Liquid cooling

I was looking through a Maximun Pc mag and saw a sight called cyberguys.com; they had a self-contained liquid cooling system that sat on the cpu.. Anyone had any experiences with these????

Chaos, what's the make & model of the cooler you're talking about?

He's talking about those cheapy ones that have a tiny radiator over a fan that's over the waterblock and everything clamps to the cpu. It's performance is lower than a similarly sized air cooler (junk in other words).
