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.

You could probably use some PC fans, they are quiet enough that you wouldn't hear them when music/movies are playing.

If you need a really quiet fan check out the link below:

Notice at the bottom of the page is information regarding fans and fan noise. The Panaflow fans are probably one of the quietest fans you will come across. I have 4 of the 24 CFM fans in my computer and they are virtually silent.

Hope this helps.

Wow, those are some quiet fans, Errivera! However, I had just ordered two Middle Atlantic QFans (50 CFM, 30db) and one of MA's Thermostatic Controls (turns fans on/off and varies fan speed based upon temp) before I read your post. We'll see how these work out.

Interestingly, I switched out my old "plain Jane" speaker cables for MIT AVt3 cables yesterday, and the amps seem to be running hotter at the same volume level. This could be due to the fact that the MIT's are brand new and haven't broken in yet.

Thanks for all the feedback, Tom.

Eldartford-- A high-end amplifier company has gone the liquid cooled route. Unfortunately, it's CAR audio high end-- Precision Power used to make amps designed to be liquid cooled if you wanted, or convection cooled if not. Many a show car of that era had clear coolant lines with brightly colored coolant water color-coordinating with the paintjob,etc. It worked quite well.

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.
