Hey, I have a late 2007 macbook pro and recently the fans have been going at EXTREMELY high speeds without the MBP being hot at all. I have SMCFanControl and iStat Pro and both of them said my MBP's temperature was around 55C though the fans were going between 4000 and 6000 RPM, I also checked the activity monitor for high CPU usage but nothing high there. I turned my MBP off for 5 minutes with a fan blowing on it just incase it was hot but when I turned it back on the fans immediately jumped back up to 6000 RPM. They're back to normal now but I assume it will happen again. Anyone know what's wrong?
