Answer to: Playstation 3 Fan Teststraight from sony exact copy of email the persons name left out Hello Bryan, Thank you for writing us regarding the fan test. The fan will not remove dust that is in your system(s). It will not hurt any of your systems. All it is, is a force eject for a stuck disc and the fan comes on.
