Hmm... Interesting.

Now all that's left is to toss in data for the FuZion with accelerator nozzles and additional base bowing and see how things shape up... :wink: (actually, this is something that I'm rather curious about, since I haven't had a chance to test it out myself yet...)

Out of curiosity, what was the justification for testing with 3/8" barbs installed? Also, by 'Dual-Die' TTV, I'm assuming that you're referring to a dual-die/quad-core configuration, no?

testing is always done with different fitting sizes. I have data for other waterblocks that have only 10mm (~3/8") fittings. I will update this soon. Anyways, fitting size mainly affects the pressure drop and "whole loop" testing.

the dual-Die TTV has two discrete dies and is suitable for Intel Q/QX series. This one is from the newer generation using a soldered TC for tcase measurement.

Yeah I'm interested to see what the accelerator nozzles do too. From what I've heard from Danny he's expecting 2C on the quad core :s

yes, but then flow rate of the Fuzion -which is it's forte, might drop below that of GTX level, negating the benefits. We also have tested another add-on tweak for the Apogee series that improved temps by about 1C, but we are reluctant to release due to increased pressure drop, and further testing is needed anyways.. I'll wait until Danny releases his tweak to release mine :mrgreen:

very informative, what differences would there be with 1/2 barbs tho? Pretty similar results?

Stephen correct me if I am wrong, but not much difference, since we adjust the flow rate to whatever we need. We are not pump limited here.

correct; in many cases the differences between fitting size/type do not appear in this type of curve. Thermal Resistance vs. Pressure Drop will show these diffrences.

Any "whole loop" test will also be affected by the fittings changes (less pressure drop => higher flow rate => better thermal resistance)

The pressure drop (with the D-Tek prototype nozzles) isn't greater than that of the Apogee GTX... (BTW, Scott, check your e-mail)
