Oce Arizona 350GT Making Weird Fan Noise

[Hoeky1]

Hi all!
I hope I'm posting on the right board here.

I'm in need of some help. My Oce Arizona 350GT is making a funky noise. It goes slow and then speeds up... Any idea as to what it is? It's coming from the voltage area just off of the ground. It sounds like a fan wing is hitting something?
Should I call my tech now? Lol..
Thanks!

Your fan is about to give up. Order a new and change it.

We cleaned the fan filter and the noise stopped for anyone who may see this thread in the future!
