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.


So much for the power of the ramp! In the end, the relatively higher surface area of the micro fins and thinner microchannels coupled with taller fins result in a higher pressure drop than most other blocks. I can not rule out that the ramp design may have helped, and perhaps things would have been even worse without it, but as it stands, the Eisblock XPX is a medium-high restriction water block.
