[AN515-52] Cpu fan not speeding up under load

datfounder1

Part Number: NH.Q4AEK.002

Bios: v1.24

So recently I have been noticing a decrease in sound in my fans. At first I was like good but I then checked nitrosense to discover that even under 100% load, the cpu fan was spinning at about 2500RPM max while the GPU fan was 4000 - 5000 RPM. I decided to turn on the max fan speed and It still did not work. Gpu fan was 6122RPM and CPU fan was 2500RPM. I tried reinstalling nitrosense but to no avail. Also this had started when I was on a previous BIOS version so I ruled out that this is a BIOS issue.

Here are some screenshots to show:



Also in this screenshot I found it wierd that with coolboost on the cpu is at 600RPM while the gpu is at 2500RPM:

It is possible that the fan is not lubricated, so the friction is preventing from spinning faster.
