good video but if someone only wants to remove fan witohut disassembling full laptop:
you do not need to remove full heat sink if you just want to clean the fan, look where the fan is there is a small screw open it, and take the fan off there will be a small plastic jack with wire, carefully disconnect it from motherboard then clean the fan by opening. ,you can add a drop of oil or even engine oil or cleaning alcohol where the fan spinner is to make, it rotate properly in case som,eone wants to clean their fan or if it stopped workin,g you can buy a new fan on,ly and replace the old part. no need to remove full heat sink
