Lenovo G770 Fan Noise

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)?

Re: Lenovo G770 Fan Noise

currently there's no bios update for g770.

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