Okay, so the fan that came with my HAF 922 is defective. The armature supposedly lost its magnetic center due to failed bearings. I can replace it, but I want to know if I can fix it myself. I have a low strength magnetic screwdriver, that's about the best magnet that I have. If I'm being a complete idiot and should just go replace it already, please tell me. Also, I only very recently bought the case, so would I actually be able to get this covered by that initial warranty?
