Can you give a little more detail before I take my new laptop apart? Which heat sink? Where is it located?
My problem is the GPU fan runs full, half, or silent speed completely randomly, even when the system is using the Intel GPU and GPU Tweak reports it's only at 34 degrees C. So I don't want to start randomly pulling off heatsinks 🙂
I would like to say that I logged in just to reply to this comment. I have had this issue going on for about 2 months and I can say with full complete positivity that it is indeed the thermal paste underneath the heat plate. I already tried unplugging and plugging back in the fan cable and also wrapping it with the thought that may be the shielding was being interfered with which was making it kick on when it didn't need to be running. And that seemed to work for a smalle amount of time but not consistently!! I now don't think it has anything to do with the cable.
Just understand that there are 2 main chips next to each other which you can see on the motherboard. They are each surrounded by 4 screws. The left one I believe is the CPU but I'm not positive... the right larger one is definitely the nvidia GPU. When you take the heat Plates off you need to be careful because you can see that asus decided to put thermal paste on at least 15 plus different chips that surround what I think is the CPU and I know is the GPU.
I just recently built a new PC so I already had Arctic MX5 which is their latest thermal compound. That stuff is amazing I used it on my new AMD 5900x cpu. So after I cleaned the 2 chips off and also cleaned all of the paste from around them and additionally cleaned all of the paste off of the back of the copper heat plate that presses against them.... I then put a small strip of mX5 in a lengthwise fashion in the center of each of the chips. Finally I put the plate back down over the Fan and screwed everything back in together kind of equally going back-and-forth amongst the 8 screws that directly covered the 2 chips before I screwed in anything else and got them snug.
Finally I started the laptop backup again after I closed the case up. Sure enough the computer is absolutely dead silent now (before the left fan would come on 30 seconds after boot) .
I know it is working 100% because the function F5 button controls the fan from silent to balanced to Turbo. When it's plugged in the Turbo setting is available. So I Started up cyber punk 2077 and sure enough about 1 minutes into the game the fans turned on and increased speed, not ridiculously loud but I could definitely hear them and then when I put the system back to silent and shut the game off about 2 minutes later it spun back down to FULLY OFF. I could even see the rpm numbers correctly in armoury crate which did not work before they used to just show 0 instead of an actual number. Applying thermal paste is absolutely positively the correct solution. I guarantee it. Asus crappy thermal paste is the problem here.
