I finally got my Storm G4 system setup in the beginning of June (well, I guess it's been a while
), anyhow, I was looking at the performance curves to approximate the flow rate of my system. I noticed, however, that the curves are based on a system that consists of a Thermochill HE120.2, where I have a 120.3. How much more resistance is there with an HE120.3 vs. a HE120.2?
