Crazy fan noise no longer a problem

Mi Problema

The fan on my macbook pro would occasionally make an extremely loud sound. After taking it apart and oiling the fan a couple of times, I decided that the temp fix was way too temporary.

Mi Solución

I followed the instructions on this site about how to replace the fan (actually I followed these instructions the first time, when I oiled it)

Mi Consejo

Just follow the instructions.
