Water block (GT/Fuzion/Storm) test results...

I thought this might be useful for those looking for a watercooling upgrade.

- If multiple mounts were done and results provided, I've indicated that and averaged the mounts/runs.

- Review the test methodology details and test result details by clicking the links

- All values are in deg C unless otherwise stated

- Quad core load temps as reported by core temp or TAT were averaged by the testers and sometimes the difference between cores was as much as 10 deg C. According to Philly_boy lapping seemed to reduce difference in cores significantly.

H20 Frag-monger (Apogee vs. Storm R2 vs. Fuzion)

CPU: X6800 OC to 3.8GHz

WC Gear: MCP-655, MCR-220

Test SW: TAT

DT Results: Apogee = 55.8, Storm = 51.7, Fuzion = 49.5

Winner: Fuzion beats Apogee by 6.3 and Storm by 2.2

My conclusions so far:

Given the fact that all tests by the same testers varied by up to 2-4 degrees just by remounting or doing another run and the fact that all blocks are typically within a few degrees of each other (and often much less) I would say it's impossible to declare any block definitively superior to another so far.

Given this, I think any testing without multiple and equal number of remounts for each block can be very misleading. For example, Nikhsub1's tests show that the Fuzion could win by 4 degrees or lose by 1 degree to the GT depending on which mount and run you used to compare. With the mount making as much as a 5 degree difference on blocks that typically only differ by a couple of degrees it makes drawing conclusions from limited runs/mounts dubious at best. :slapass:

The only thing that everyone seems to agree on is that the Fuzion flows significantly better than any other CPU block giving it a distinct advantage in multi-block loop performance.

Interesting results. I always wondered if one waterblock would dominate when it came to watercooling double die CPUs. The small temperature differences between the blocks is reminiscent of single die CPU waterblock head-to-head results.
