I was cleaning a dusty laptop fan with compressed air for years until a friend showed me the right way.

He held the fan blades still with a toothpick while blasting it, which stopped the motor from spinning backwards and potentially generating current that could damage the board, something I never considered.

Actually makes you wonder what OTHER common cleaning tips have hidden risks like that.

My old PC repair boss showed me that trick ten years ago. Blew my mind. I used to just let those fans spin wild. Felt like an idiot after.
