Note – Unclog Heatsinks and Fans – System cooling is affected by dust and
contaminant build-up. Therefore, you should open and check systems approximately
every six months (or more often in dirty operating environments). Check system
heatsinks, fans, and air openings. If necessary, clean systems by carefully brushing,
blowing, or vacuuming contaminants from the system.
