Liquid Flow Restriction

I use a Xylem D5 pump with a standalone reservoir, with the pump being powered through a direct SATA connection from a PSU used only for watercooling components and not part of the test system. The pump is controlled by an Aquacomputer Aquaero 6 XT in PWM mode. There is a 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 soft tubing, compression fittings, and two T-fittings that have been accounted for when it comes to the liquid flow restriction in the loop.


I have removed all the older CPU blocks from the database, including some that were designed for the Intel LGA 1200 socket but could still work on LGA 1700 with adapters. We see that using basically the same cooling engine of the Alphacool Core 1 here in the Core 1 LT makes for both tested blocks to be within error margins of each other. As before, the relatively thicker fins and channels help reduce coolant flow restriction with the 3D-Jetplate and the larger cooling area countering it to an extent. I'd classify the Core 1 LT as a medium restriction CPU block thus and not one that will be a bottleneck to your standard D5/equivalent pump.
