Thanks for all the compliments!


I have two questions for anyone following this thread...comments/opinions appreciated.

1. What's the best way to eliminate the flat spot on the run from the FuZion to the MCW30?

I'm using 1/2" Primoflex, which does work pretty well. As noted elsewhere in the thread, I did already shorten the run by ~2" which helped, but I think going further than that will make it worse. The other option is to make it a lot longer, which I'd like to avoid.


2. According to Martin's Flow Rate Estimator, the loop should flow about 1.08GPM at 4.5PSI with my D5 vario on setting 5. That plots into the "good" area on Martin's graph, but is that going to be enough?

During the last update, I posted pics of the blending I did to the outlet port on my D5, which should help flow slightly. For comparison, Martin's estimator shows a DDC 3.2 with Petra's top flowing 1.16GPM at ~5PSI. Two D5's (setting 5) in series would get it up to 1.5GPM @ 8.4PSI, two DDC-3.2's w/DDCT-01s tops would be 1.6GPM @ 9.4PSI. I'm going to run it as it and observe performance, but even assuming it performs well, what could I expect to gain with a .5GPM increase in flow?


I happen to be doped up after some surgery I underwent this morning, so if I missed something or I'm not making sense...well that's probably a factor.


Edit:

Errr...probably should have included the final loop config:

EK Multioption RES150
Laing D5 Vario, setting 5, outlet transition blended
Swiftech MCR320
Coolingworks CoolRad 22T (used MCR220 in Martin's FRE)
EK FC-8800 (G80)
Swiftech MCW30
Dtek FuZion, washer and 5.5mm nozzle

Pump -> MCR320 -> FC-8800 -> CR22T -> FuZion -> MCW30 -> RES150 -> Pump

FWIW - I'm running Scythe S-Flex SFF21F fans (1600RPM @ 12v). They'll be controlled by a Sunbeam rheobus, and I expect to keep them around 9v, but maybe as low as 7v.
