This is my first experience with a water cooling system, and its a winner. A leak is the only thing that will make me hate water cooling, but otherwise my system is cooler than ever; pun intended. I operate at 21 – 30 C without overclocking, and overclocked to 2.6 Ghz I’m at around 35 C. Using the newely updated, and incredibly stable Debian Lenny performance is better than ever. With preload installed and a strategically implemented ram disk system performance is surely maxed out with the processor operating at such cool temperatures.
