So I came across this graphics card which is liquid cooled http://www.bit-tech.net/hardware/2011/09/26/cooled-gtx-580-1-5gb-review/1
from the articvel - they also forgot to mention that with all that overclock, a single 120rad aint enough to cope with all that heatware - even with a push/pull setup with fans.This alone should mean the XLR8 GTX 580 has some serious weight to throw around.
