This is my everyday working computer, I have it already 3 years. Was never open since it never needed repair.
My fans were both emitting a high pitch noise when fully revved up. First I opened the computer and fully blowed out the cumulated lint with a Dust Off can (compressed air)
With this guide I disassembled both fans, and proceeded to unscrew the top on both of them and pulled out the rotor with a suction cup to reveal the bushing. After fully cleaning all the rotor itself, I applied a drop of PTFE oil (teflon) to the axle. Reassembled and presto. Like new!!!
