There isn't actually a fan on the side, just a vent. I pulled the tower out of my desk and on to the carpet, we'll see if it makes a difference. I'm only using the case fans it came with, and they're set to "medium", as I didn't think any more was necessary and didn't want them wearing out too fast. I took the side off while it was running to look at the fans, and they all seem to be running fine. It also doesn't feel particularly hot inside (despite the freezing air in my room), although obviously I didn't actually touch anything to be sure. I looked at the BIOS and left it open for about 20 minutes to let things warm up; the CPU temp started at 26c and seemed to peak at 36, and the system started at 9 and went to 16. According to chkdsk, my drive is clean.

This is the case: Antec 300 Three Hundred Ultimate Gaming Case - Black [0761345-08300-3] Cases Antec I'm using the fans it comes with. The top one is the one getting warm, I don't know about the one on the side as it's blocked by the side of my desk, but that side of the computer is pretty icy in general. The cables are all tied up inside. Typically it won't make the noise now, but I'll have a listen when it does and edit this post.

I'm not sure what the issue is, but I think PSU is a good bet. * OS: Windows XP Home SP3 * Desktop * Self-built * 2GB memory * Video card: ATI Radeon 4850 * PSU: Silverpower 500w * HDD: Seagate Barracuda 500GB My computer is a few months old, and sometimes when I play a game for a few hours it reboots itself (but only certain games). I figured that my PSU isn't man enough for my graphics card, but decided to leave it unless it happens more frequently (happened only 3 times in 6 months so far). Recently, my computer has been getting warm above the fan which it never had before, so I opened it and vacuumed all the dust which improved things, but it still gets a little warm where it used to be ice cold. On top of this, there's a noise coming from the box most of the time, which sounds like something rattling as it vibrates. Also, the HDD makes a noise like it's working when the computer is idle.
