Hi I have a few questions regarding my desktop. I had a new power supply fitted to my desktop last year, I have just noticed this morning, after running the desktop for a period of time, perhaps a few hours, my desktop gets quite warm on top, the power supply was replaced last year because the fan in the old one seized up. I have checked the fans below the power supply, I think there are two fans below, they seem to be putting out cold air although this morning they were putting out a lot of warm air, I have just checked the side, there is air coming out of the side vent too. At first I thought my cpu fan may be playing up but I am not quite sure how I would know this. I had a few problems with my pc on Thursday, it wouldn't shut off or shut down, I rolled it back and this morning I installed norton utilities and found several errors, in fact several hundred and fixed them. I installed speed fan, the temperature of the cpu seems to be a bit high, again I am not sure what the temperature should be, I turned the pc off for the afternoon, let it cool right down but I put it back on at 4 pm, after 2 hours it is getting warm again. Is this normal? Should I be concerned? There is some air coming out of the power supply itself but not a lot. What should my cpu temperature be? I assume that if anything serious went wrong my pc would shut off to protect itself? Also listening to it it sounds a bit noisy but it could be vibration on my desk. I have it sitting on a carpet tile. The desktop is one I had built a few years ago in 2012, I use windows 7 pro on it. I may be worrying for nothing but I pick up on noises and this doesn't quite sound right to me.
