Having opened my MacBook several times before, fan replacement is one of the easier swaps to do. Tip: if your fan is running, but making upsetting noises, first check for a dust clog within the fan housing before you replace the fan. Lift the fan motor up without removing the felt tape seal, and inspect the heat sink grille for clogs (mine had a huge dust bunny on the left side, which was catching on the fan vanes). Carefully remove dust with spudger (or, ideally, a needle attachment on a 3M electronics vacuum). Good luck!
