Hey Sebastian, Apple has been revamping their internal cooling systems a lot over the last few MacBook iterations. Because of this, the fans and connectors have been changing each time. Unfortunately, you cannot put a Retina fan inside of an older MB Pro. Check out where the [guide|9719|retina fan's connector is|stepid=36680] versus where the [guide|7516|Unibody's connector is|stepid=14816]. Hope this helps!
