Hi, I have the Tuniq Tower 120 Extreme cpu fan, and the backplate apparently is just slightly hitting my case behind the mobo because my comp won't even post when turned on (it boots up fine when sitting on a piece of cardboard and I also took some pliers and slightly pulled the part of the case that's up against the fan backplate and it booted while in the case as well - but I don't think that's a good solution as it would probably bend back eventually). What could I put between the backplate and case wall to prevent this grounding issue, preferably that I could find around the house? Paper? Thin cardboard? It has to be very thin as there is almost no gap between the backplate and case.
