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

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.

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...


Yea I basically just tried to estimate how much i would need to glop on there for it to "fill out" and make good contact. Couldn't be assed to wait for pads to ship haha. Just make sure youre using non-conductive, or if it is conductive, make sure its not spilling out the side.

Hi, is anyone experiencing simultaneous fan speed up then down (you can here the fan swirl fast then after a few seconds it swirls slower, then faster again, then slower) all at around 40~55 degrees?

Does anyone know of any fan RPM monitoring application? HWMonitor only captures CPU fan.

It's quite alarming to hear the fan go fast then slows down immediately after..

Asus ROG GL702VM


Yes. My Skylake GL702VM does this all the time in that temp zone. Why, I dunno. I assumed the controller has a heavy right foot. 🙂

A few months ago I took the case off and watched the fans, as I thought one might not be working. So I had it on it's top, lid closed, plugged into an external monitor. (I had already opened it up before for upgrades.) Here's what I learned:


  • the 3rd fan never ran. No matter the load, no matter the settings. And I couldn't find what fan it was for awhile, let alone how to control it. I finally found the GL702VM profile for NBFC and as soon as I loaded NBFC, the 3rd fan fired up. But only if it is set to a specific percentage speed. When set to "Auto" the fan never runs.

  • Worse, the 3rd fan is not adaptive when set via NBFC. IOW if set manually to 50%, it runs at 50% no matter what. This makes sense of course, given that the Auto setting is useless. But it means you have to remember to set the fan manually to 100% before gaming.

  • You know how some people say their system fans spin down to 0 sometimes, while others swear by apps like HWInfo that say a fan never goes below 1800 or 1900rpm? I watched it happen with the back cover off. All 3 fans would be stopped, while HWInfo would say the CPU fan was turning at 1900rpm. This happened several times. Something is lying like a dog in the hot August sun.

I noticed that Asus has set PROCHOT at the max limit of 100C.

This is why you see such high temps. Asus allows the cpu to run that high before throttling, and in the past, my laptop did shutdown because it couldn't cool down fast enough as it was pinned at 100C.

PROCHOT 100C seems to allow us to run turbo boost longer, but it can get really hot.

Other laptop brands have lower PROCHOT, so they throttle sooner.

Correct me if i'm wrong, but we do not want throttling right? Lower your temps via re-paste/mods and PROCHAT becomes a non issue.

Can someone please tell me how to undervolt my GL553VD? I want to undervolt the GPU but the instructions in this thread show the one for GTX 1060 while my laptop has GTX 1050.

I have no idea how clocking works so help would be appreciated.

Download and install msi afterburner. then top left of the core clock bar is a tiny three bar graph click on that. Its the voltage curve adjuster. You do it in there . more to it than that though.
The 1050 has less mhz core speed that's the main diff. These cards come configured, especially 1050, with lots of voltage.

I have tried the MSI Afterburner fix, however after pasting the profile in the profiles folder, I cannot select it. The profile numbers are greyed out, I cannot click them. What am I doing wrong?

does anyone else experience a cold boot issue with a CPU undervolt applied? Bascicaly i'll get the BIOS Asus logo and then a black screen with the laptop frozen like that. I need to hold the power button to shut off and when I try again it boots into windows without trouble.

If I remember to revert the CPU undervolt before shutting down I never have any problems, or doing a warm reset and warm cold boot always works as well.

I have never experienced that. What kind of uv have you applied?

currently -110mV

funny the last couple days it hasn't done it.. I'm not sure what is going on.
