A number of readers asked that I do a test with the GPU and Chipset waterblocks in place and compare these results to the system with only the CPU waterblock. The following resulted:
The Test
Asetek's WaterChill Power Kit was tested using the CPU Die Simulator; I ran the fans at 7 and 12 volts.

CONCLUSIONS
Adding the additional blocks marginally degrades performance, not enough to really make a substantial difference at the desktop. One reason that the difference is so slight is that the waterpump has enough "overhead" so that the added pressure drop minimally impacts performance, as well as the radiator. Systems with lesser waterpumps will show a much greater performance hit.
