is the danger den maze4 w/cooling kit enough for my system? the cpu wil be o/clocked 4 ghz up. Also, can u like mix and match rads and blocks from other brands?
Yes. A kit simply contains the stuff you need in one package. You can also roll your own kit. I'm no expert on watercooling, but both Swiftech and DangerDen are very solid performers from what I have seen in reviews. The only thing that could be a problem is if you try using barbs with different sizes. You just want to use all the same size tubing or you can slow things down. If you want, say a Black Ice 120mm rad, you can use it to replace one in a kit. Outside of keeping the same tubing, the only other thing you'll want to do is assemble the kit and make sure you don't have any leaks before installing it in the case. Pure water does not conduct electricity, but the impurities in it do, which is why you'll use distilled water. Any additives (like antifreeze) will put some impurities in the water, but that's to prevent things from growing in the water system.
thanks for that BB. two more things, what is "bleeding a system" and what are the chances of a kit leaking?
Bleeding is draining the water from the loop. When setup correctly, the chances of leaking are slim, but that's the key. Hence why you would want to do a run before installation. If you use some silicone grease like in plumbing applications, the parts will slide in together more easily, and help prevent leaks.
