There are surgical icepacks in soft plastic bags you can place on exposed heat sinks. They keep cold for long time.

As long as the spacing is the manufacturer recommends and the equipment isn't "hot", I wouldn't be concerned about this. If you get fans, you will hear them and unless your equipment is a good distance away from the listening area, that will bug you sooner or later. Even really good whisper fans have noise. I would only employ fans if the equipment is far enough away and my equipment is getting hot without them.
I bought a small refrigerator, put my amp inside it and cut holes in it for the cables. Once the cables are through the fridge, I pack the holes with insulation that gets held in place with tape. You just have to make sure to plug the refrigerator into a power strip that isolates the outlet. And, of course, put some sound dampening material on the outside of the amp fridge so it doesn't mess up your room acoustics, and cones under the fridge and the amp both.
MOST IMPORTANT: Do not set the temp to low. If you do, you run the risk of water in the air condensing and getting in your amp.
Zd- I just tried your suggestion but it didn't work for me. My liquid cables got too cold and froze up ;-) "
You bought fake cables. The only cables that I can think of that have liquid in them are from PAD and the liquid ceramic from Cerious. They both freeze at a much lower temp than water.
I think you have taken reasonable precautions to keep your integrated cool. Even at higher volumes it still should be adequate unless you are driving low impedance loads. I have not had the concern lately about overheating since I've been using Class D switching amps which run very cool even under demand.
Zd-the ;-) is a "wink" emoticon, meant to indicate that it was said tongue-in-cheek. Sorry for the confusion. "
So you were kidding? You really didn't freeze your cables because you put your amp in a refrigerator? lol. I bet someone will try it this weekend and report back Monday on how great their system sounds.
I used to run a computer muffin fan as well. 1/2 speed as noted above. I always had it set so it exhausted the heat from above, not actually blew on the amp. Reason was so it was a convection type heat removal. It would bring the cool air up from the bottom and not the dust. I had it set about 8" above the top of the amp. I never heard it running.
I don't use it any longer as the amp now has plenty of room to breath after a new setup.
Good luck, John
