Replaced both fans on MacBook Pro 15" (A1226)

My Problem

Noisy fan(s).

My Fix

Very smoothly, I did it with my 10 year old, he enjoyed the experience. I let him remove and replace screws.

My Advice

I made sure I taped the screws as I took them out to a piece of paper where I wrote the step number. The instructions were very clear, however connecting the tiny harnesses required the use of a strong flashlight to illuminate the connection point and then use a lot of caution in snapping and/or sliding the connections together. The process to replace both fans took 90 minutes allowing time for a teaching experience for my son. He now has an idea what is inside a laptop. Well worth it !
