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. This is one of the rare exceptions since I think it's an older block that Bykski is still selling with the updated backplate, but since it has not been reviewed before we will continue to include it in subsequent reviews. As it stands, we see that the slightly smaller cooling engine coupled with the thicker fins and channels results in a relatively low pressure drop across the Bykski CPU-XPR-C-I block. This will not be a bottleneck to your standard D5/equivalent pump thus.
