How to keep my stack of Adcoms cool...

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.

An open rack is all I’ve ever used, and that obviates the open door issue. Raised a kid and neither her or her friends ever bothered my gear, and now with tube pre-amp and amp I give both a lot of space, and other than dusting things from time to time this seems to work swimmingly. I have seen an interesting thing called an Aircom S7 but you need someplace for that air to go...a back vent should do the job. The S7 claims to be quiet and self regulating and it's 49 bucks.
