The fan is not what is noisy - or at least, is not the root cause of the
noise.  The cause is that close proximity of the intake of the fan to the
slots on the side of the cabinet.  You could try slowing the fan down, or,
more drastically, cut out the sheet metal of the cabinet side in front of
the fan intake (cover with hardware cloth or something else to keep you from
putting your fingers into the fan - it should be as "open" as possible).
Someone on the reflector took a pliers and "tilted" each of the slots in
front of the fan - that also might help and would be less intrusive on the
cabinet.  I don't recall how well it worked.

Hi Stan,
I have a Centaur with the typical noisy fan..I have replaced the 811's with
572B's and wondered if the 310 fan you show on your lists is the quiet
replacement for this noisy one I have.  
Thanks for any info.  Gary N5BI
