I was put off from water cooling as soon as I heard about it. The first review I read was of a Koolance case in which the independent reviewer's system failed from overheating after 20 minutes. I'm sure they've had time to go over it and actually make it work by now... but I'll stick with my trusty fans like I'll stick with my trusty Intel.

Also, I've had a Cyrix based machine before (2 years ago). Nothing but problems. I'm pretty sure it was the mobo, and that they have ironed out any problems as well. But I don't take the same chance more than once. And since the first time didn't work out - the 2nd time will still be viewed as a chance.

I'm simply going to put in some quieter fans. And if it's not quiet enough... the upgraded machine (months down the road) will have a cpu fan, so it will be safe to disconnect some of the case fans.

Play it safe. Do it overboard; never have to do it again.
