First repair job. After 5 years of use my laptop was getting heated quicker than the oven and making that antique modem noises. With 2 screwdrivers and a plastic card to pry the connectors cleaned all the dust inside the case and the fans following the fan replacement guides without any trouble. Huge thanks to Andrew for this very detailed page! Btw, if you intent to reuse the fans, be careful with the connector cables. They are not flexible, they bent easily and might break.
