How to keep my stack of Adcoms cool...

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.

Slappy- it might be more of a concern in Car audio based on the "mobile environment", but I can see home audio geeks, er I mean cool guys like us, really getting into it.

Hell, you could have an amp that was warmed up to operating temp by warm water and end that annoying 20 or more minutes you have to endure of less than perfect highs or grainy vocals when you get home from work. You'd switch on your amp with it already at a perfect temperature for optimum listening...

As the evening progressed, the system would convert to cooling the water. A simple Peltier device could both heat and cool the water as needed, and as controlled by a simple thermistor. With the size of amps nowadays, and the ton of "aesthetically pleasing empty space" many contain, you could put the whole sealed pre-heating / cooling system inside the box. Carefully designed, the water could circulate via convection currents and wouldn't even need a pump. How cool (pun intended) would that be?

I think Eldartford's onto something, and the resident rocket scientist is probably in his laboratory as we speak converting an amp to liquid temperature control.

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.
