Corner Station Fans (Attachment 1)

A few of the CS fans seem to have gotten louder/noisier since this past Tuesday's (07/18) maintainance (vertical line on Attachment 1) (In the alogs it's only noted that the outstation fans were greased, but due to the timing of when the CS fans seemed to have been turned off/back on in succession on Tuesday, I believe they were also worked on?)

• MR_FAN5_170_2 (Attachment 2- Clearer view of vibration after Tuesday, Attachment 3 - Zoom in of last ~10hrs)- Used to stay around 0.1 but over the past few days has had multiple-hour stretches where the values increase before going back down. Every time this has occurred, they go up to higher max values. As of now, they have been jumping up for the past 6 hours, hitting a max value of 0.5.

Outbuilding Fans (Attachment 4)

• MY_FAN1_270_1 (Attachment 5) has been giving high readings since it was turned on on Tuesday. Currently oscillating between values of 0.60 and 0.68. Exceeded 0.8 yesterday (07/20).

Other observations - low/no concern

• MR_FAN2_170_(1&2) have been noisier since Tuesday, and are the loudest they've been since the start of O4, but max values are still only around 0.25
