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. 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 CORSAIR Hydro XC7. As it turns out, the combination of all those factors leads to its placement being slightly better than average in the updated test database, which does have fewer participants at this stage compared to what we had with the Hydro XC9, but it will fill up over time as it takes over. I would generally classify the CORSAIR Hydro XC7 as a low-medium restriction CPU block, one that will be of no real issue to work around if you go with the popular Xylem D5 or DDC pumps.
