Eeek! Worried about PSU *solved*
I was lying on my bed when I noticed that the fans in my computer started going faster and slower (I could tell by listening), and the case fan dimmed and got brighter randomly. The two case fans are molex, so the motherboard controlling the speeds wouldn't be the reason why it is doing this. I do have two fans controlled by the mobo (the CPU fan and a fan blowing on the harddrive) and these I believe are set to change according to the temperature. I never noticed it doing anything like this before, and im kinda worried. Is it the PSUs fault, or would the two other fans varying speeds cause the power to fluxuate (sp?) enough to make the case fans change speeds? At one point it sounded like all of the fans pretty much shut off and then immediately turned back on.
I apologize for the lengthy post, but I really appreciate any replies.
