Ok so I have a Mac Pro 2xQuad 2.66Ghz and the cores are always really hot even when idle. When I chat and surf the Internet I only use ca. 3% of the cores however the temperatures are at ca. 80 C° and higher when I do work. So I decided to Install SMC Fancontrol, however there is a big problem I can download it fine, I unwrap the zip fine and I can open the application. However as soon as I type in my password nothing happens... Its really frustrating because I cannot do anything I cant even delete it as it apparently is still running... Here is som more useful info that might help you guys: Mac OS 10.6.2 Snow Leopard 2009 Model I really hopw you can help me cause I really really do not want to overheat my wonderful mac pro!!!
