Putting an amp in a cabinet is the wrong way to go because of the heat factor an a fan just blows dirt on the amp.Good luck though.
Amp fan cooling without dc current in the 110 line
So I just finished renovating an old TV console, modifying it by removing the TV and adding shelves to hold my gear within it. While it has vents on the sides, bottom and back, I’m sure my amp will get super hot inside. So I’d like to put a little fan in the cabinet to cool it off. But I’ve always heard those little computer fans put a lot of dirty DC current in the AC lines, resulting in noise in the amplifiers presentation.
So question is, how to avoid that.

The fan should be put on a top of the Amplifier where is the hottest to suck the hot air out. Check this out. Many different options. http://www.ebay.com/itm/AV-Cabinet-Home-Theater-Cooling-fans-w-digital-thermostat-multi-speed-contro... |
Half wave rectification puts a little bit of DC on the AC line, but decent SMPS’s are full wave and a lot of muffin fans won’t even work right on half wave. A little 5V wall wart will power one just fine. That said, putting an amp in a box that requires active cooling is a mistake. I’ve built computers with up to 6 120mm fans to keep things cool and you’re in there blowing out dust every 3 months in a religious sort of way. I’d never think of putting my F5 in a cabinet. I wouldn’t even put it on the second shelf of a rack. |
I realize that an amp in a cabinet is not ideal. However having a kid click the power button on and off but repeatedly isn't great either. Really kids and HiFi don't mix. But I don't live in a perfect world so I work with what I've got. The ventilation in the cabinet isn't too bad, just need something to give it a little extra cool. So how do the batterys work, are they always charging and the fan runs off the batterys. Where can you get one. |
