post #1 of 4
Thread Starter 
Why do OEM PC's crank the fan up to 100% at startup?

Its a self diagnostic feature in oem pc manufacturers. They like to check the fan operates properly. Edit aswell as many newer gpus also.

Not only is the hardware being tested on startup, the OS and software that starts up peaks the Task Manager to no end until the Commit Charge is completed. Then the fan(s) wind down.

Dang beat to the punch.... main reason is testing as stated

Luckily, I have something to add:
I also like to think that since OEM PCs are meant for the tech-not-so-savvy and are rarely opened/cleaned, the quick CPU fan windup at startup might relieve the heatsink of some of the excess dust buildup
