperatures.

    As I said, Dell messed up the cooling assembly resulting in loss of performance.

    5600m should technically be faster than my Vega 56 in Helios 500, but it seems to have similar or less performance (which appearss to shift rather frequently) and I can overclock mine to 2070maxq level without problems or increasing the temperatures by more than 5 degrees.

    Hm...have you seen my post about zenstates program to modifying the 4800h and using MSI afterburner to try and activate wattman in drivers?

    Ryzen controller works fine with 4800H according to some reviewers on youtube so that is good :)

    Hm... looks like no option for voltage control... but its the next best thing I suppose.
    AMD should really enable voltage regulation of Renoir in RyzenMaster and also allow the same for their mobile GPU's using Wattman.

    At the very least he might be able to reduce the 4800H boost clocks from 3.1 to 3.0 or 2.9GhZ... that could shave off decent amount of degrees from the CPU without sacrificing a lot of performance... but undervolting would be more effective.

    Now all he needs to do is also try unlocking Wattman in the mobile drivers using MSI Afterburner and fiddling with the GPU voltage (be warned that Wattman may not seem like it applied the settings, but it was reported it actually did - that and MSI Afterburner might allow direct voltage control - so he doesn't need to mess around with Wattman).

    Is anyone with the G5 Se able to confirm whether this laptop has mux switch? Freesync leads me to believe the igpu can be completely disabled, which is what I'm after.
    JarrodsTech told me he wasn't able to see any bios switch for the igpu, can anyone else confirm?

    The MSI Alpha(5500m+3750h) didn't show any bios option until advanced bios was found in secret key combo.
    Sadly the igpu being disabled caused a black screen due it not being mux.

    I think on the DELL, you can only disable the dGPU in the drivers (not sure about iGP - I think there is an option for it too).
    But I don't know whether DELL shows this option in the BIOS.

    I think I'm gonna return this.

    I don't mind high temps when I need the performance, but playing Rocket League with 15% CPU usage (4600H) and the CPU is hitting 100C

    And unlike with my 9300H there doesn't seem to be any software that allows you to undervolt, underclock or disable turbo boost.

    Can't try re-pasting because I won't be able to return it.

    Not only that, Dell Power Manager doesn't have any fan speed/performance options on it like it does with my G3 (9300H) - options such as "high performance", "quiet" and "cool" and the Alienware CC software is garbage.

    Was hoping things had changed recently with all the praise AMD is getting (and it's deserved for their performance) but the software is absolute garbage compared to Intel and Nvidia (XTU and Nvidia Control Panel)

    Oh and FreeSync doesn't work, even with beta drivers.

    ryzen controller lets you adjust boost, temp limit etc. Freesync should work with the latest drivers, several have confirmed this. Use CRU if that doesn't work.

    For me Ryzen controller didn't seem to do anything at all. I lowered the CPU TDP and applied until it said "updated" or whatever it says (not on that laptop atm) but it didn't seem to have any effect

    I've also read about CRU, but don't see how it's acceptable to think "Oh it's fine, you just need a bunch of 3rd party software products installed to actually get what you expected when buying the laptop"

    The latest drivers on AMD's website seem to have Freesync operational.
    I think the major problem until now might have been that AMD drivers delete registry marks for the display refresh rate if you do a clean install to the previous version which gets rid of Freesync.
    Plus, laptop displays don't have separate drivers which identify them like external monitors do.

    CRU is just one program... and its merely used to 're-insert' refresh rates into the registry... at which point you just need to restart the OS and Freesync will become operational (if it doesn't appear in latest drivers).

    I'm sorry to hear that Ryzen Controller didn't work.
    I'm also sorry that with 15% CPU usage, the CPU got up to 100 degrees celsius - though I don't know if this is correct (it doesn't seem right).

    You could try cleaning off the Dell thermal paste and using Kryonaut instead... or if you feel daring, use Liquid Metal with foam barriers (to prevent possible spillage).
    I think that regular thermal paste simply doesn't cut it for this unit seeing that DELL put in inadequate cooling assembly - although, we (users) shouldn't be obligated to try fix Dell's mistakes.

    Some 'experiment' this turned out to be. DELL completely botched the cooling assembly for this laptop which is completely unfit for the hw it uses.

    If you end up returning the unit, make sure to tell DELL the CPU was going up to 100 degrees C at only 15% of usage... and that in your opinion, Dell simply didn't put adequate cooling into G5 15 SE for the hardware it uses, and that as a result neither the CPU (4600H and 4800H) or the GPU are capable at operating at their fullest (even though they should be able to quite easily with low temperatures and low noise in this kind of chassis).

    Undervolting would probably be effective... but I don't know to what extent. The cooling simply seems to be too weak. Its as if it was designed for a laptop with half (or 70%) of the TDP capacity.

    Well, it seems that DELL's high temperatures are becoming a well documented issue:
    Dell G5 15 SE with AMD Ryzen 7 4800H records above 100 °C average CPU temperatures leaving the Asus TUF Gaming A15 as the better Ryzen 4000 gaming laptop option
    https://www.notebookcheck.net/Dell-...Ryzen-4000-gaming-laptop-option.469723.0.html

    Hopefully this will force DELL to admit their mistake in installing inadequate cooling, or barring that (which seems very possible) they could at least work with AMD to allow undervolting on both the CPU and GPU.
    However, it was compared to the Asus with same CPU and it was noted that 4800H in Asus was at 90 degrees Celsius during a stress test - so, DELL (or other people) cannot 'hide' behind poor excuses or limiting the TDP of the CPU or GPU (nor accusing AMD of being 'hot and power hungry').

    Lookin at how high 5600M is actually scoring in benchmarks (very close/same as rtx 2060 in Asus), its no surprise the inadequate cooling is severely limiting its (and 4800H) performance in various scenarios - which means there might be a potential for it to score even higher than that if DELL fixed the cooling.

    DELL should just admit their mistake and offer users to fix the cooling (by installing a more powerful cooling assembly as part of a 'refit') AND cooperate with AMD to allow users to undervolt both the GPU and CPU (I don't understand why AMD isn't allowing people to undervolt mobile CPU's and GPU's).

    I agree

    Im still waiting on the AMD version of the Legion 5 with the RTX 2060 to hit the market. Maybe other manufacturers will do a better job with their cooler systems on their AMD systems..

    Thus far, only Acer did AMD justice by creating Predator Helios 500 with Ryzen 2700 and Vega56 which is excessively cool and quiet when both CPU and GPU are stressed simultaneously to the max.

    No other manufacturer will be using SmartShift according to AMD's rep Azor... meaning that we won't see a full-AMD laptop again this year. Some OEM's may opt to use Intel cpu + AMD GPU such as 5600m or 5700m, but otherwise, no one will actually be pairing Renoir and Navi together it seems this year (and Dell did a very shoddy job at it by sticking this configuration into a cooling-ineffective chassis).

    This CPU hit 110C earlier while playing Rocket League (10-20% utilization, capped at 144FPS with everything set to performance)

    This is it right now

    upload_2020-6-14_3-36-13.png

    I'm doing absolutely nothing, but the fans are stuck on 100% and I can't figure out how to stop them, other than restarting.

    The problem is, we only get a 14 day window to return things and get our money back in the UK, that's not long enough to wait and see if Dell or AMD fix this with software, and given AMD's track record with horrible software, I doubt it :(

    So unfortunately I'm gonna have to send it back, and I'll probably get something with a 4600H and 1660Ti

    Dell also has thermal issues with several of their Intel-laptops so it has nothing to do with AMD.

    I've been looking this latest clip thrice...

    ...just couldn't help noticing that the temperature of the GPU generated due to clocking rate is that high when compared to Nvidia's contestants.
    And when the heat pipes were linked to one another for "better" cooling purpose...
    [​IMG]
    ...more heat had transferred to CPU side!
    I think we might need reviewers to do somekind of "Smoke Test" to determine how the air flow really help in keeping the system cool.
