Finally got my hands on this famous radiator. A special thanks goes out to Danger Den for providing me the radiator to test with.

With all the talk I've heard about reducers around the G3/8" threading, I took this one a step further and tested with two configurations. One was with EK's G3/8" barbs that the good folks at watercoolingshop.com provided to me. They also sent me a set of G3/8" to G1/4" reducers so I could hook up my favorite Danger Den Fatboy barbs on the radiator and test that as well.

Here is the full scoop on my site with more details and pictures:

And the executive summary below:



And the two tests compared to the Thermochill published results as well as the MCR320 and prototype Feser 120.3.



My results fall inline with the published, actually thermochills published results only went out to 2.0 GPM, so anything beyond that is interpolated from a trendline. The EK barbs were very very slightly more restrictive, and the adapters with Danger Den's Fatboy barbs was slightly less restrictive. The large ID and chamfered edges of the Fatboy barbs as well as the reducers gave it a little edge here.

In the end, I've basically just confirmed the PA120.3 is still King of low pressure drop for triple rads.

Now we just need to get some good thermal testing done..

Cheers!
Martin

Nice..Thanks for the testing...The 3/8 to G1/4 didn't make nearly as much difference in flow as i would of liked it to ......But really G1/4 is just about as big as the tubing ID anyway...With the thermal testing it might make more of a dent...

Very nice to know, it would be great if you could get your hands on a 360GTX so you could add it your table .

I have a pair of 480GTX's now...working on testing those.

Are you going to do some thermal testing with that pa120.3 and X-Changer rad?

I had to send the Feser X-Changer back, it was a prototype with a quick turn around only. If I get a copy of the final production run I will though.

I need to do some figuring on my heat load values. I picked up one 300 watt aquarium heater today, and I've got two more ordered. My variac willl allow me to control one I think from 0-300 watts, so I should potentially have the ability to load a radator with anywher from 20 watts (Pump only) to 920 watts with the combination of heaters I'll have soon.

I just need to figure out my testing box and start wiring senors. I also have a few fans I'm going to need to pick up before I'll have everything.

I always love your testing Martin... the information is invaluable and no one else does testing like you do thanks a ton

I second that, your testing is most definitly invaluable. I can't imagine where the water cooling community would be without you.
