One time at a party the heat sink fins were getting hot to the touch. Like you did not want to leave your hand on there hot. Well this was winter so we put some snow in a plastic bag in between the heat sinks. Another time at a party suddenly no music. When I go to investigate there's a bunch of guys scratching their heads, trying to reassure the poor owner, nobody really knowing what to do. I said it got hot, protective relay, put it out on the deck and in ten minutes the winter air will have cooled it down and we can party on, Garth. Which we did. So scientifically speaking its best to do your hard rocking amplifier over-heating in the winter time. |
Ideal would be the fan that forces air from bottom to the top of the heatsinks. Any air speed would be much better than cooling by convection only. There are very quiet slow fans available, but positioning them might be difficult. My amplifier runs only warm, but lowering temperature always extends life of electrolytic capacitors. Some of the laptop coolers are advertised as quiet, but it might be still audible while fans are likely positioned in wrong places. I'm thinking about building 1-2" tall base with quiet fans in the proper location and side air intakes. Good, easy home project. |
I have a Parasound 5 channel amp in my home theater system. There are only a few inches between the amp and the shelf above. I use one of these with front exhaust. It works great and is very quiet. They also have models with top and rear exhaust. https://www.acinfinity.com/component-cooling/component-fan-systems/aircom-s10-receiver-and-av-component-cooling-blower-system-front-exhaust-17/ |
