Hey all!
I just purchased a second Sapphire 7870 OC and crossfired it (which produced wonderful results) but when my PC is standing vertical, the fans on the card make a really bad knocking sound when the on-screen graphics start getting intense (Bioshock 3 and Skyrim so far).
I tried making sure the screws were down tight into the case, but it didn't make much difference. Any suggestions?
