Use a paperclip or some other object to carefully prevent fans from spinning on a shut-down and unplugged computer when the air might spin them.

Do folks really stick paper clips in their fans at night when they turn off their computers? I never turn mine off, so it's not an issue for me. This is not something I would have considered doing though. I can't imagine the slight, if any, rotation a powered down fan would encounter would be anything to worry about.
