I run a Bryston 4BST in an open rack, but it still gets hotter than I'd prefer. Picked up a high quality 12vdc PC fan for about $15 on Amazon.....Noctua NF-S12A FLX........made in Austria.............very quiet, 18db, barely hear it with no music. Built a little cage for it, set it on top of the amp, problem solved, amp stays only slightly warm now even when pushed hard..............Agree on a closed cabinet being bad........45 years in high end electronics......nothing kills electronics faster than heat. My vote is for fans, probably two since you have 3 amps.........How you hook them up will depend on the details of your setup, but you HAVE to get the hot air out and cool air in.......or you'll be buying new gear pretty quick.
How to keep my stack of Adcoms cool...
I have three older Adcom amps in my entertainment center (two GFA-555II's and a GFA-2535), and predictably, they generate a good bit of heat. I usually leave the door to the cabinet open, but I would like to be able to close it sometimes, as it gets in the way of my speakers, somewhat, when it is open. My thought was to install a couple of cooling fans (one sucking air in, and one blowing it out), but I am somewhat concerned about the noise. Does anyone know of any very quiet fans, or of any other tricks to keeping your amps cool?
Thanks, Tom.
