Personally, I'm a fan of vacuum cleaners rather than canned air. But, yeah, overheating sounds like a highly possible culprit, so cleanliness is always a good thing. Also, unless you have reason to worry about physical damage, leaving the cover off the case is a good idea. Less dust-suckage, and easier to get at whenever you're vacuuming the room.
