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. That said, I am not sure how old this block is since the product pages and the installation hardware mention even older Intel platforms on them. The larger but simpler cooling engine here ends up measuring with a lower coolant flow restriction than the other Granzon block as expected, and basically within error margins of the Bykski block it shares a cold plate design with. I'd classify the Granzon GAISC as a medium restriction CPU block, and it should not be a bottleneck to your standard D5/equivalent pump thus.
