Warning: Some i7-6820HKs and i7-6700HQ have Uneven Core Temps due to Uneven Heatsink

The GT73 has fully separate heat pipes, but the GPU VRM heatsink is cooled by the CPU fan, but the CPU and GPU heatpipes themselves are fully separate and do not connect. You can repaste the CPU or GPU separately without having to remove the other heatsink (you do have to remove both fans to repaste the GPU, due to the VRM heatsink being cooled by the CPU fan, but not to repaste the CPU).

The GT72 has a heatpipe on the CPU go to the GPU fan (which is rather strange), and I'm not sure if the heatsink that pipe goes to is shared with the GPU heatsink or not (if it is, you would have to remove both heatsinks to repaste...a HUGE pain in the butt).

 

You're blind then

Not only myself, but hundreds of thousands or more other people have no problems out of the box.

We see all the real problems here, of the people that are aware of such resources, and many of those are OCD'ing to the max due to being hypersensitive to such issues.

Many go away happy with no physical intervention necessary, they only needed undervolting and proper interpretation of data - looking at all the points of monitoring between temperature peaks.

Most people don't need to delid their processors, unwarp their heatplates, and wait months for BIOS/EC hacks from Prema for their laptops - you on the other hand live 100% in that world.

So of course you would think everyone has problems with their laptops out of the box, because in the Clevo world, they do

 

The difference between persistent - which is what I have been encouraging you do be - and OCD is that with persistence there's a good reason for it.

With OCD it's often completely imaginary, or overblown. We get people like that in here all the time. Their temps are fine, but in their mind any reduction in temperature they can accomplish is an imperative that must be followed to its iterative end.

It's a fine line to draw, but obvious when you see it

 

Yes!!

This is showing improved evening pressure of the heatplate against the CPU!

You're temperature differential is about 1/4 what it was to start!!

You can stop now if you want.

At least take a break and think about what you saw and what you did, something might jump out in your mind that might be still keeping the heatplate from applying 100% even pressure.

As with all problems, the "last" fix doesn't always happen right away

 

That's great, low enough to leave as is, 2c-3c differential

Try Prime95 small fft and see how much further the differential jumps up...

 

Heh I'm too busy trying to flash my video card with an SPI flasher to try to trick the GT73VR from changing from a 7RE to a 7RF....(you can see my post in the pascal bios editor thread).
I was able to run OCCT between disassembles....

 

Even at 5C I will stop. I feel like if I replace every single pad with k5 pro, the HS will even out 100%. However, I am not sure I wanna go that direction lol.

 

Congratulations on your successful problem resolution, and OCD avoidance

I'm pleased this resolved so quickly, with such a problem it can take a longer time to find them. This thread started out that way, and took a while before the thermal pad height was noticed as being "a thing".

That's why threads like this are so important, to pick up and set new people on the right path quickly.

Maybe you could make a thread in your Brand forum, or a post in the Owners thread for your laptop with the problem and resolution, you've already got the info fresh in your head, and photo's of the problem too. I see you've already started, that's great.

Thanks for hanging in there

 

Yup I have been communicating my progress to the GT62VR thread since @encheels has been having temp diff issues. Thanks for the K5 Pro recommendation. It works really well. By the way, what are symptoms of VRM overheating? Does the CPU throttle? Just curious.

 

I haven't seen laptop CPU VRM problems, but I have seen GPU VRM problems, usually because the VRM's aren't touching the heatplate - have no paste or thermal pad.

I wouldn't worry about this if you aren't having any performance issues with the GPU.

While you had the GPU heatplate off, did you check the VRM's for coverage issues? Check your photo's, maybe you got lucky and captured the coverage with your snapshots.

I don't think it's worth pulling things apart again to check this, unless you develop GPU flakiness issues.

The Intel x299 CPU VRM issues haven't even been seen in motherboards for a long time - or very often, so I wouldn't map those onto your laptop.

Intel's x299 i9 spec lapse due to last minute extension of the i9 CPU line is behind the x299 issues, along with not enough testing time available for the x299 motherboard manufacturers due to Intel's rush to market.

For now I think you can stop worrying about issues like this

 

Cool I was just curious because of those super high quality fujiopoly pads. I do know my gpu pads are there 100% because I saw them every time I was pulling things apart lol.

I blind, Nahh
I wonder how many machines out there is in hands on clueless people who never know how the temp should be. All those who never visit forum like this and similar forum.

Yeah, you can imagine how many 10 thousand or more machines out there who run fully throttling, aka run up to thermal shutdown temp as AW's ceo Mr. Azor saying is quite normal. And I can't imagine how many out there with all other sorts of problems and thinking everything works exactly as intended. I blind? Nahh

Overheating of VRM will most likely trigger throttling mechanism.

 

I didn't include Alienware or Clevo in my statements, I said Asus, MSI, Acer, HP, all of which I've had many times over with absolutely no need for re-pasting, and they run for years problem free.

Maybe not completely blind, maybe it's Alienware / Clevo / manufacturing failure tunnel vision

There are plenty of vendor successful designs, with successful Production and QA results out there, far more than failures. They just aren't done by Alienware or Clevo.

 

Haha you guys are the best. Btw, applying that k5 pro was so easy. That thing does not liquidfy, I checked and it was there like a gum on my chokes lol.

Yeah, K5 Pro is awesome stuff to replace thermal pads, to fill in the gaps.

 

Yeah, I know Instead of create proper Cooling, they create other ways to successful stop all too high temp. F.eks with firmware Yeah, plenty of them make successful designs Hp is one of them

 

@hmscott Damn, Almost same clarity as my own statement. But hey, they missed a bit. More of yoo should share my thoughts

 

OMG... I have just realized I can disconnect the cpu and gpu heat pipes when repasting..... this means I can screw the cpu heat sink without having the gpu heat pipe connected giving me full even pressure on the cpu heatsink. When the gpu heat pipes are connected with the cpu heatpipes, the cpu heat sink sort of floats before screwing them in because the gpu gets screwed first.... ugh


Sent from my iPhone using Tapatalk

 

That's good, and maybe not so good

Disconnecting takes away the lift pressure of the heatpipes and other connected pieces, making it easier to press with even pressure the CPU heatplate on the CPU, and evenly screw it down.

The only problem I've run into when I helped someone that did this once, a number of years ago, was due to overtightening the heatpipes onto the CPU heatplate, while the other end of the heatpipes was fastened down too.

They put too much pressure on a heatpipe, and after a few days of use, they heard a *pop*, and the heatpipe with the most pressure on it "popped" it's weld...

So be aware that the tension works both directions when tightening these things down

 

Yup I get it. I will go one last time with IC Diamond. Temps are going up, going to use the most viscous stuff.

 

Btw new laptop cpu die was a bit scratched already. Seems to be cosmetic but was surprised.
Wondering if I scratched it while removing the original paste. I guess since it is already a bit scratched IC Diamond will not bother me as much lol.

Had the privilege of removing old k5pro from chokes while replacing paste with Kryonaut. Gotta soak it with alcohol and it peels in one go using the gc extreme spreader. If you do not soak it, dried particles will fall everywhere lol.

 

Yup, awesome stuff. It forms a hard barrier to air, keeping it from drying out like normal pastes.

Still not happy with the re-pastes / fitment of the heatplate? Or was this another device with old K5pro?

 

My gc extreme started to lose performance. Not sure if it was the way I repasted but when I removed the heatsink, I did not notice anything weird. I put Kryonaut today and noticed it is very viscous compared to GC Extreme. GC is almost too creamy and watery. Anyways, out the Kryo and I cannot believe the temps.

 

Maybe it was the Forza Horizon 3 game hammering the cpu and gpu.

Hello, I'm back with my Acer g9 593 and 6700hq with uneven temps. Quick reminder:

- I asked Acer to fix this and they've replaced the motherboard with the cooling system. no luck
- I re-pasted my CPU with arctic silver 5. nothing special happened
- I lowered CPU voltage and it fixed my issue, it never goes beyond 85C in real applications

But voltage lowering works only in windows, with working intel app and blah blah blah. I'm looking for a better solution. Any bits of advice? Better thermalpaste (but no liquid metal) maybe I can lay smth between cpu and cooling module?

My repaste procedure:

 

In my experience arctic silver 5 doesn't provide a huge boost over stock pastes. When i got kryonaut i saw some nice drops in temp. Also paying attention to the thermal pads can help. Sometimes they get torn or even are missing after a tech replaces the heatsink. And getting some high performance pads to replace them can also help temps. More heat transfered to heatsink instead of the inside of of the computer.

Undervolting with throttlestop is my pref. You have to run it every time but thats good when testing unstable undervolts. Also i found my 6700hq model more locked down in terms of what intel extreme tuning utility would allow (when compared to my 4720hq). Throttlestop let me do things like adjust the clock with the speed shift settings so i dont have to go to windows settings or reboot with xtu to adjust the non turbo speed. I dont even think i can undervolt core and cache independently anymore with xtu. With throttlestop its no problem.

 

Huh, people still use AS5 nowadays?

 

Arctic Silver 5 is still for sale everywhere, and lots of people use it

Not everyone is OCD, only about 2.3% World-wide...

"Approximately 2.3% of the population between ages 18- 54 suffers from OCD, which out ranks mental disorders such as: schizophrenia, bipolar disorder, or panic disorder. In the U.S., approximately 3.3 million people have OCD, of which you have 0.3 to 1% of pediatric population and 2% of adult population."

For the rest of us a good solid product that's inexpensive and solves the need for thermal paste reliably over 10 years (in 2019) has value.

I've applied AS5 to computers still running AS5 from 2010, and they never needed re-pasting, didn't pump out - dry out - or otherwise fail.

That's got value over a few more degree's of performance from products so new the ink isn't dry on their packaging.

Those new products still need to prove their value over 10 years.

But, if you are competing against yourself for that last edge in initial temperature drop, there are other alternatives. As it turns out it rarely matters at all, those last few degree's don't make any performance difference.

BTW, the curing time for AS5 is 200 hours running time, which is pretty long, and results do improve over that time, so be patient when using AS5

AS5
http://www.arcticsilver.com/as5.htm

Important Reminder:
Due to the unique shape and sizes of the particles in Arctic Silver 5's conductive matrix, it will take a up to 200 hours and several thermal cycles to achieve maximum particle to particle thermal conduction and for the heatsink to CPU interface to reach maximum conductivity. (This period will be longer in a system without a fan on the heatsink or with a low speed fan on the heatsink.) On systems measuring actual internal core temperatures via the CPU's internal diode, the measured temperature will often drop 2C to 5C over this "break-in" period. This break-in will occur during the normal use of the computer as long as the computer is turned off from time to time and the interface is allowed to cool to room temperature. Once the break-in is complete, the computer can be left on if desired.

AS5 is still viable.

 

Soldiers can get by on K-rations for a long time. College students often survive several years on Top Ramen noodles and coffee. Some folks actually like eating the crap served at McDonald's. But, nothing beats a juicy steak, a crisp and refreshing garden salad, grilled veggies and a delicious dessert. I suppose it's hard to miss something better if you never have it.

 

Arctic Silver 5 and other thermal pastes are not food, please don't eat them.

 

Yeah the post i was replying to said they tried a repaste with as5 thats why i brought it up.

 

It's not that AS5 is a really horrible product, it's just that there are so many far better alternatives. For someone that just uses their computer and has a cooling system that works well and they don't do much overclocking, etc. it is certainly better than some of the lame alternatives floating around out there, and better than the waxy pad crap used by most notebook OEMs from the factory.

 

I too fell for the Kryonaut hype, repasted all 5 laptops and 3 desktop only to find some laptops (more frequent usage) were throttling (maybe just my imagination) so I changed them all again after three Months with Noctua NT-H1 (no curing time) and it's holding up so far.

 

Noctua NT-H1 is still running on computers first built in 2007/8, with great temps

Kryonaut works, but like all pastes it is application dependent. AS5 and NT-H1 also perform well if applied well.

Glad to hear you settled on a non-conductive paste that works for you

 

From what I have seen. Most thermal paste should manage heat from 40-45W Cpu Package Power or a Mobile Core i7 running 3.0GHz.

 

Dell, really? I still dont why would they do thet tri-why? Heatsink design. Already the temps are burning AF, and now this!!! If they dont fix this is r5 revision, idk anyone will even buy a AW!

 

For idiots by idiots.

 

No shock why @Papusan hates these bga craps!

 

@Papusan recommended me Phobya NanoGrease Extreme a few weeks ago. Tested it out and it definitely helps if the heatsink is slightly uneven. The paste is very thick so I am not worried about pumpout. Saw quite a decline with Kryonaut unfortunately even though it performs well in the beginning. I think this paste should only be used when the heatsink is perfect but you dont want to risk it with liquid metal paste.

 

Btw only thing i like about alienware, those sexy rgb lightings on bezels and side panels,those rgb mousepads, and that graphics amplifier port!!
Would really love to see this kinda things in the clevos!!!

 

Thats nice to know......that OCD is actually ranked as a mental disorder...I am very OCD about things and imperfections nag me to no end until I fixed it.

I saw a Clevo laptop recently with a RGB trackpad similar to Alienware. I am sure it will be implemented in more systems.

 

Where? !!
Which model was it?

 

I dont know which Clevo barebone this is exactly, but they have it at various Clevo resellers.

https://www.pcspecialist.co.uk/custom-laptops/proteusV-15/

It also has the RGB stripes on the front similar to the AW15R1 and R2 series.

 

That IS NOT A CLEVO!!!
Pcspecialist manufacture some laptops by themselves too, this being one of them!
That thing is not a clevo!!

 

Strange, I saw them at other outlets as well. I wonder who the OEM is in that case.

 

Also saw that laptop at cyberpowerpc!
https://www.cyberpowerpc.com/system/Vector-II-Z-15-VR-500-Gaming-Laptop

 

@Galm ?

I remember something about the vector series but can't remember. Galm found the OEM website with really bad english.

EDIT: http://www.mechrevo.com/

 

Ah I saw some other barebones from them on Aliexpress, I wonder how the quality is.

 

Correct I’d love for myself or someone more important than me to get their hands on a unit or two to review. We still know very little about them.
