I picked up a new pc over Thanksgiving break, and about a week ago I started hearing a noise (I'm pretty sure it is the fan) whenever I am either a.) running a lot of applications (iTunes, FireFox, Excel, Magic Online, etc.), or b.) playing WoW, HL2, or CoD2. I installed Everest to check out my system's temperatures, and for GPU it looks like I'm sitting at around 56-57 degrees (celsius) when I'm not playing games, and around 61-63 while I am playing games (even saw a 64 tonight for a second). For motherboard temp it goes from about 38-40 degrees when I'm not playing games, up to about 45-47 when I'm playing games. I am running a P4 630 3ghz with 512 mb of ram, and I've got a Radeon X700 256mb as my graphics card. I'm not a computer expert, so I'm wondering if my computer is in danger of overheating. The noise I hear is pretty loud, but I'm not sure if that is because I'm just doing too much for my pc to handle, or if it is just a loud fan. Any help would be greatly appreciated!
