Fans are good in prolonging the life of the equipment, bad in generating 
noise, adding to cost and consuming power. Properly designed, most home 
gear has no need for a fan, though it requires some attention to air 
flow. (Units with fans are less critical but have some vulnerability as 
well.)

If the noise is bothersome, either put the amp where the noise is less 
significant (tough to do with a receiver which is why most quality 
high-end gear separates the tuner/preamp from the amp) or get a quieter 
fan. If the design is sufficiently constrained, you may need to replace 
the receiver to get a quieter fan.

So if you really have an amp not a receiver, move it. If you can't/won't 
do that, see about replacing the fan with a quieter one. I would not 
blame the fan for doing its job.
