I havn't done pressure drop testing yet, but I have been recording as tested or resulting flow rates that I get with an XSPC res top DDC3.2 and TFC 480 with my flow meter. Here are some relative flow rates to give you an idea:

D-Tek Fuzion V2 = 2.15 GPM
Apogee GTZ = 1.86 GPM
EK Supreme = 1.52 GPM

Hope that holds you over. If I can't sort out this thermal testing faster, I'll go ahead and switch to some pressure drop testing for a while. I know I can do that quickly.

Would be great if you drop pressure test it so that it can be added to the flow rate estimator. It's the only thing holding me from buying one. As we know it will perform side to side to the Fuzion and EK, pressure drop is an important factor.

I can't figure how to extrapolate your quick measurments you just posted, sadely, except it is a lot far more restrictive than a Fuzion and quiet a bit less than an EK supreme
