I think our fan flow rates at EY are bogus - In order to improve temperature control Bubba and I adjusted flows on SF1 and after no response decided to turn on SF2.

Plot of the idicated flows attached - SF2 (red trace) shows 7 days of somewhat uniform flow even though we just turned it on today. Blue trace does not show expected results of adjusting pitch control as we did today.

If temperature control has improved by tomorrow we will leave the second fan running (two fans operating). Please let us know if there is evidence of increased vibration or noise due to this fan addition.

Changes were made between 4:45  pm and 5:00 pm local time.
