Flow Rate Testing

If you don’t know how to read a pressure/flow plot then check out our guide.  Testing was done by hooking up the block under test to a water faucet/tap and varying flow throught it.  Flow was measured using a 5GPM King Instruments Rotameter, and pressure across the block was measured using a Dwyer differential manometer.  A Koolance CPU-380 block is also used here as a reference point:

980restriction

It can be seen that all but two of the blocks have similarly low restriction.  The Bitspower is as usual very low on restriction and is in fact the lowest at the range of interest.  This is similar to their R9-290 block performance.

Onwards to thermal performance!

  1. This is why XR reviews are the best on the net, the detailed disassembly is vital and very telling. It seems Bitspower has gone the Swiftech route with this generation. Simple flat plates with some grooves milled in them … No thank you.
    I saw some discussion that BP blocks are looking very EK like lately. Seems the resemblance is only skin deep.
