I've re connected the fan connectors a few times already and repasted and undervolted the CPU/GPU.
Idle temps are in the 30's but still my left fan goes crazy when not doing anything.
This is driving me nuts. I might do a warranty RMA, but since I repasted, I am not sure if they will take it...
I had the same problem as many others in these forum. The GPU fan located under the power button (right hand side) was on max even when the GPU is on idle. I found a short term solution that makes the fan noise go away but only until the next time that you restart your laptop. So what I did is reboot into safe mode and use the display driver uninstaller by guru3d which is available online. After that I restart the pc and reinstall the nvidia driver, and voilÃƒÆ’Ã†â€™* after a couple of minutes the fan stops spinning out of control for the rest of the day. Hope this helps someone when they have to use the laptop in a public space.
One more update to anyone who might still care about the GPU fan noise on this laptop. My gpu fan was running on max even on idle and I finally got it fixed by installing rog gaming center 18.104.22.168 but more importantly by uninstalling MyAsus program. After uninstalling MyAsus and restarting the pc the fan noise went away! It seems to me that the problem was many different programs were trying to control the fan sensors and it malfunctioned as a result. Hope this helps other people as well.
