Nothing will overheat a piece of electronic gear faster than a nice layer of dust build-up, and what kills gear? That’s right — heat. Well, that, and so-called “gravitational events,” but that’s for another article. Use cans of compressed air liberally. The intake/outlet fans are the biggest culprits. Best to locate where the power supply is, and go from there. Pro-tip: Turn off and unplug the gear, insert a tweaker (or the end of a cotton swab) to stop the fan from spinning, and spray away… The point is this: Clean is not just a state of mind. It’s also your job security and an indicator of how professional you are. If your gear constantly does not work, it follows that neither will you.
