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.

Ive seen alot of telecommunication racks use a passive ventilation system that works rather well, seeing as how delicate the electronics are.

Take some aluminum plates that will fit snug in the rack flush side to side. bolt the front of the plate about 2 inches above the the front of the adcom unit, and the rear of the plate about 4 inches above the unit. (doesent have to be exact, but you want it sloping backwards to pull the heat away.

when the heat rises it will be pushed out to the back of the cabinet and away from the gear.

Of course, you will need vents in the back of your cabinet for this heat to escape.

This method works better than people would expect.
Like i said, this technique is used in alot of communication racks with hundreds of thousands of very delicate electronic circuitry.

I think this passive method works better than the fans do, as the fans will either pull from above or from below, but either way whatever gear is at the end with the "Pulling" fan will get plenty of heat.

You could always couple this with a single fan placed at the bottom of the cabinet and have it blow up and slightly towards the door, providing cool air in the front that will help reduce the heat as well.

Careful with the heat dude.
I fried 2 dvd players because the reciever i was using was such a powerhouse it generated alot of heat.

personally i like open air racks the best. less to worry about. lot more dust though

Peace!
if you DO decide to put a fan in to suck the air out, you might want to locate it in the middle of the back instead of the top. cause then it will pull all the heat to the top

Im not suprised that it was a car manufacturer that did that. Summer time the trunk of yer car is gonna get hotter than hell, add on 1000W mono amplifier driving a 4-2 ohm load, yer talking about brimstone fires of hell

Other than roasting a few dvd players, ive never really had heat problems in my home gear, my car gear on the other hand, now that has a tendancy to overheat pretty quick.
I definatly think it is a bigger concern in car audio.
