Ok I have an amd 2800 and am running a swifttech MCW5000-A water bock on the cpu. On the graphics car i am running a crappy genertic water block. The swiftech has 1/2" tubing fittings and the tube has a 3/8" inner diameter. The other water block and the radiator, which is about 3.5" x 5.5" x 1.2", use fittins where i fit the 1/2" pipe over them they seem to be a little smaller than 3/8" though. Also I am using a medium sized resovair and a 92 gal/hr submerged pump it is a Gourd micro deep-well pump model JN-134. The radiator has a 4" quiettech fan on it sucking air from outside the case into the case and through the radiator. It seems like its doing a good job and the radiator is cool to the touch. This keeps my cpu non-overclocked to about 38-40 celcius according to the mb temp sensors. Problem is the water comming out of my return line is flowing very slowly. I need help now what can i do to get better performance? Bigger pump? bigger radiator? more fan power on the radiator? :shrug: Maybe i need to shorten the lengths of my piping? I was using a very large 12" x 8" x 6" multi pass through cooper radiator with two large 5" fans and that only helped by 2-3 degrees celcius.

The picture of the large radiator is what i was using before i am now using the small internal one
