I don't see what so interesting about it. How do people get it into their heads that higher flow equals lower temps. You have to get rid of the heat somewhere, and that somewhere is the radiator. Even if your flow is 10^6 gallons a second, that doesn't make your radiator any more efficient. The water is only the medium that transports the heat. The temperature of your cpu depends on the temp of the water that's in it. As long as the water flows fast enough so that it can transfer the heat from the cooler to the rad, and that it doesn't have the time to heat up inside your cooler, you're ok. Faster flowing water would heat up less in your cooler, but would also cool less in your rad. Plus that for a high flow rate, you need a strong pump to overcome the resistance, and all that produces extra heat.
I run a wc system with about everything watercooled: cpu (2GHz P4), northbridge, two hdd, vidcard. I run a Eheim 1046 with 8mm piping, and my cpu never comes over 45C, and usually runs at 35C.
