I have a Corsair 750D case and am using the 2 stock 140mm fans in the front for intake, a Corsair H90 mounted to the rear 140mm fan blowing out, and 2 140mm fans on the top. The side panel of the case is vibrating rather loudly but stops if I put a weighted object up against the glass of the side panel to push it into the case. Has anyone else had a problem like this and found a solution besides putting constant pressure on the outside of the case?
