I ran iStat and here are my results: For some reason my computer's fan runs very loudly. Louder than any other computer around me. I use my computer for design, but everyone where I am at has the exact same computer, same software, everything. However, mine is the only one that is both running extremely loud, and getting really hot. I used to use it all day, but now only use it once in a while since I got the Mac Pro for all my work. What could be wrong or what can I do to fix it? Thanks! Just checked the activity monitor... For some reason, folding @ home was running at over 200 CPU! I installed that a while ago and must have forgotten. Seems a bit extreme, but I got rid of it. Hopefully that fixes it!
