Adventures in
Water Cooling


After I built my new system I realized I had a great problem. The heat produced by this new P4 was huge. During testing I ran Prime 95 (a stress test program) running twice, one for processor 0 and one for processor 1, for only about 5 minutes to test the heat problem out. At the end of those 5 minutes my processor temp was around 151F or 66.1C. This is very high and plus making it worse was the stock Intel fan. At high speed this fan sounds like a small plane. Thanks to the internet and the many great reviews I read from I would have to guess 50 or so different sites. I decided that water cooling was the way to go. I purchased most of the parts at Danger Den. Their water pumps and water blocks seemed like a good choice and also were recommended by someone I talked to at work. So with a recommendation and a lot of reading completed I purchased my parts.

First on the list was the radiator. My case, the Cooler Master Wave(Limited Blue Edition) was too small to use a pre-made radiator that fits in the back of the case. So I purchased one from Summit Racing(pictured below).

FLX-4110 Aluminum/Copper, 5 in. x 12 in. x 3/4 in.

After receiving the radiator a few days later it was planning time. The first problem was where to put it. This I solved easily. At the bottom of case was room to mount and enough space for the pipes. Then after talking with some people, it was decided that having a box that was on the back of the radiator that collected air that was blown trough the radiator and then use a product I had seen at work to exhaust the hot air out the top of case that already had a blow hole. The product I found was an air duct. Its actual purpose is to install on your cpu fan as blow or suck air from your cpu out and provide better cooling. So after getting a few ideas I went to see my grandfather who is a machinist. He helped me build a box and mounts for the radiator and cut the perfect holes in the side of the case. This is what we came up with below.

After building the box we found that we had a problem that we missed during planning. After installing the box and screwing it in I noticed that the box was flush with the graphic card fan. So an easy solution was to cut a hole in the box that matched the graphic card. This helps the graphic card by getting it cold air. After running this setup for a while it has lowered the graphic card temps by about 5C. Which is better then nothing.With everything built this is how it looks in the case.

After getting the radiator and box done it was time to decide on a reserivor and water block. For the reserivor, I starting by looking at one that was a bottle type. Although this would have been easier it would be left outside the case or not fitting right on the inside . So I went with the drive bay design from Danger Den. The Danger Den single 5 1/4 drive bay.

Since the last picture has the fans in it. Its on to the fans. The fans are Silver Stone 120mm speed control fans. I purchased the fans from Micro Center for $14.99 each. The fans can be found here. The specs on the fans can be found on the web site above. Here is a shot of the back side of the side panel.

The reason I decided on these was that they seemed well made and are very quiet at low RPMS below 1250rpm is almost silent. At full speed it sounds like a small vacuum cleaner. Even at low rpms the temps did not change, so for now the amount of air and noise level is perfect.
