    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?

    The battery has just finished charging and I think it's okay now, is it possible that this new battery I have caused problems with the fans recognising heat or something?

    I don't know if this is the cause or not, but it seems to me that most of the people with fan speed issues are the people using programs such as smcfancontrol.

    During my search on the internet, I found that it was mostly people not using SMCFanControl that had issues.

    Same here! hahaha When I started reading about temperature and fan control, I said to myself, "What does this have to do with the MBP update and us going crazy about it?":confused:
