So, last night, as an early Xmas present to myself I bought and installed a new ASUS hd 7850 2gb video card video rendering beast. It's putting out quite a lot of heat, even when idle and my CPU's stock heatsink isn't quite able to keep up, it's idling at 55c instead of 35, and under load, it heats up to 100c. I know I need a new heat sink, but what do I choose? Air or liquid? Which will be most effective at removing heat, yet still remain quiet? Oh and fit into a mid tower case?
