Hello,
I purchased a Acer Nitro 7 (2019) having model number AN715-51 on 18 May 2020. It was working fine until last week. I optimized my cooling performance with a Cooling Pad and running in MAX fan setting when under heavy load. Previously my GPU fans had a RPM of 6122 in MAX setting with CoolBoost enabled. But gradually the RPM of my GPU fan decreased over time since last week. Now it is under 3000 RPM and can not even reach to 4000 RPM even under heavy load.

My Configuration is as follows.
CPU: i7-9750h
GPU: 1660Ti(Mobile)
RAM: 8GB

It would be helpful if anyone can help me out in this.
