[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.

Hi everyone. I have GL502VM with i7-6700HQ. My cpu and gpu fans arun always at 12.5 % in idle. I used to hear almost no noise from fans while I was viewing some PowerPoint slides or pdf files. Evenmore I was able to hear them stopping and PC was pretty quiet. I don't know what is wrong. My idle temps are around 45-48 degrees for GPU and 38-42 degrees for CPU. These values are same as before but I guess something is wrong with fans.

I checked and cleaned them up with vacuum cleaner. Nothing has changed.

The only change I have made is I bought an SSD and installed the system on it. But I don't know it has anything to do with fans. Or maybe it is because of newly installed softwares etc. But my temps seem the same. What can be creating this problem and are there any possible solutions?

maybe because you used to have HDD running, and Notebook HDD tends to run a bit noisier than their PC counterpart and that noise masked your fan noise in the background?
i'm just shooting for luck, who knows.

Then there would have been much more noise when I had HDD. But I am pretty sure that it is not the case. For example I can't hear fans stopping at any time. Even if I wait for 10 minutes without touching PC, fan noise is same.

I wonder if it can be related to GPU drivers. Maybe something is wrong with new drivers which forces the fans to run constantly.:confused:

maybe it's the GPU power management mode in Nvidia control panel, you could set to optimal, adaptive or maximum performance. i set mine adaptive at global profile but maximum performance in each game profile. maximum performance in global profile forces the GPU to kick the core clock and voltage up even when you're browsing, maybe that's why the fan rarely stop.

My GL702VS with I7 7700HQ / GTX1070 is broken !!! Wont start anymore ...

Cant start it and cause i live in Germany i dont have any warranty ... so i will sell the components solo ...

If anyone is interested just send me PM (Motherboard with CPU and GPU - Bottomcase, IPS GSync Panel etc.)

Got original Bottom Case and bought a "new" one where i made this Mod. Temps goes down around 20-25 with this Bottomcase. I Have an invoice from 21. March 2017 bought in the USA ...

Try reinstalling your ATK Drivers, it might help.

What did you use to paste them? I have been thinking of buying those or some heatsink but I do not know what to use to hold them there

Thermal conductive adhesive tape. see this list: https://parafix.com/product-groups/thermal-management-materials/thermally-conductive-bonding-tapes/
do note that heat conductivity of these tapes are below thermal grease or paste/epoxy though, but i'm not prepared to marry those shims to my chips yet.

Well,

I think its time to cut the holes out in the bottom case. Ive tried undervolting the CPU/GPU, i have turned off turbo, set the power management to adaptive, i run my fans on max speed, tried a cooling pad (stay away from the U3 plus) and yet, my temps seem to only be getting higher. just shut down GTAv after my FPS dropped from 75 to 23 and temps were 87/85. I dont know what else to do with this thing so Im going to drill it. The plan is to cut out the 45mm circle directly below the fan and use a speaker cover to cover the hole. is there anything else that should be removed? i thought i read something about a foil tape? my main concern is that i work on a boat in the middle of the ocean and dont have access to the speaker covers until sometime after i get home in the next 30 days or so. does anyone think that it WONT be okay for approximately a month with large gaping holes on the bottom? I also plan to repaste after i get home using some thermal grizzly.

I wish i would of found this forum before i purchased this laptop. i could have avoided this headache all together...
