How good of a job will the koolance exos do with a ocd x2 and two 7800gts in sli? I would get my own radiator and pump, but i need to place the radiator on top of the case, as inside would be too cramped with two cards plus a sound card and tv tuner. if i get my own, i would need to get some sort of external psu for the fans on the radiator, which seems a little ridiculous to get a new psu for two measly fans. i guess i could also find a way to route the wires, but that will look kinda ghetto, and i doubt theyd be long enough to stretch through the back so ill probably need to drill holes in the case. basically, is the version of the exos thats designed to handle 700w of heat good, cause some reviews werent ecstatic about it.
