GL502VSK GPU fan doesn't start automatically

[arya1]

Hi guys. I got a brand-new GL502VSK with latest bios version (version 303) and drivers.
While heavy gaming only my left side fan (CPU fan) spins and the right side fan stays completely off unless I manually set the fan speed to 100% in ROG gaming center. At 100% the second fan starts to spin from 0 RPM to maximum RPM but even at 99% fan speed, GPU fan at the right side of the laptop stays off. Does anybody here have the same laptop? I just want to make sure my machine isn't faulty.

Even after 2 hour of gaming only my CPU fan spins... The temps go as high as 95C for CPU and 89C for GPU but still the GPU fan does nothing except I manually set fan speed to 100% before the game starts. Then both fans spin at maximum speed and temps drop to ~77C for CPU and ~70C for GPU.
I read a post which said the GPU fan only starts to spin when its temp reaches 90C. Under heavy load my CPU fan spins so fast that it keeps my GPU temp below 90C only by 1 degree and doesn't let GPU to reach 90C.

Maybe there is something wrong with its sensor or something, but I hope not...My laptop is just 1 week old

It might be faulty. I have the exact same laptop with latest drivers and whatnot, and I have no issues.

It might be faulty. I have the exact same laptop with latest drivers and whatnot, and I have no issues. My temperatures remain at max. 80 degrees when gaming on games such as Battlefield 1, Overwatch, etc.

Have you done any undervolt or disabling boost mode? Mine has - 0.100 undervolt and disabled boost mode and in games like six siege temps become 88 Celcius on CPU. Is this a faulty model?

I haven't done anything to modify the voltage or general output. This is the out-of-the-box performance and cooling that I am getting.

I sometimes also make use of a laptop cooler when I connect my laptop to an external monitor, which seems to help a little bit, but not as much as I had hoped.
