Cleaning out the dust

After hundreds and even thousands of hours of run-time, the inside of the computer [especially the Power Supply and CPU fan and Heat Sink] gets 'clogged' with dust which prevents proper Heat Dissipation.

Symptoms of dust build-up

A common symptom of dust build-up, is a sort of 'screeching' sound coming from the computer's fans.

Another symptom of dust buid-up and over-heating is frequent shut-downs or restarts.

Clean the fans and heat sink

Pull the cover off and blow it out with a can of air. Do it outside, and try and blow the dust away from the drives!
