Passive heatsinks & watercooling
 

I'm in the market for a new video card, and was considering getting the Sapphire 9700 Pro Ultimate package, with the passive heatpipe cooling. My question is however whether or not this heatsink will provide adequate cooling considering the fact that my computer is watercooled and therefore the only fans I have in it are on my radiator. I suppose I could add another fan or two if I HAD to, but I'd prefer not too.
