A1150 fan was dead.

Mi Problema

My right fan was dead, never showed as running when I checked istat pro. Led to my mac running hotter than it should. Figured I would replace both since I already had to open it for the one.

Mi Solución

The only complaint was UPS delivered my fans a day late when I paid for next day air. The only difficult part was the small cable going across (and attached to) the left fan. (I forget the step #) Guide was thorough and VERY helpful.

Mi Consejo

Kapton tape! The electrical tape covering the fans and vent ports were very sticky and did not want to attach to the new fans. I covered the old tape with Kapton. Also, the steps that require you to remove cables taped down the mother board need to be replaced as well.
