[GL702VM & similar] Solution to Performance issues / Overheating / Throttling / Whine

onjax
Level 9
Hi guys, I bought GL702VM and was upset with its ability to handle games and high load. I had immediate temperature jump to over 85 jump and throttling / frame drops in games. So I decided to understand how to improve things, even though, I already lost my warranty due to my experiments, but at least I can answer for everyone, that:
- the main problem of this notebook is inefficient, insufficient cooling system with too thin fans, too small heatsinks, vent holes in a wrong places (aside, not above the fans).

To prove this, I first changed the thermal interface to liquid metal. That doesn't solve the issue. This proves, the thermal contact is ok, but heat dissipation is bad. Second, I ran stress tests with back cover removed - helped a lot, about 15-20 degrees off. The proves that air intake is wrong in this system.

I also removed an antidust tape with holes covering all the intake holes. That helped by around 5 degrees and also brought down air noise.

Then I came to idea of downvolting CPU and GPU, thanks to devs of ThrottleStop and MSI Afterburner, we can do this with relative ease.

The result: Fan noise reduced by half. Temp drop is huge. More speed due to ability of CPU/GPU to properly boost to max speed.

For your information - CPU is responsible for about 30% of heat, GPU - for 70%. So best idea is to undervolt the GPU, but for best results go for both.

THE GUIDE - CPU
Variant A - Install Intel Xtreme Tuning Utility

  • Go to Advanced Tuning tab and Change Dynamic CPU Voltage Offset to negative value (move slider to the left). -100mV is a good starting point. Leave Mode to Adaptive.
  • Apply changes.

My CPU holds -150mV well.

Variant B - Install Throttle Stop 8.3 or above

  • On main window click FIVR button
  • Under CPU Core Voltage move Offset Voltage slider to the left. -100mV is a good starting point. The lower value the less heat.
  • Click Apply. On the same window you can save settings to make them apply every time you start the app.


THE GUIDE - GPU

  • Download and Install MSI Afterburner 4.3 or above
  • In settings turn on Unlock voltage control and Unlock voltage monitoring
  • Close MSI Afterburner
  • Download my Voltage Profile for GTX 1060
  • Extract profile to some folder and then copy file to "C:\Program Files (x86)\MSI Afterburner\Profiles". Click continue as Administrator when Windows asks permission to write.
  • Run MSI Afterburner, click on profile 1 (out of 5). Then press Ctrl+F. (1 - least heat, but may be unstable for some... 2, bit more voltage etc till 5.)
  • You will see my Voltage Curve (screenshot). What you'll see that it's flat until 1050mv. that means. 1050 will never be used, so will never be used any voltage except 831mV @ 1860 MHz and below.
  • Click apply to test this curve
  • If this curve is not stable for you - edit it to your taste: Click on 831mV dot and move it lower, so that lower freq will be used for that voltage, and for 1860 freq next available voltage will be used. Etc. Work with leftmost voltage dots to make everything stable.


This curve drops heat of GPU by at least 30%, which is huge.

THE GUIDE - COIL WHINE
Workaround described here: https://support.microsoft.com/en-us/kb/975530

Perform only these steps as Administrator:
1. At a command prompt, run the following command:
reg add HKLM\System\CurrentControlSet\Control\Processor /v Capabilities /t REG_DWORD /d 0x0007e066
2. Restart the computer.
3. Run ThrottleStop v8.3 or above and uncheck C1E. Click save.

In theory, it will make CPU a bit hotter while system is idle, because it disables some advanced C-states, but i didn't notice that in monitoring app.
That solved like 99.9% of the noise, and in addition, disabling C1E in ThrottleStop solved noise issue completely.

How did you test? For how long?

And what were the previous temps like on the same tests?


my test is using ROTTR:
- 1 benchmark directly
- wait on menu until CPU temp touches 70C then benchmark again.
I find this quite accurate to get max gaming temp since the other games never touched that high.
CPU temp is always higher than GPU temp, and usually about 5-6C difference between them.
to be honest the score is more or less the same than before the mod. but usually i test at night when it's cooler(i live in tropical climate) and the result you saw was tested at noon, so I need to conduct a test 1 more time later when it's night.

*update*
tested on 8.30PM
73367
I think I've hit the limit on how low these laptop air cooling temps can get.

73368
CSGO max temp
1920x1080, All max settings, 16 AF, 8 AA, Triple Buffering, V-sync on, capped @ 119 fps.

is this with the highest settings? My ROTR benchmark always hits 80, i have a gtx 1070.

when you say before the mod, is it with opolar vacuum or without?

I would say that is pretty good temps.

Not highest, it's the highest my GPU allows since mine is 3GB, going higher settings would just be counter-productive. usually medium-high with benchmark fps averaging @ 95 fps.
before the mod is with the opolar vacuums. i have to say, having 2 opolars and turning off turbo boost are by far the methods that bring down the temp most. and please do note that my opolars aren't attached perfectly so they're not performing at their best too.

I honestly believe 2 Opolars installed have just as much an effect on temps as drilled holes and may even work better. In conjunction with the bag of tricks of course (undervolting/disabling turbo).

yes, this i can confirm, but i have to try one more thing. the ventilation of the grill covers i use seem to be too tight, it blocks much of the cool wind from my cooling pad. i need to try benchmarking without the grills later.

hey, so how much difference did the opolars alone made on temps? Any idea? You must have noticed that when you bought them initially. I have ordered a chinese version, waiting for it to arrive.

before 2 unit opolar 81-83C, after 76-78C

From what I have seen the knockoff Opolars really don't compare but good luck !

Was just drilling the holes not enough? how are your temps without the opolars?

repasted the main CPU and GPU chip, as well as two of the small memory modules (I'm assuming thats what they are) that looked like they were lacking in paste.


When I repasted my CPU and GPU I noticed a few of the memory modules (I assumed that's what they were as well) were not properly pasted as well. I was going to order some thermal pads for them, but maybe I will just open her back up and throw some MX4 on them...
