I have jumped over to water cooling. I got tired of my PC sounding like a jet engine at take off when I booted it up. Personally, I like it a lot more. I use the Zalman Resarator and love it. Easy to set up, easy to maintain, and easy to use.
The only problem I have right now is that an air bubble formed in the pump when I took it home with me over the Christmas break. It makes this rattling noise. I have instruction on how to fix it, but it involves unscrewing the bottom of it. Me and my ex-defensive lineman roommate couldn't get the thing off while trying to remove it at the same time. I could find something long and narrow that would reach the bottom, push down on both the valves while moving the reservoir around, and hope they would come out. However, I can't see down in it and work at the same time...
