Has your Anthem ignited yet, Michael? All the ADAs I have run cool even with 2400W peaks.
Not yet, but I'm not using ANY of the amps. I have an external ICE base amplifiers. - and they run cool.
I did get my T8 cooling fan. Pretty slick device. I can set it up to start pulling air at any temp or fan speed. I have not had time to watch a movie though, so I don't know if the Anthem's fan will run yet.
I might also add that some of the guys at AVS reported the MRX fan would run, even when using external amps, so this is not a "hot amp" thing, but a processor thing. My MRX fan only came on during movies with multi-channel sound processing.
