So here is the thing and this is driving me crazy. I'll usually leave my PC on when I go to sleep I have a 1hr sleep timer on it so it goes to sleep and doesn't waste too much power yada yada yada. Anyways, sometimes I'll turn it on and it will make this horrible whirring noise like one of the fans (I'm thinking possibly my GPU fan?) goes absolutely nuts and is way louder than it should ever be normally. So I'm sure the first thing that pops into many of your heads is that it might be dusty right? Fair logic.
Here is the thing though I got this PC last april from newegg this started doing this around I'd say 6 months in to owning it. 6 months is awhile but I don't think its long enough for enough dust to build up to cause any issues. Secondly, and this is most likely the oddest part this only seems to happen when it is cold and only seems to happen whenever the PC sits for hours at a end. The second odd thing about this is if you simply put the computer into sleep state when this whirring happens and let it go to sleep then wake it up the noise stops every time.
I've not noticed any signs of dust or GPU failure either. No artifacting or other odd graphical glitches. I can play games just fine and the PC never seems to get too hot. Once I quit the game heat levels go back down as they should. PC is still pretty snappy. I'm not sure what is going on here. If this were heat or the like I think I would be having issues while I'm using it instead of being only a issue when I wake my pc. Considering its on a good 16 hours out of the day every day I'd probably have noticed if it had heat issues. The fact that it only really does this when its cold is the oddest of all this. I haven't had this issue pop up for me for months. Like basically all summer. Now were in sept and the temps are cooling back down and suddenly problem is back again.
So anyone wanna take a stab at this? I'm not sure I'm extremely worried because I've seen no really troubling signs or performance issues but I have yet to actually find a reason for it.
