Don't know about the fan producing enough electricity to make a difference, but avoid any kind of vacuum to removed dust or lint... we have seen a large number of ruined computers from the use of vacuum cleaners both small and large... It seem that anything that sucks dust can product static electricity that can damage a system board... or other components inside a computer case or component.
