Liquid Flow Restriction

I use a CORSAIR Hydro XD5 pump/reservoir combo unit with the pump powered by a direct SATA connection to a CORSAIR HX750 PSU and controlled by an Aquacomputer Aquaero 6 XT. There is a previously calibrated in-line flow meter and Dwyer 490 Series 1 wet-wet manometer to measure the pressure drop of the component being tested—in this case that of each radiator. Every component is connected to the manometer by the way of 13/16 mm tubing, compression fittings, and two T-fittings.


As expected, the Raijintek CA360 sits in the bottom half for pressure drop across radiators given the single row and 12-way parallel split. I would classify it as a medium restriction radiator still, especially since the only ones that can really be mentioned as high restriction units are the Black Ice Nemesis GTS and its OEM offerings using the much thinner tubing. Ultimately, this particular radiator should not worry you much, especially compared to a typical CPU or GPU block.
