I built this PC over a year ago. Recently I've been hearing the fan get noticebly louder when I do very basic things, like click on a new web page on internet. I have an I7 4790k with a Cryorig H7 fan. It's not the best fan but better than the stock fan I presume? The sound is very noticeable when there is no other noise in the room. Is this normal for others?
