Liquid Flow Restriction
I used a Swiftech MCP50X pump with a FrozenQ 400mL cylindrical reservoir. The pump was powered by a direct SATA connection to an EVGA 1300G2 PSU and was controlled by an Aquacomputer Aquaero 6 XT. There was a previously calibrated in-line flow meter and a Dwyer 490 Series 1 wet-wet manometer to measure the pressure drop of the component being tested. Every component was connected to the manometer by the way of 1/2″ x 3/4″ tubing, compression fittings, and two T-fittings. Lower is better here.

I have here some entries that are GPU block, and GPU block + backplate. This was to merely distinguish each entry separately as it affects thermal performance, but of course as far as liquid flow restriction goes the presence or absence of a backplate matters not. As expected, the serial flow design coupled with the thinner 0.35 mm microchannels resulted with the XSPC Razor RGB having an even higher liquid flow restriction relative to even the old Razor which was on the higher side of average to begin with. The actual difference is not a lot in the grand scheme of things, however, with only the Alphacool NexXxos GPX being a real outlier.
