Easier is impossible

Mi Problema

The problem: a noisy fan. Before buying a new one I tried to clean and lubrificate it with some sewing machine oil but the noise came back after a few hours.

Mi Solucion

Very easy repair, less than 15 minutes thanks to the ifixit tools. Just unscrew, change the fan which, and screw everything back.

Mi Consejo

Just follow the tutorial.
