Lenovo G770 Fan Noise

[Miroljub]

My problem is that fan speed constantly going on and off. When a CPU gets 100% even for a few seconds it immediately goes to high speed and noise is just unbearable.  Is there any way to adjust fan speed on Lenovo G770 (I already tried Lenovo Energy management and smart noise sensing option and it doesnt help a bit)?

Check for a bios update?

I couldnt find any bios on lenovo support site.

secondly, can you check if the issue persists on safe mode? could be driver issue.

tried running the pc in safe mode, issue still persists!

[yigit]

could be hardware issue. i suggest you to call lenovo support line to ship it back to service.

Can you report the bios version is it : 40CN06WW(V3.05) ?
