56C is no problem for a graphics card and nothing to be worried about. Most cards are fine running up to a little over 100C. You can ramp up the fan speed if you don't mind the added noise, or if you're really worried you can get an aftermarket cooler for the card. -- DFI UT X58-T3eH8, 6GB GeIL PC3-10666, PC P&C 610, EVGA GTX280 SC, Core i7 920 @ 166 x 20, Noctua NH-U12P in Push-Pull, Mountain Mods H2GO
