Corner Station Fans (attachment1)

All fans are looking good with no concerns, with MR_FAN5_2 being very variable in noise level (as it usually is), and MR_FAN5_1 being the loudest at just below 0.4.

Outbuilding Fans (attachment2)

All fans are looking good and are well below any noise level that would be of concern to us.

Notes:

- Monday night, 08/29 at 6:13UTC, EX_Fan1 turned off for a minute before a power glitch(coincidence??) turned it back on (attachment3).

- 09/01 16:39UTC, something similar happened with EY_FAN2 (attachment4), although this one is probably related to the work that Randy and Tyler were doing at EY around that time(72628)
