With summer heat still around, there is no doubt that your system temperatures rise a couple of degrees. I live in Southern California, right where the deserts are supposed to be. I must say that it is still extremely hot. On a typical good day, temperatures reach about 75°F inside my house; and on a bad day, they can hit as high as a blazing 85°F. It's certainly not healthy, not to mention comforting, to be in such a heated place. What would most people do when they're hot? They turn on their air conditioner. While we complain about heat, our PCs must be screaming for help. With each degree that rises in ambient temperature, it causes increased component temperature inside your case. Luckily for computers, Waffer Technology has invented their PAC 400, which acts like an air conditioner just for the computer system.
