The truth about DDC's

[zanzabar]

Alex, believe it or not, according to my pressure gauge...I only get ~1 ±.2psi with the flow meter @ full flow.


Pump________Total head pressure (PSI)_______Max Flow (l/m)__________RPM's

3.2______________6.2 ±.2____________________~11.2_____________4470 ±30 (with a very small spike to 4530-4560 when full restriction was applied)

Your higher RPM's may be due to a higher amp rail PSU than what my PSU is. When I did the video I linked earlier in the topic...I had used a 550W Antec NeoHE with a bad 5V rail, I later tested the 3.2 with a much lower watt PSU (220W Shuttle unit) and the RPM's dropped by 1k....

i have a 750tx, and when i had just a pa120.1 and a dtekv2 it was up there now with an mcw60 added its a 4050-4100

thx for doing the test, even though i missed it for a month and a half
