I have a MAXX pc (the one with the side panel like a door), but the questiion is what is the safest way to get my pcu fan out so I can clean it( the one in the metal casing and next to that I have a fan which is black with 2 white switches one on top and the other on the bottom of the fan so I can release it but I cannot seem to get it off to clean it is there something that im doing wrong. The reason for me wanting to do this is the computer is about 2 years old and through that time my fans have got nosier.
