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.


Despite what seems like an under-utilization of the cold plate space, the thicker than average microchannels (especially for a 2017 CPU block) coupled with the relatively large microchannel area help keep the Bykski FOUR a high-flow, low restriction CPU waterblock. This is good news for those with pumps that do not have a lot of head pressure as CPU blocks tend to be the most restrictive element in a watercooling loop.
