With pictures of the new nforce4 boards kicking about the net no doubt most people will be cacking themselves and dreaming of dual gfx card goodness but has anyone thought about cooling on the cards? Alot of the stock coolers take up an extra pci slot now yet the pci-e slots are right next to each other so how are they going to swing that one? I've seen some boards with three pci-e slots next to each other which would leave some headroom but how would you watercool them or put a zalman heatpipe on them etc? A DD 6800 block would work as the barbs from the bottom card would foul on the top card, you have to use an older block like the maze4 but even that would be hard as it would be a very tight bend for the tubing. Anyone got any thoughts or will i just put this down to another late night rant?
