Update: Quiet fan

I got the new fan today. It's marketed as a "low speed" quieter fan. It should be a drop-in plug-in replacement. I'll post back on the results.

The new fan is installed and boy what a difference. The original fan was like a blow dryer on "high". The new one is like a table fan across the room. Noticeable but not really objectionable. Since I don't do any listening to quiet orchestral works, I can live with it :)

My Ashly FTX had a factory AC fan that was noisy. I replaced it with a super quiet DC computer fan and just used an ac adapter to run it. This eliminated any motor activity from the amps power circuit.

  "eliminated any motor activity from the amps power circuit", interesting. I saw some fans that came with power cords but when I saw this one that the factory wiring would plug directly into, I went this way instead. On the BGW, the fan is wired to the AC input. If there's a fault that won't let the amp play and it doesn't trip the circuit breaker, the fan still spins. I wonder if externally powering the fan like you did would affect the SQ the way the BGW is set up?

    A quiet fan is a dead fan.

      On the contrary. There are a number of computer fans out there that move a surprising amount of air with little to no noise.
      
      I also think about the cooling in a pro amp. The fan has to cool the amp when it is being driven very hard for long periods of time. In a home audio listening environment that isn't usually the case. So even using a fan with a little less cfm than a factory unit should still work out ok.

        That did not turn out to be the case for me. The fan works hard when driving the bass panels. I would not take down the air displacement rating to get more quiet. I already had the amp burn out its own thermal control circuitry and go in for repair.
