If you are getting a 1.8m dP with an Eheim 1250, I'd predict something like 3.3m dP and 5.5 lpm with the CM30. Don't forget that the pressure differential across the cooling system typically increases proportional to the flowrate squared.
You're right of course, I knew there was a pressure differential increase, but I forgot it was squared to the flowrate...

The only way to know for sure is to mount the CO30 in my actual cooling loop and measure the flowrate through my Swissflow flowsensor.
