Swiftech Apogee GTZ vs D-Tek Fuzion V2 As-Shipped

[Martinm210]

Thanks guys, glad it helps or doesn't help you make a decision..
Just my test though, could be different with different testing specs/methods.

I was a little concerned I didn't match swiftech's published results, but after reviewing the two I see two very different approaches. They used fixed flow rate which isn't what the pump will produce for two blocks that have different pressure drops. I used a fixed pump which produces different flow rates depending on pressure drop of the block. In addition they used a nozzle in many of the V2 results, I believe stock outperforms the nozzled setup and this is stock results.

Not to say or argue one is right over the other, just different.

it doesn't look like there's much thermal difference, however, the fuzion is slightly better when it comes to flow?

Yes, higher flow, but along with that comes about a .1C hotter water temeprature even with the big quad rad. Pump heat dump is pretty interesting, I consistently saw lower water temperatures with the more restrictive blocks that resulted in lower flow rates. The question is will the difference in flow rate add up enough flow rate gain to overcome the extra pump heat....I don't know...probably depends on the block and radiator used.. My guess is the difference is too small to measure and they are a wash..

Very interesting results indeed
So no backplate on this testing?

Yes, the as-shipped backplates were used. Both of these blocks have proprietary mounts and their own backplate. I have a hole in my motherboard tray now that allows me to switch hardware pretty easily. The GTZ was tested with the GTZ backplate and proprietary mount fully tightened with screwdrivers, and the same for the Fuzion V2 pro mount. Both were tested with the as-shipped backplates.
