I think you missed one critical sentence in Stu's excellent post.
I'll repeat it.
"A few questions for you to help better understand the problem"
These are questions for YOU to think about -- they focus on the
possible mechanisms whereby the noise could be getting into your
system. It could be RF, coupling into the antenna or feedline, or it
could be baseband noise coupling into the repeater through its audio
and power supply circuitry. It could be the fan generating the
noise, its power supply, or its controller.
