Hey guys,

I just built my first gaming pc. However, one of the case fan is making some "tick" noise like it is hiting something: fan noise.
Thing is, it is not always doing this noise and I don't know what triggers it: in the same conditions (gpu fans off and no software running), no noise.
Case is a 750d and the fan is the one behind the cpu cooler.
Also, I don't know if it is related but I have a grinding noise only when doing a cold start-up: grinding noise

Is it something to worry about ? Is there something I can do ?

Many thanks for your help !

Remove cables from the area around the fan, if that's not possible install a fan guard. If it sounds like the fan it hitting something 9/10 times it actually is hitting something.
