I went low tech with my D2. If you notice, there's a black box on the top right side of the Anthem. I installed one of the quiet fans that I used in my old Crown amps. The fan pulls heat off the D2 and exhausts it out to the back of the rack where 2 other fans exhaust the heat from the D2's and QSC's. The 3 fans are hooked to a wall wart that is in turn plugged into a switched outlet (I can't remember if it was a switched outlet on my D2 or Furman power conditioner). Regardless of where it's plugged in, it's in a switched outlet. When I power the system up, the fans come on, when I turn it off they shut off. I didn't mess with a thermal switch.
