I received my Zephyrus GA503QS-HQ004T yesterday and since then I noticed that the GPU fan never turns on.
First thing that I checked was if the blades were blocked. They are not. I used a small zip-tie to move the fan blades through the grills. There is no resistance.
Then I tried a few more things:
I installed all the Windows updates.
I installed the 405 BIOS.
I installed the latest Armoury Crate and all the updates that it recommended.
I installed the latest NVIDIA drivers.
I disabled the iGPU in Armory Crate.
I plugged in the charger.
I tried to run two games (DOOM 2016 and Witcher 3) and Fur Mark.
The games were running on ULTRA and I was getting between 80-100 FPS on average. Sometimes more, sometimes less.
The GPU fan never turned on however.
Armoury Crate reports 0 RPM, even if I manually set the fan speed to 100%. The fact that the GPU was running at 95% did not change this behavior.
Another weird thing is that the BIOS only shows the CPU fan.
I also tried the following:
- reinstall Armoury Crate
- remove Armoury Crate and install MSI afterburner (the FAN slider is greyed out in MSI afterburner)
Can someone verify if they are getting the same behavior?
Before I take it back to the store where it came from, I want to make sure that it is an actual hardware fault.
