How do you safely clean dust from inside the computer case?
Hi There> All answers state to get a can of compressed air. One answer states to block the fans from turning, ex. with a pencil- this is to prevent overstressing the bearings, and to prevent “creating” electricity within the motor windings, since, if you “turn” a motor, it becomes a generator. One answer states NOT to vaccuum anywhere near a computer, which is generally good advice, since, most vaccuum cleaners prduce HUGE amounts of static electricity, which causes sparks of high voltage electricity, easily 1/4 inch long. Hitting a keyboard or mouse etc. will cause the spark to follow the cord INTO the computer, and can travel across the entire motherboard, silently blowing up a dozen chips on its way. The other aspect of this is that “sucking” air, as in a vaccuum cleaner, is only efective in a very short range, while a blowing blast of air can be felt a foot away. One answer states that after blowing loose dust, use a 1 inch brush to loosen any other dust, and clean again– good adv
