I was reading the post on water cooling and heard that if you buy the kit it doesnt help out temps much. One person said that if you built a custom water cooling unit that it is much better than the kits. I was wondering how to build the water cooling kit, and what brand of products to use.

personally i think radiator is the singal piece in water cooling that will change temps i would look for a dual 120mm fan one or if you got the cash go for a pelter rad that dosnt take you below 0C or else condensation will occur

To build a simple water cooling kit, you need to purchase...

CPU waterblock
Radiator
Resevoir
Tubing
Pump

There are some other stuff in there that is handy to have but not necessary.

I believe Dtek has some pre made kits that are of good quality. They use their own radiators, waterblocks and whatnot. Probably the best bang for dollar.

Some kits to stay away from are the Thermaltake Aquarius II, Aphaix Iceberg I.

Not all complete kits are crap, but make sure you get yourself a nice copper heatsink and a decent sized radiator.

I was the one that commented on the custom setup.
I don't reccomend a pelt setup for a beginner non-air cooler. Psywar will tell you there is way too much work...

But what you can do is this. Go to your local auto parts store and buy the heater core from a 1986 Chevy Chevette. Then pick up a fan to hook onto it. Then you just need a good pump, like an Enhiem. Buy a waterblock and the tubing and all needed adapters and you have a great WC setup.

Not true, I bought a D-Tek complete kit and my temps are just as low, or lower than guys who made their setup. They saved a few bucks, but it was easier on me to buy the kit.

The one thing about building a WC setup is that you have to know what your doing. You can buy a Chevette heater core, but then you have to modify the barbs to make it work right. Then you rig up a shroud and fans. It's not hard to do, but you have to know what your doing.

Choosing the right pump is really important, submersible or inline? You going t-line or rez? What block are looking at? I started off w/ a D-Tek kit, but now it's a custom kit. If you don't know much / anything about H2O setups, I'd recommend buying a kit and modding it from there.

I've heard that dangerden is better than Dtek. I'm thinking about watercooling myself and I am just wondering how many case fans i need for everything else if I water cool. Currently running 6 (not including cpu fan)

I was running 7 case fans, plus a 92MM Tornado on the CPU before I went H2O. Now I'm running only 3 case fans (all exhaust) with a 120MM on the rad for intake. 100x quieter and cools better. You don't need many fans when W/C'ing. Some guys are running fine on a intake for the rad and 2 exhaust fans.
