I recently bought a Precision 3551 with i7 10875H

The fan makes a lot of noise, even in idle state. Meanwhile the keyboard is still very hot on the left.

I’m using 130W USB-C charger and windows 10 is on idle with no CPU usage, and no launched application. I checked the CPU frequency and it is always at 4300 MHz even on idle.

Is there a way to lower the CPU frequency on idle ? such high frequency is no necessary all the time.

I tried all thermal modes in Dell Power Manager, and Optimized is the less terrible.

 It will be a good idea to add a new set to Dell Power Manager : Slow, Cold and Silent
