Recent water block (GT/Fuzion/Storm) test results...

[virtualrain]

Here is a summary of the recent Fuzion, Apogee GT, and Storm test results that I've found to date...

Notes:
- 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
- DT Values are from Core Temp to Air (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.

To see results of a MCW6002a compared with a Fuzion see post #59

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.

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.

BTW, if I've made a mistake in summarizing the results or there are other tests that can be added to the list above, please let me know. Keep in mind that if multiple runs or mounts were reported, I averaged the results of those runs/mounts in the summaries above.
