So I have been running 2k RPM for 12 hours a day, and I was thinking of changing it to 24/7 running at 1500rpm, any need or specific reasons why I should? I know there are 2 factors that may need to run at a specific flow which is my heater and IC40. What I have setup seems to meet the needs for those 2 components. I will be shutting of my heater soon as the weather will be warming up here.
