Sorry for the late reply, I\'ve been busy @ work...
It\'s been a while since I surfed around for step-by-step guides to watercooling, but again, I\'ll try to take you through the basics. Start with the pump. Depending on what kind of pump you\'ve got, you\'ll either have one or two hose-nipples standing out from it. Check the manual to find out which one is outgoing, and if you\'ve got two, which one is pumping in. I use a pump with only one, so it\'s sitting at the bottom of my water reservoir.
The next thing you do is to put a hose from the outgoing pump-nipple to your cpu waterblock. Then a new hose from your waterblock to your radiator. Another one from your radiator to your water reservoir. Do NOT mount it in your computer yet. Plug in the power of the pump, and let it run for a couple of hours. Check every now and then if you\'ve got any leaks. These will normally show up either in the hose/nipple connections, the waterblock (which is normally screwed together from two pieces) or the radiator. If you\'re planning to put the whole thing into your computer, you\'ll want to make sure that there are absolutely no leaks whatsoever.
When you\'re absolutely sure that you have no leaks, after running the thing for hours, run it again. Let it rest for a little while, and run it for another hour, just to be sure.
After going through these steps, you\'re just about ready to mount it in your computer. Put the whole thing in, be careful when mounting the waterblock on your cpu, and start the pump. When it seems to be running smoothly, boot the computer and hope for the best...:-)
Good luck!
