What's that noise?

Up front, and I am talking up near where the generator is located I can hear what sounds like a electric fan blowing. Not a little fan such as the dash ac/heat fan, but more like a large electric fan designed to keep a motor cool. I can hear it from the cabin as well as outside.

I hear this when the engine is running and the generator is off.

Anyone care to tell me what I'm hearing, or take a good educated guess...LOL

Thanks in advance.

This is on a 2018 Berkshire XL 40B

I would assume engine cooling fan....except Iím pretty sure these have a hydraulic drive/viscous?? fan. Electric cooling fan for condenser? On old GM vehicles anytime the key was on the a/c blower fan ran on low for fresh air...any chance?

It is the a/c fan outside. You will find it by the front axle.

Thank you everyone. I knew it was a noise that I had on my other pushers, but for some reason I just couldn't make myself believe that it was the AC fan.

Let's chalk it up to an old age brain flatulence.

Again, Thank you!!
