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. Since it is still clearly compatible with LGA 1700, and even the yet-to-be-announced LGA 1800 apparently, I figured this certainly deserves testing even ignoring the part where this is my first Granzon block review too. Despite the smaller surface area occupied by the fins and the relatively simpler cooling engine, the significantly thinner microchannels—the sections that the coolant is forced through—result in a higher than average pressure drop across the Granzon GAI0.1 block. I'd classify it as a medium-high restriction CPU block, it's worth accounting for when planning for the pump to be used in a loop that has this block and other restrictive elements in it.
