Liquid Flow Restriction

I use a Swiftech MCP50X pump with a FrozenQ 400mL cylindrical reservoir. The pump is powered by a direct SATA connection to an EVGA 1300G2 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 1/2" x 3/4" tubing, compression fittings, and two T-fittings.


If you have read through the previous page, these results won't surprise you. The single row of thinner tubing hurts when compared to other brands, as well as the dual-row Hydro XR7 360. Compared to the Black Ice Nemesis GTS and Bitspower Leviathn SF (another implementation of the Nemesis LS), which this is closest to, the numbers are nearly identical, as expected. Overall, I would term this a high restriction radiator, and it can get close in restriction to even some CPU or GPU water blocks.
