Hey i was looking at http://www.overclockers.co.uk/showproduct.php?prodid=GX-112-MS&groupid=701&catid=1914&subcat=1010 for sli. Then i see sound for these is 42dba which i consider loud, though im guessing its with the fans set at 100%? Whats a more realisic speed % while these are running in a game.
