There is about 6 feet of copper tube on each of these CPU coolers...

Now I am guessing that the tubing is around 1/4" ID copper tubing, so the PD for a straight peice of copper tubing attached via 3/8" ID tubing is easy to calculate.
So, 3LPM gives 1.2m of head (116.8 mbar). 6LPM gives 4.1m (401.4 mbar).
This includes the impact from the entry to the copper tube, but not any additional turbulence impacts from the curving shape. However the tool I use already states the flow as turbulent (R=21,000 @ 6LPM)
To compare, I get the LRR G4 as having 0.912m of head @ 6LPM.
