  1 0 One of the fans in your MacBook might be going bad. The fans spin at very high speeds and the bearings on which they rotate can start to fail and become noisy. If your MacBook is still under warranty (or Applecare), you can take it to the Apple Store genius bar and they can run a diagnostic application to see if that is the problem. You can also do this yourself. Download the smcFanControll app from http://www.eidac.de . It will display the fan speeds in your menu bar, and you can monitor which fan is most active. The site http://www.ifixit.com has very good instructions for replacing fans, and sells replacement fans.

They might charge you for the repair, however. Tom Sackett commented 10 months ago | Report 0 0 +1 for SMC fan control. You can essentially turn the fans off for the duration of your session. This of course could fry your macbook if you let it over heat for extended lengths of time. Take Brian's advice also, turn off everything you don't use while recording. A browser with any flash running, even an add will make my powerbook G4 start spinning madly. pairustwo commented 10 months ago | Report Enter your comment or ask a new question New comments are not being accepted at this time.

  0 0 Close as many other apps as possible. The fan turns on when the thing gets too hot. Keeping the processing it's doing to a minimum will keep it cooler. Andrew Beck answered in Geek Week 10 months ago | Report 1 comment by Black Beetles in Amber… 1 0 That's not a solution, really. Most likely if the noise is too audible, it's a physical problem, either it needs new fans, a reapplication of thermal paste, or both.

  0 0 Lift the laptop off the table/desk to allow air to circulate. Close all unnecessary applications, including web browsers and email applications. place a small fan far enough away so the mic doesn't pick up the sound but close enough to keep air flowing around your laptop. Lower the brightness on your screen if possible.
