Exactly See... Some go away from their computers while they are running full blast. Can they hear the fans while they are in another room? They will probaly smell the smoke before they come back in the room listening after the fan noise.

 

I do like the quick ability of Obsidian fan control. I’ve been just right clicking the tray tool icon when I was using it.

But then again, with 100% fans set at 70C you don’t ever have to do this. And once you exit to desktop your system is silent automatically.

Hey I’m new to extreme laptops ok lol.

plus I’m trying to smoke my components anyways lol.

 

I know A good advice... Look up all info before glorify a product. Not fun if a brother listened on bad advices and later brought own baby into fire

 

If you hear a bang from the other room or the smoke detector goes off you know something went wrong lol.

 

Hello!
I want to buy a laptop that comes with the P751TM1-G chassis, 9900K and RTX 2080 but I'm very worried about temps..
I do mostly computer music with large workloads and cpu-heavy soundbanks, but also a bit of video editing and gaming.
In your opinion, can this chassis be enough to cool these components for this kind of usage ? Or am I looking at +90°C and full throttle everytime ?

Thank you

 

You can easily run the 9900K, and RTX2080 in one of these systems without throttling. You may not be able to achieve ground breaking overclocks like a desktop could, but it can always push stock performance without throttling. You could even undervolt and overclock it a little.

I own a P750TM1-G it has a 8086K and a GTX1080, which is a higher wattage than the RTX2080.

So, pretty much you can squeeze desktop performance out of these smaller laptops without crazy heat. My (6) core at 4.8Ghz is running 69C in one of the most demanding games around right now. My GTX1080 is running at 74C. My processor is delidded, and my GTX1080 is running standard thermal paste with an undervolt.

The GTX1080 would run around 90C stock. But it was getting way to much voltage than it needed to run at the boost levels it was pushing in games. With a good undervolt that took a couple seconds in MSI AfterBurner and some thick laptop feet my temperatures dropped from 90C in to the mid 70’s and I am running at 1,911Mhz core clock.

After that,

Then I overclocked my Processor and undervolted it too. Heat is really not bad. I am impressed by how cool my laptop runs. Even under PRIME95 load with intel burn test running simultaneously my CPU will not throttle nor go past 89-90C and that’s at 4.8Ghz with a extremely unrealistic load. I can game at 5Ghz without the processor throttling at all.

early next year I am dropping in a 9900KS, and maybe even a RTX2080 too! That’s what is so magnificent about these incredible machines! I can actually upgrade it.


My P750TM1-G is extremely portable, I carry it to work everyday mon-fri. They are thick, and kinda heavy but extremely powerful! And I wouldn’t change a thing!

I too wanted one of these things for several years. Hardware slowly changed as the outside remained mostly unchanged on these laptops. And, I finally got mine a couple weeks ago.

 

My 751TM1 runs at around 67 CPU and 71 GPU with fans at around 70% on the curve. If i keep them at 100%, the temperatures drop to the higher 60s on the GPU and the CPU at 62-64 degrees. Rlecviewer has the assemblies I need. Maybe I can study them a bit .

 

I am using mine with 9900k and 2060 for music production.
Stresstesting the cpu will definetely throttle the cpu.
You will have to undervolt and find maximum performance without throttling.
I have all cores on 4.4 max and totally happy with its performance.
But still, stresstesting at even undervolted 4.4 will result in very high temps and result in throttling in my case. Not every cpu is the same ofcourse.
However. You will have to go crazy like hell with music production to let it throttle.
Be sure to get a 330w ? power supply. The 230w is too weak.
And get a delidded 9900k or even ks
I dont know about the 2080.

 

Thanks y'all for your detailed answers, really appreciate that !

I'm honestly new to undervolting/overclocking so I'm not planning on doing crazy things like trying to reach 5GHz 24/7, that's really not my end goal. I definitely want to find the maximum performance I can squeeze out of this laptop without damaging the components or reaching insane temps that would result in downclocking anyway.

If I can do music production with multiple instances of different plugins and VSTs without throttling or overheating, I'll be more than happy about that. That being said, most people recommend undervolting the CPU first off, so that's what I'll probably do. Then overclock it to find the sweet spot between performance and temperatures.

What kind of temps are you looking at when working on heavy music projects ? Or pretty much just at full load ? Is it sustainable now that you found your sweet spot ? Is the noise output acceptable ?
I see you have a delidded CPU which helps a lot in reducing temps, mine won't be delidded because the website I'm ordering from doesn't offer that option, so I'll stick to high quality thermal paste here.
My power supply will be a 330W.

I have to say you guys reassured me there, because a few people on the internet stated that this config would definitely overheat anyway and wouldn't be sustainable over time. So it's hard to make a choice when you have both sides of the coin at the same time haha.
I'll read a little more about your experiences with this chassis before making a final decision, but so far it's looking pretty good, seems like you all found the sweet spot and that your machine remains relatively cool in full load. That's good to hear.

 

It can overheat running one of these right out of the box with such powerful components, so there is a lot of information about this online. My GTX1080 stock was running around 90C in games and it was downclocking to around 1,698Mhz due to thermal throttle. But right out of the box it was running around 1,062MV and sometimes even more than that to the GPU. I lowered this to 0.882MV at 1,873Mhz which is a pretty good undervolt it runs in the mid 70’s now which is a huge difference. Power usage is also around 25% less too due to voltage being so much lower. I can also run 1,911mhz locked at 0.925MV and it still stays under 80C. Performance is better as it holds these boost levels 24/7 in a game if it needed to.

The processor is another important factor. You can undervolt and overclock and still drastically reduce temperatures. I did a -0.180 undervolt and overclocked my all core turbo by 500Mhz to 4.8Ghz. It usually runs in the 70’s too.

on less demanding games it’ll sit in the high 50’s to low 60’s.

idle temps sit in the lower 40’s.

This laptops is a beast. And I’m
Surprised how well it does with heat. I am squeezing desktop GTX1080 performance while running as cool as a desktop or actually even cooler than a founders edition desktop blower model. And my processor is also amazing too.

These components have a lot of voltage going to them by default which causes a lot of power and excess heat to bleed off that is just not needed. Simply finding the right undervolt will shave huge amounts off the temps. Huge amounts!

 

A very large and heavy Ableton project results in about 70degrees for the cpu. Ableton cpu meter is at 60%. But this is also depending on what u use per track. Placing a lot of vsts in one track results in higher cpu count. I believe Ableton on 90-100 cpu load will not result in overheating cpu unless it stays there for minutes. I have to check this again. But like I said, the 9900k can take an immense lot of vsts before reaching its Max. Feel free to contact me for more info.

 

I use obsidians fan control tool btw, fan noise is very quiet with the settings I use. But I always turn the speakers up anyway

 

Yeah, I am getting another Eurocom Sky X7C next month with the 9900KS and RTX 2080. I have been using my buddy's for a while to check out how the model handles the components, before I buy mine. His model has the 9900K and RTX 2080, and on Manjaro GNU/Linux I can easily OC both the processor and the GPU with a little bit of undervolting. Stresstesting the CPU will take the temps to 92c, and I capped it at 95 for testing purposes, but I didn't notice any significant throttling. Normal usage with stock settings on the CPU and GPU, rendering or gaming on ultra, I have never crossed into any kind dangerous territories at all. I think the chassis is absolutely capable of handling any laptop config possible today. Plus, Eurocom provides an upgraded in-house copper heat sink without any shared pipes. That plus thermal grizzly everywhere and a de-lidded CPU gives the Eurocom version some edge, I think.

 

Speaking of temperatures, I have two Samsung 970 EVO NVMe drives, and they are quite hot. The system drive idles at 60 C with fans at 45%. If I lower the fans to silent it heats up to 68 C idle. Turning the fans up cools it down to low 50s, but then fans are quite loud.
I have delidded 9900k and find it ironic that I have to turn up fans for the drives more than for the CPU.
Is there anything I can do to keep them cooler ? I have EKWB EK-M.2 NVMe Heatsink, but it's clearly still to hot.
I see there are some heatsinks with fans, but they need to be powered, so not sure if I can connect those in my p751.
Any suggestions ?

 

That all sounds really good to me. But you have a delidded CPU, do you think I'll manage to keep it as cool as this with a regular 9900K ?
I would love for you or anyone else to give me some tips and tools for everything related to undervolting and overclocking, so I can start looking into it and be fully prepared when I receive the laptop.

Thank you for all your answers, I feel way better now haha.

 

The 9900K is soldered so delidding will not offer such huge improvements to temperatures as previous 8th generation Intel processors would. The TIM in the 9900K is already pretty good, and delidding certainly helps but you should be ok. If you want the absolute best temps and performance possible, a 9900KS is preferable inside of a laptop because it is binned silicon and will require very little voltage to run at any given frequency. This is one of the reasons why gaming at 5Ghz on my i7 8086K is even possible inside my P750TM1-G

Where the average 8700K would need 1.412V or more sometimes to run at 5Ghz, my 8086K only needs about 1.290-1.325V to run at 5Ghz. I cannot stress test at 5Ghz as temps get to out of hand, but after I do a little more thermal tweaking I will be there. I’m so close it is crazy.

Once you get your laptop I would find the highest stable undervolt with default frequencies. Maybe start at -0.100 undervolt in XTU and test for stability and then keep knocking down 0.010v after it has proven stable. Then I’d increase the all core overclock by 100Mhz and continue to test for stability until it is unstable and either add voltage or drop frequency depending on thermal headroom. You want the CPU to stay under 95C with prime 95 preferably. And realistic usage will prove to run way cooler than that anyways.

Then work on undervolting the RTX2080. I’m not to familiar with Turing generation, so a quick google on undervolting Turning RTX2080 will reveal a lot of people undervolting it already in laptops. Max Q laptops still run the same GPU even though they have a much lower TDP so using a similar voltage at a given clock speed for reference or starting point is ok.

You will get desktop performance out of this laptop. Only some tweaking is required.

 

The same principle of editing the clock curve applies.

 

Yes my 9900k is delidded but it is not a good sample or I need to repaste. I have not repasted yet because delidding and pasting had been done by the supplier. I still assume they did a good job with that so I left it that way.

using prime95 gets my cpu way too hot so I used some real world stress tests for stability which is really important to me. My current stable undervolt is -0.80 @ 4.4

Not much help from my side but a heatsink did the trick for me.
My disk usage is probably below average so I am not having temp problems soon anyway.

Do you have a lot of diskusage for longer periods? I removed the sticker, did you?

 

Thanks for the reply, the temperatures I mention are idle, when in use it quickly goes far beyond 70 C which is the upper limit by specs.
I didn't remove the sticker, do you think it's worth doing ?

 

I will definitely be doing some tweaking, do you have any softwares to recommend for undervolting/overclocking and keeping an eye at temps ?
I'm very new to this so I want to make sure I have the right tools.
Also, I've seen you talk about unstability, what are the usual symptoms of an unstable system ? Just so I know what to look for when I'll be doing some GPU/CPU overclocking.

Thanks again : )

 

I think it is for a few degrees and in some occasions maybe more. You are not happy with both drives heat dissipation which is odd.

Some tools I use for overclocking ( I would call it underclocking because of undervolting and hard to reach cpu default clocks without throttling)
System bios (if modded by supplier)
Hwinfo tool for monitoring temps and voltages
Intel XTU for setting clocks and undervolt and even stress tests.
Realbench for stresstests

with stresstests you can check stability.
An unstable system will have system and software crashes, failing clocks, shutdowns.

having a stable system can take a lot of time if you want the most performance. Stress testing is time consuming.

In your case I would not spend a lot of time to get from lets say 4.4 to 4.5.
Stability would be more important than a Little bit more performance.

It does for sure Also a 17inch is better at cooling than a 15inch.

I agree that normal usage will not reach dangerous territories very fast.
I need to be sure however it will not throttle soon and can maintain its clocks for a long period of time.

I rather do not use Prime for that lol

 

I haven't used Realbench, does it report errors ?

The reason I'm asking is that I found ThrottleStop most useful for determining stabile undervolt.
ThrottleStop has the TS bench, which for me reported errors in matter of minutes.
From what I understand, most stress test tools rely on system crash as a sign of instability. I find them more useful for testing extreme thermals, which again I find useless for anything than synthetic benchmarks, since no real life scenario has similar loads.
System crashing can mess up your Windows, so it's not most convenient methodology.

OTOH, ThrottleStop TS bench also does the bench part by giving you a number indicating performance, but more importantly it checks for errors and I found it does so very well. If settings are way off it reports errors within seconds, if you're near it does so in few minutes.Once it reports an error, you just stop and tweak further without having to wait for something to crash.

 

RB does report failed stresstest. I am not sure if it has some kind of log to determin what went wrong.
I find TS too difficult to work with

RB can also fail in matter of minutes.
Failing within 4 hours is not good enough for me.

 

hm thats weird, im using the same heatsink on a 1TB 970 pro and my temps are in the low to mid 50s at idle (thats at 30+ C ambient, mind you).

at full load temps never reach the throttling temp of 80C, i think the highest I ever had so far was like mid 70s.

did you check and see if u can reach better temps on a different M.2 slot on your machine? also double check the coverage and fit of your hestsink and the thermal pads (used pads on both sides?)

One more thing I would like to add is that TS bench stability tests didnt agree with stability in games or programs in my case and more often than not, it would crash even when TS bench wouldnt show errors. Test them with real world situations or run P95 just to be sure.

 

Cinebench R15 is a nice tool to quickly test CPU stability, chances are if you pass it, you will also hold stability in games.

 

What I've found is that people usually use TS with Cinebench or XTU with Cinebench, I might try one of those tho combinations.
Wish me luck guys, the laptop is ordered. (I'm scared tbh hahaha)

 

Throttlestop is a great tool to assist you in fine tuning the system and see whether you are hitting any performance cap flags under load.

 

BFV is a good all around stress test.

 

I like to be 100% stable. I play Kingdom come deliverance for up to 4-5 hours on a Saturday or Sunday sometimes. But the game will run all day long usually with me taking breaks and not closing it out. And I cannot Just stop and save the game any time I want to, unless I have a Saviour schnapps potion to drink. So stability is extremely important to me. My GPU memory overclock and undervolt must be 100% stable. And my CPU must be 100% stable too. Even after hours and hours of rendering a game that constantly hammers on the CPU and GPU.

The MSI Kombustor CPU stress test with Intel burn test running together works good for me.

Nothing worse than a random crash during gameplay. It makes me dislike overclocking. And I just wanna get back to the game. So stability is extremely important.

 

It's almost impossible to be 100% sure of stability just because of the complex nature of the chip.

 

IMO it's easier on the desktop, having access to LCC and vcore, you can have a much stabler machine. However, on a laptop running offsets you might find that when you hit higher temperatures, your OC loses stability.

 

Or under sustained idle at the lower clock speeds.

 

I did the liquid metal tonight. GPU temps looking good so far. I posted some pictures in my “Laptop purchase $1,100 thread”

 

Yes, I commented on the odd paste on the vrms/vram chips.

 

Is it ok to run thermal paste directly on the GPU memory modules like that? Because it took atleast a hour to clean everything up on the video card and vrm’s around the CPU. But I also reapplied fresh Kryonaut in all the same places it was before. I reused my old thermal pads. I wanted to buy new fujipoly thermal pads. But my Amazon cart after buying copper shims, feet, gold Kapton tape, 5.5 grams Kryonaut, and conductonaut I was over budget.

 

Only viable solution is K5 PRO thermal paste. But proper pads is still a better solution.

 

Pads are used for a reason.

 

K5 Pro is a viable solution if you can't get pads that fit a specific thickness. Only downside is its thermal transfer of 5.3 W/mK. If you need high performance, there are Gelid pads at 12W/mK and FP Extreme at 17W/mK. But you also get to pay for that performance premium.

 

FP Extreme at 17W/mK is not worth the money. Too dense (less soft means less forgiving) and not even the best performing pads. High W/mk doesn't tell the whole truth. I prefer the Gelid pads... Best of both worlds.

 

I agree, Gelid pads are great. They are soft enough to have some leeway and have great performance pr dollar.

 

Thermal grizzly pads do a decent enough job too.

 

Remembers me of what Asus used in the old days in their machines, which still performs well even after 10 years.

 

They also like to cover their fans totally so cleaning is impossible and yes they would use paste as they hate anyone taking the machine apart.

 

True, not very serviceable friendly.

 

Pick the right generation and you might get access to the ram lol.

 

So, I finally found the custom watercooled heatsink for the Clevo P750/P751 laptops. It is $268 USD!

https://www.aliexpress.com/item/400...chweb0_0,searchweb201602_8,searchweb201603_52

 

Hmm, it has no microfins, just a carved channel = low surface area. And the fittings should have been quick release ones. I'd imagine the after some wear and tear on those threads it will leak.

@bennyg is the watercooling expert

 

Plus the water does not flow over the CPU directly.

 

I am going to give it a shot and see how well it works. it looks extremely beefy, and from the other photos it is running around 10-12C cooler at a minimum vs the stock heatsink. And once you add in water cooling the results are going to get better.

ive got plenty of water cooling parts, pumps, fittings, tubing, rads, reservoirs you name it.
