Liquid Flow Restriction

I use a Swiftech MCP50X pump with a FrozenQ 400mL cylindrical reservoir. The pump is powered through 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. Every component is connected to the manometer by the way of 1/2" x 3/4" tubing, compression fittings, and two T-fittings.


The relatively higher surface area of the micro fins here and thinner microchannels with taller fins ultimately result in a higher pressure drop than on most other blocks. I can not rule out that the ramp design may have helped, but both the original Eisblock XPX and this Aurora Edge version are medium-high restriction water blocks, with the latter being the most restrictive block so far in my updated test database, outside of the previously tested Eisblock XPX 1U that was a one-off entry test.
