I am curious as to your impression of the latest water cooled units.




Search the case and cooling fetish forum at Ars for discussions of the various kits. I haven't taken the plunge (no pun intended) yet on my system. The only component of my current system that is particularly noisy is the fan on my old GeForce GTS. As soon as ATi releases the 9800 and 9900 (next couple of days supposedly), I'll pick one up, throw a Zalman on it and see if my system is quiet enough. If it's still too loud, I'll probably try a Danger Den kit.

Got any recommendations for first time buyers?




First and foremost, read as much as you can about it. Hit up Ars and search the forum. There are a lot of tweakers at HardOCP as well, though I'm not a big fan of their forum in general. Make sure you understand what's going on before you try it. The last thing you want to do is fry your gear.

Once you've done that, you can either buy an entire kit from one of the water cooling websites or save a little money and buy the pieces seperate.

There are others. I dig the look of the Danger Den stuff and they're VERY highly regarded.

The temptation to tweak is upon me.




Be careful. It starts out so easy and cheap in computers that you can get very hooked. Next thing you know, you're spending all your time and money on it. It's very addictive.
