Okay. I'm far from being a Techie, but I'm getting there. Recently I've downloaded a GPU monitor for the Windows Sidebar in Vista, and my GPU idles around 64 degrees Celsius. When playing Minecraft recently, I've noticed temperatures as high as 95 degrees Celsius. Minecraft was the only program running at the time. This seems to be quite hot to me, especially considering I was only playing Minecraft, but I'm not in the know. My GPU is an ATi Radeon HD 4800 series. I do plan to open up my case and clean out the dust soon, but I'm concerned about electrostatic discharge frying my computer. I don't have the means to replace anything at the moment. Also, does anyone know of any good temperature indication software for CPUs, GPUs, etc? I'm not sure of the quality of the one I have. Thanks in advance.
