i have seen people make waterblocks for their gpu, and ram on their video card. and they seem to have good results.
i mean, think about it, if watercooling is good enough to cool a cpu that is overclocked, then it should be pretty good for a video card, right?
but if you dont already have a good water cooling system, then you might want to just look into a good air cooling solution. because it will just cost too much to make a watercooling system just for your video card.
or maybe you could make a system water cooling setup.
cool the cpu, video card, chipset, and hard drive. then have no fans, except for the psu fan, unless you can figure out how to water cool those...hehe
then you could have a close to silent system...and it would run cool.
