Swiftech Komodo-NV-GTX9 Review – Swiftech’s Full Cover GTX 980 Water Block

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:

It can be seen that all but two of the blocks have similarly low restriction.  The Swiftech is as usual among these “good blocks”.  This is similar to their R9-290 block performance.

Onwards to thermal performance!
