I really do recommend you go to G2G. Just to confirm, although nothing is wrong with cleaning your fans. Did you HOLD the fans within the case so they do not move? If not, you risk frying more boards, and overvolting things within it.
Please refrain from doing anymore work, and consult G2G Tech’s. They are a million times more knowledgeable then I am. I’ve worked with the, before, and never lead me stray.
