I have a MSI GT62vr 7rd laptop, this 2 months old device started showing a weird behaviour about 2 days ago. While monitoring it's CPU fan speed I noticed a kind of fluctuating pattern when it goes up to 2600 and back to 360 RPM very quickly.

After noticing it with high CPU usage i've rebooted my machine and waited for all processes to end. Even with CPU was idle the fan was constantly going from 0 to 400 RPM constantly.

When everything points to a possible hardware issue something is bugging me. When I press the "Cooler Boost" mode, the fan goes up to 4000 RPM and never fluctuates. I was expecting a damaged fan to fail somehow while running at maximum speed.

I've tried everything but opening the notebook case. Updated BIOS, EC, Win 10, reinstalled Dragon Center (controller) and some other MSI software. Nothing worked so far.

This is driving me crazy, can you please share your thoughts based on your experience?
