My Late 2006 Macbook has a hardware issue where the Fan is running at full rpm. It stays way cool but it is still annoying. Is there anyway to fix this? I ran hardware check and it gave me an error code but I don't know how I can get what the meaning of the code means.

MacBook, Mac OS X (10.7.1)

    I was going to suggest you reset your SMC, which can sometimes fix a fan gone crazy. See


    However, if the hardware test found a problem, perhaps with a sensor, that's a different thought.  You can still reset the SMC, however, please post the entire error message with all the letters and numbers.  Someone can probably tell you what it means.

    Go to the Apple in the upper left corner and select About This Mac, then click on More Info (and then System Report if you are running 10.7 Lion or 10.8 Mountain Lion), then select Power from the left hand column of the System Profiler. Copy and paste the Battery Information from the top of the page back here.
