Listen to industrial fans on a greenhouse

Sounds of industrial fans connected to a large greenhouse. About 4 different fans in total. Some of the fans are deeper, more clunky and just basically worn out. Difficult to record and there was a significant amount of hot air blowing out of the entire fan - all directions.

I specifically noticed how different each of the sounds are outside of the obvious monster sound of the air being pushed out.

It was a really hot late summer day in the south. I forgot to get the temp inside the greenhouse but it was about 87 degrees F outside.
