Liquid Flow Restriction

To make things simpler, I have decided to use a CORSAIR Hydro XD5 pump/reservoir combo unit rather than a discrete pump and reservoir. The pump is 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.


Not bad at all! The 14-way split of relatively thicker tubes means this single-row core hangs with the big boys. Coolant flow restriction is the lowest of the thinner radiators to date, which is quite impressive. I imagine the wall thickness of the tubes is also on the lower side of average owing to the lack of any alloying of the tubes, but regardless, this is firmly middle of the pack for everything, which is very good for the 30-mm-thick radiator it is.
