I'm not sure I'm following. Are you talking about strapping a Corsair unit to one? I mean you could, but cosmetically it wouldn't look that great because you'd have to ghetto up a mounting solution then buy ugly heatsinks to keep the VRM and VRAM cool. Either that, or buy a contraption to do it, then you're out money. Drogos had 2 970s and lives in Florida so there was some benefit but even later he found out that ditching that setup to watercool a single powerful card was better.
I mean it wouldn't be bad for an experiment but I just don't see the point when a 970 is a cool running chip already.
For a 970 I just don't see the benefit at all.
