Nice to see all the support in this forum.
As to the debate on testing, I don't think there will ever be one clear solution on this. To be honest, I would like to see an overclocked AMD system (maybe at 2.1v) with just standard watercooling stuff. Having something that generates gobs of heat to test the system isn't realistic. As is using a constant flow of the same temperature water. Both of these would give a best worst/best case scenario and nothing real world. My Ideal test setup would be something like this...
1. A system with a AthlonXP overclocked and overvolted which should generate some good heat (as well as performance
).
2. Installed in a common case type (Antec would be good I suppose, but really any good Mid-Tower should work), with standard fans installed.
3. In a room where the temperature could be monitored, but with the case closed up (not opened which could skew the numbers).
With this setup you would have a fairly common setup (similar to the various Heatsink roundups you see done on the various websites).
Now you could setup a baseline system (say a Maze3, with 1/2 ID tubes, connected to a heatercore, and an Eheim 1250 pump).
Block Testing:
Once you have the baseline numbers, you simply can swap out different Blocks to test them with this setup.
Pump Testing:
Once the various blocks are tested, you could change the pump to a 1048, or 1046 and perform the tests again (which would give you a good baseline on pump performance).
Tube Testing:
Now simply change the hoses to say 3/8 ID (or smaller) and do the same tests again.
Radiator Testing:
Just as with the other tests, you could just change the Radiator (BIX, BI, DangerDen, Heatercores, etc), and record what the benefits are for each one.
This is my opinion, but I think this test would be more realistic to a lot of people. Just a thought, what do you all think?
