Here is what Toritechie had to say about the project build.
At the start of the year I built up a nice rig:
Maximus Extreme Mobo Q6600 G0
2 x EAH3870 in Crossfire
Coolermaster 850W PSU
Coolermaster Cosmos 1000
For the first month I owned this machine, I ran with a Thermalright Ultra 120 CPU cooler; the rest of the system was also air cooled. This worked fine, and I had a stable overclock on the chip, around 3.6.
After doing quite a lot of reading on this forum, and various others, I decided to take a stab at setting up a water-cooling solution. My main reasoning behind undertaking this was to achieve a near-silent system. I wanted to include the cpu, northbridge (the motherboard is prepped for this), and both 3870's. If anyone here owns these graphics cards, you'll know how loud they are under 3d load. Oh my.
I contacted a supplier in Australia, who was very knowledgeable in PC cooling. After chatting and researching, I purchased the following:
D-TEK FuZion water block
Laing D5 12 volt water pump
Radiical Triple dual pass radiator
Two Maze 5 GPU blocks
Three Xinruilian 120 fans
2m 1/2inch ID Excellon tubing & 1m 5/8inch Excellon tubing
Hose clamps
Helicoils
Acrylic bay reservoir
Arctic Silver
It was an eager wait for the package to arrive at my house, when the fun would begin. Enough text, I'll attach the series of photos that cover the installation:
First the radiator fitting
The motherboard
Preparing for lift off
The completed system
It was FUN! I found the whole experience of setting up watercooling a lot of fun, and there were no problems during the installation.
I achieved my goals of a quiet computer, and it runs cooler. I'm running at a similar over-clock to my air, I'm currently 3.61 orthos looped stable. The couple of stress tests I've run (it's summer here) have seen the CPU sit around 45 - 50c. Please note that this is in a room ambient of about 29 - 30c. Coolant appears happy to sit around 10c above ambient at most (this is during stress tests or hours of 3d gaming) so I guess my radiator is happily able to deal with the heat.
I'm running my Q6600 @ 400 x 9, with Corsair 1333 memory @ 1280, 8-9-9-23, 1T. Vcore is 1.49. Northbridge 1.59.
I pencil-modded my 3870's, and they are currently at 925mhz core and 1250 mhz ram.
I have managed to complete 3dMark 2006 with my Q6600 @ 3.9ghz, but it simply isn't stable enough under prime for me to run that overclock 24/7.
