keyword=Adjusted Loop Fans and JT ValvesIn anticipation for running on H2 Loop2 target, I ramped down the fan speed on Loop1 from 60Hz to 24Hz (in 2% steps) and then ramped up Loop2 fan speed from 24Hz to 48Hz, all while I appropriately adjusted the JT Valves. Our Cryoflow draw is a little bit less now ... decreased from 14g/s (while running on D2) to about 11.8g/s (running on H2).
