I installed all three blocks into the same system. The computer uses an Intel X6800 processor placed in an Asus P5W DH Deluxe motherboard. The processor was overclocked to 3.8Ghz. I used the Swiftech MCP-655 pump and MCR-220 radiator for our loop. The blocks were installed and then I ran Intel’s Thermal Analysis Tool (TAT) at full load. I allowed each water block to burn-in for 8-10 hours and made sure the system reached equilibrium by measuring the water temperature in the loop and waiting for it to stabilize. Along with the temperatures taken with TAT, I measured the ambient air temperature during the tests. Here are the results.



Swiftech Apogee

Ambient: 20.2 °C

Core 1: 77 °C

Core 2: 75 °C

Average DT: 55.8 °C



Swiftech Storm

Ambient: 21.3 °C

Core 1: 75 °C

Core 2: 71 °C

Average DT: 51.7°C





D-Tek FuZion

Ambient: 21.2 °C

Core 1: 71 °C

Core 2: 71°C

Average DT: 49.5 °C



The tests show the fuzion has an average core temperature drop of 6.3 °C below Apogee and 2.2 °C below Storm.

apogee ambient 20 deg C


storm ambient 21 deg C


fuzion ambient 21 deg C




needless to say the fuzion will get to stay in my pc...im gonna see how high i can overclock now...
