and if i crank up MSAA it should tax the gpu more and the power should go up...

 

Depends on the engine, and implementation of MSAA. TXAA is even more taxing though.

 

Do you have an example where you got more than 200w?

 

3dmark benchmarks

 

Ok. Tried Timespy for the first Time and got 202w @stock speeds Happy with that now. Thank you

 

no thanks brother

 

@doofus99 i've ran a few cinebench tests, and my cpu is alot cooler now when bencharking at the same clock speed.

the first 2 pictures will show the before, and the last 3 the after.

 

CBR-15 seems still a bit low. The 3DM FS physics score is better, but the graphics score jumped down near 2k Could you post what clocks speed Dell have put in their different overclock profiles? And what clocks speed for all cores is used with their adverticed 50x oc profile? As well test Cinebench R15 with the max oc profile. Thanks

 

It does not matter how much copper the GPU side has. If its temp is cooler on the GPU side vs the CPU side, heat will not move in the direction of the CPU.

 

@Papusan 3dm dropped because it was without oc. My score is similar to phoenixs score with his LMed titan

 

It will, because they're shared. Have you seen a picture of a Alienware 17 R4 after some abuse from the Witcher 3 ?

The left side is consistently warmer than the right side, because the heat is not replaced with the cold air fast enough to cool down them pipes.

Even though the temperature is lower of the CPU, as soon as the gpu heats up, the the CPU goes up with it. That's how laptops with shared heatsink work. That's why you have to test with both a video card intensive, and cpu intensive benchmark or games. If you do not stress your heatsink enough, you won't know if you have a good system (without the core imbalance, and cpu overheating due shared heatsink).

 

Because there are many threads and posts of AW with improperly fitted heatsinks, I think we need to establish first that we have properly mounted heatsinks. Then we can rerun tests to see how the rest of the laptop behaves.

But even if we fix the overheating CPU, there are more problems:

1) overheating PCH - over 92C and rising - apparently it has not even a passive heatsink of the R4 - not sure how it's on the R5.
2) overheating SSD - over 92C and rising - could this be radiated heat from elsewhere? Otherwise why does the SSD heat up even when not used but when the GTX 1080 is being used?
3) overheating keyboard - over 50C around the left and the right "shift" keys.
4) very loud fans - it's like a little hoover blasting 2 feet away from your ears.

Is this the price to pay for the laptop being so gorgeously thin? And gorgeous in general!

 

@Papusan FS with latest drivers, maxed Fans. Stock CPU and GPU

https://www.3dmark.com/3dm/26510017?

 

well it seems much better. this is my score for example.

 

So Dell has created a heat sink that defies the laws of physics by causing heat to move from a colder object to a warmer one? Wow. They should get a Nobel prize for this engineering feat!

 

If you cannot see correctly then yes.

Go look for yourself.

 

From Msibook with stock clocks and same driver. But not maxed fans https://www.3dmark.com/compare/fs/15483257/fs/15451960#
Could you run stock fan profile and post results? Don't force maxed fans.

The Gpu cooling can't of load heat from Cpu if Gpu run full speed(Typical Unified HS design).

 

Nah he is right. The design of this heatsink is that air is also pulled in from the right side where the GPU is located (not mistaking this with the backside right exhaust ofcourse). The GPU heatsink crosses the CPU heatsink towards the left exhaust with one large heatpipe. This heatpipe also heats up the CPU partly. I know why they did it like this, it is to keep the WASD area cooler. But it does cause a 15~20c increase in CPU temps when the GPU is also stressed.

Keep in mind that the GPU pushes a lot of heat than the CPU, so the CPU side of the heatpipe is still the cool side compared to the GPU side.

 

Exactly. When the GPU is not under load, it will draw more heat from the CPU side. However once the GPU is under load this greatly limits the amount of heat it can draw from the CPU side causing the CPU to get much hotter.

 

The heat from Gpu will flood over Cpu HS no matter due it's design. Unified HS design is only useful if Gpu is compleatly disabled. Cpu will always put out load if GPU is in action.

 

Only until equilibrium is achieved. Putting the GPU under load is akin to raising the ambient temperature. However, once the CPU side is warmer than the GPU side, heat will no longer flow from the GPU side to the CPU side. The one caveat would be is if the difference between the CPU heat sink temp and the temp the CPU is reporting is large. For instance if the CPU is reporting 90C and the actual heat sink on the CPU is only 70C (i.e. poor thermal paste or uneven, loose heatsink), while the temp on the GPU and heat sink is 80C this would cause heat to move from the 80c GPU heat sink to the 70C CPU heat sink even though the CPU is warmer.

 

Heat will always flood over this pipe market. It dosn't work exactly the way you explain. The pure HS Cooldplate aint as hot as you think. The pipes don't go into the pure cpu die.

 

I am not disputing that. However this will only occur if the temp is lower on the CPU heat sink vs the GPU heat sink. Once the CPU side is warmer, heat will no longer move from the GPU side. Heat does not move from a colder object to a warmer object.

 

Gpu max loaded (lets say 190w) would never survived with the 2 wimpy pipes capped at Cpu. It would boil to death. You can have a hell lot hot Cpu, but the heat output from Gpu would still go to the cpu side. You need to understand the difference between TCase vs Core Temp (See top of HS as Case Temperature, who always is lower).

 

I added that caveat in my post you quoted - you might want to read it again. Once again, heat does not move from a colder object to a warmer one. If you or Dell have discovered a way to do this, I would encourage you to collect your Nobel prize.

 

If you think 2 wimpy pipes capped at Gpu heatsink can cool +190w full load then you have to re-think your posts/thinking. Will never happen. See f.eks... Cpu run hot, hotter than Gpu but not throttling and all pipes from GPU is capped and heat will only flow in one direction from GPU to the Gpu grills through 2 wimpy pipes. Nope, won't work.

 

Like I said claim your Nobel prize if you have discovered a way to move heat form a 80C object to a 90C object.

 

You forget that Heat pipes rely on a temperature difference between the ends of the pipe. Not in the middle or 3/4 of the lenght aka near the higher heat source (call it top of CPU coold plate).

 

No, heat will not move from an 80C heat sink to a 90C heat sink regardless of what the grill temps are. Moving from left to right, the GPU grill temp could be 70C, GPU heat sink 80C, CPU heat sink 90C, CPU fan gill 60C. This would still not cause heat to move from the GPU heat sink to CPU fan grill due to the CPU heat sink being warmer than the GPU heat sink.

 

From your understanding of how it works... As long Cpu temp is higher than Gpu (and we know about the Cpu heat problems in the newer AW line), the Gpu will always be cooled by 2 wimpy pipes in mentioned models. And I have never seen single wimpy pipes handle up to 100w heat each (2 pipes from Gpu to the Gpu grills in the Alienwares). Oh'well I shall not bother you with more of how things works

 

And I will no longer bother you with the 2nd law of thermodynamics!

 

You must be pretending not to understand what's being told or you really fixed on your knowledge of the 2nd thermodynamics law without getting the full picture of the process and how it works in this case
For example, can't you understand that if GPU is already 70C and CPU 80-90C+, GPU's temperature will be sustaining the minimum temperature of the whole heat sink and its pipes, therefore higher CPU temperature will be increasing the overall temperature of the heatsink.. It's the same as ambient temperature, the higher it is, the higher CPU/GPU temps will be.. Isn't that obvious?

 

lol you do know that the gtx 1080 can create 200+ watts of heat, where as with the 7820HK you have to be lucky to cross the 90+ watt. Go read again how heatsink works brother, i've fixed planes for insel air, and KLM.

 

Yes, I clearly stated that in my earlier post concerning the ambient temp of the system increasing when the GPU is under load. I am not sure what your point is?

 

I do. However if the GPU is reading 80C the GPU heat sink is going to be less that 80C. Same on the CPU side. If the CPU is reading 90C the CPU heatsink is going to be less than 90C. My point is that if the CPU heatsink is hotter than the GPU heatsink then heat transfer will be going from the CPU side to the GPU side. In all the testing that I have seen on these, the CPU is always hotter than the GPU implying that the CPU heatsink is hotter than the GPU heatsink. The caveat (as I noted earlier) would be if the CPU had poor heat transfer to the CPU heatsink (thermal paste, poor connection etc). My position has been that heat will not move from a cooler heatsink to a warmer one as is being proposed.

 

Well, you have all those discussions about thermodynamics. If someone is brave enough to change thermal paste on the CPU( I personally have no idea how to) then we gonna find out if this improves things.

By the way, do you get those new windows updates stating that we have to uninstall the hybrid drivers or something? It fails to install the updates. I checked on microsoft and said we should be waiting for a new update as this is just a warning to prevent us from installing an incompatible update. No need to uninstall anything.

 

My point is in my previous message. And if you understand the relation of ambient temp to the system temperatures, but you can't understand that simple example, well.. You don't have to

 

I do not disagree with you. I am not sure what your point is other than ad hominem attack rather than addressing my position that heat will not move form a cooler heatsink to a hotter one.

 

There is always a heat transfer from hot to cold as per 2nd law unless, like in a fridge, external forces are at play.

In our case heat always flows from the CPU (very hot) into the GPU (less hot). But HOW MUCH heat is determined by the temp differences and of course things are better (for the CPU) when the GPU is off, and things are much worse with the GPU on because there is less heat transfer. The GPU/heatsink is NOT pushing heat into the CPU, it is absorbing less!

In other words in this design the CPU **depends** on the combined heatsinks to maintain a say, 80C temps, because a lot of heat transfers from hot CPU side to colder GPU side. And this transfer continues when the GPU is on, but now at a lesser pace because the temps differentials are now smaller. What about the GPU fan which also comes on? Well, as we have seen it is crap because the overall temps rise, on all heatsinks, inside the whole system, so the GPU heat + GPU far are NOT neutral and do increase the system's temps, including the CPU.

This is a very bad design which leans to an underused (they hope) GPU heatsink side to draw heat from the hotter CPU.

And the whole design crumbles because the GPU fan is not man enough to draw the extra heat from the GPU thus raising all temps everywhere, including on the poor CPU which is now cooking.

The solution would be a combination of
(1) add better thermal grease on the CPU
(2) remove thermal grease from the GPU
(3) improve the GPU fan
(4) improve the CPU fan
(5) do not use the GPU so much

The fact remains that if I cut off and disconnect the GPU heatsink from the CPU side, then the CPU will cook!! Whereas the GPU will work MUCH better, because heat only goes from hot to cold.

 

The 17 R5 just became available in Australia and I am considering getting one, just had a question:

- Does the GTX 1060 model have the same heatsink and new design as the 1070/1080 models? Thinking of getting the lower GPU and just using a Amplifier if I want someone with more GPU power, noise is important to me

 

They will have the same heatsink design, however, the 1060 is less powerful than the 1070/1080 so you shouldn't have the overheating issues.

Or not as much, depending on which CPU you decide to get.

 

Did anyone notice any mouse lags randomly for 1 sec or so? What may be causing that?

 

Nah the CPU has enough cooling from the 2 out of 3 heatpipes. So it wouldnt cook but the GPU just adds about 100~150watt of warmth to the CPU side when active. With good heatsink pressure and good thermal paste the thermals should be good. The largest problem is the heatsink pressure on the CPU die, something a lot of brands now seem to struggle with though. Thats really not unique to alienware. With the right thermal pads, the right paste the thermals are around 80c for cpu and gpu around 65~70c which is pretty good with mild fan noise.

 

Have you tried this on R5 with Intel Core i9-8950HK and GTX1080?

 

Can someone upload the default wallpaper (theme) of 17 R5 please? I reinstalled windows on new drive from recovery drive but it is not there

 

are you on windows 10 april update ?? if so.. there is a bug which is well known.. mouse freeze and random GPU spikes on nvidia side.. they still havnt fixed that on patch tuesday.. this is not for all configuations.. but mostly found

 

So you have kept your laptop? Is it the i9-8950HK + GTX 1080 ? Did you have it repasted and/or the heatsinks resitted ?

 

Yes, I kept my laptop. No I have not repasted or anything, I bought one thermal grizzly metal compound and one thermal grizzly thermal grease but I do not plan to open the laptop. The only paste I put is a heatsink on PM961 NVME drives (one is 256gb and one is 500GB). I run 17 R5 without overclock and it is fine. I cannot find any reason to overclock yet. But, Is there any guide how to repaste/open the laptop somewhere (maybe for R4)? I would like to see.

 

Vickygameboy, This is what I guessed. Initially windows were blocking the update but somehow it got installed. Now I recovered from recovery image created before and mouse lag is gone. But I lost the default wallpaper and theme (maybe something else too). So, I am looking for the default theme. If someone can post please.

 

i plan to do a repaste. Have allready conductonaut, pads and nvme ssd heatsink here but wait for dell to swap my panel (broken pixel) or exchange the notebook (they discuss what to do)

When the hardware is ok, i will do the repaste and report

At the moment i run the CPU at 3,5ghz at ~75 degree and the GTX 1080 @1950mhz
