I spent two days going back and forth with Koolance on how to plumb the damned 452x2 dual pump reservoir to run two D5s in series. Every configuration they gave me was a FAIL, so I finally said fuck this and configured it how I thought it should be configured

Getting a hellacious flow out of the two pumps (both on 5 and both jacked up to 24 volts with the Koolance voltage regulator
I'm thinking the temps are well withing tolerances for a gaming computer
Some scrennies with various temps at various loads. Ambient at 76F
