"I water cool my computer by placing the mother board and components in my bathtub. I fill the bath tub with ice, salt, and water. My hard drive is currently in my toilet. I suggest rinsing the processor off, and then drying it in the microwave, before you put it on the mother board. For added effect, I turn my hair dryer on, and drop it in the tub full of water and computer. The extra voltage helps speed the processor up. The keyboard is grouted to the shower head, and the monitor hangs off the towel rack. Currently I have a 5mhz 8086 clocked to 200 Terahertz. Asside from the occasional underwater fire, it doesn't seem to mind. I do recommend that you ground yourself to the hot end of a High Voltage power line, before you get in the tub. Also note that welding goggels may be necessary, as the processor is near the Nuclear Fusion temprature, and may emit up to 10megawatts of pure UltraViolet radiation. You may experience the occasional rip in the time space near the processor, if this keeps occuring, lower the clock speed by 50 Terahertz. On rare occasions, black holes may develope near the power supply. UNDER NO CIRCUMSTANCE should you pass the event horrizon of the black hole. Do not turn the power off , as this may collapse the universe into your bathroom. There are no known workarounds for the Black Hole problem." - Unknown quote

My current system:

Abit NF7-S rev 2.0 motherboard

CPU XP1700 (1460 Mhz), T-Bred core, DLT3C JIUHB Core @ 2300 Mhz

Radeon 9600 Pro

Cooling: Homemade CPU and North Bridge block, SpringFlex Tubing, modified Eheim 1048 and a heatercore from a Toyota Camry ('94 I think)

I soldered the barbs on myself:

This is my previous system with same case, blocks and radiator but with an Abit KR7A-RAID motherboard:

Previous waterblocks I have made:

Update August 2005

After years if watercooling I have decided to move to something more practical. This wasn't really possible before but in the last couple of years cooling companies have realised there is a big market for silent solutions so there are quite a few good products for people concerned about noise now. The product I chose was the Thermaltake Sonic Tower. This thing really is a big-ass mutha-fvcka. It weighs close to 700g and is about 150mm tall. It uses the AMD mounting holes which fortunetly I have on my old motherboard but I would be hesitant if using clipped to the socket. It had mixed reviews but I was pretty sure I could make it work and its so cheap too.

Any, pics:

Its massive.

The power supply is an Enermax 430W one that I modified with a 120mm fan that is near silent. I cant hear it when its under my desk at all. I have an 80mm fan at the rear, an Vantec stealth fan running at 7V, which is VERY quit too. So how well does the Sonic Tower cool my CPU?

I am using the same CPU as above running at 2000Mhz @ 1.45V. Average idle temp is 40C. When I'm using my PC for email and browsing it sits on about 44 and when playing a game etc it gets to about 48. I am very happy with these temps considering it has no cooling atcually on the CPU heatsink and the two fans I have are VERY quiet. This is much quieter than the watercooling setup I had.

I also suspended my hard drive in rubber bands which cuts seeking noise down massively:

So now I am very happy with the noise (or lack of) that my PC produces and I am moving on with other projects!
