Quiet Amp Cooling Fan


Can anyone point me in the direction of a VERY quiet fan that I could use to increase airflow over my amp? I know about the Parasound Zbreeze, which is now discontinued and also too noisy. A really quiet version of something like that which sat atop the amp would be fine or even a small circular fan which could be mounted to the vertical pole of my rack might do the trick. Any suggestions would be greatly appreciated.

I am waiting for the first non air cooled systems. I imagine a remote compressor and a coolant radiator. Condensate and a bevy of other engineering issues will need addressing.
Anyway you can vent the amp by raising it a little to offer more convection? I didn't see a mention of a cabinet, but I have two McIntosh amps in cabinet and have cut some larger 3" holes underneath and above, so as not to interfere with the footing of components and have no heating issues. I had one of the amps go into protection due to heat a few years ago and since I created more air movement, I have never had an issue. I found that the natural convection draws in cooler air as the hot air escapes the cooler air displaces it and everything runs cool. And no noise!
