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.


We went over the various factors that contribute to the liquid flow restriction of a CPU water block and how things end up potentially lower or higher on the Bitspower Touchaqua Summit MS OLED. As it turns out, the combination of all those factors, and in particular the relatively fewer fins in a smaller area compared to most other blocks in the test database, lead to its placement towards the lower side of average here, which is a good thing on its own—this block can be classified as a low-restriction CPU block thus and will not pose a challenge to most pumps typically used in PC watercooling.
