Every time i start my PC, a weird sound comes from my fan, it stops after a time, but can also start again. Is there a way to fix this or do i have to replace it? Also, what is the reason this kind of noise happens?
Fan is almost 2 years old. The noise is kinda like a rattle, like it's hitting something, but just checked, no strange object there. And i hear the sound mostly coming from CPU fan, but i think i've heard from power source fan too from time to time.
