Firstly they are not at all efficient at idle to low powers. Measure the idle consumption with a killwatt and consider, all that is going up as heat.
The idle losses are significant and the internal temperatures often get well past the levels for long term reliability with much of this Class D stuff.
75 to 85 degrees C (185F) is not unusual at idle on the components I circled. They basically cook the nearby capacitors. Often the auxilliary SMPS transformer runs very hot.

Whoa, that thing looks awesome! I'd probably end up spending more on adding in uber-quiet Noctua.. but that's a good stock price. Might actually order that for my network switch since it looks "slicker" than just three random fans with rubber feet laying on top.Your source to create smart growing systems with components including advance grow tents, inline fans, clip-on fans, LED grow lights, and UIS™ controllers.acinfinity.com
Some might not like this idea, but you can place 120mm fans on top of the unit to blow/suck air. I have done that in the past and 120mm sized fans running at low are barely audible even up close, yet cooled my amp by 10-15C on low. Dust can be a concern, but you just have to keep an eye on it.
These are similar to what I had, but cheaper: Fans
