Yea i have a crap load of fans running plus one really good heatsink. 2 faceing the video cards, and a grill in the front forcing hot air out. in all 9 fans now, lol its a little noisy but it does the job.
even then my video cards tend to get a little hot around 80c n load, but i am going to fix that tomorrow, with a pci fan faceing up to the video cards.
and removing one of the fans thats faceing the cards now.
its a server case black, can't think of the name though.
I wen't watercooling once, to much of a pain i think, also a risk of spillage to.
lol if this keeps up i might need a 1200watt psu

Also turbov is an awsome application that lets oc on the fly in windows, no need to go into the bios anymore, it doesn't oc ram though.
if your interested here is some more information on it, only for asus though.
