I found the A1400-8 ran warm as well but I did not put a temp guage on it. I am now running a Sunfire TG7400 and it runs noticably cooler (based upon touching the case) during use.
BTW, I returned the A-1400-8. I found the two amps very close in performance but I slightly preferred the sound and flexibility of the Sunfire especially the signal sensing "Auto On" feature. I could never get the 12 Volt trigger feature of the A1400-8 to work with my Integra. As a result was I was leaving the amp on all of the time and it was very warm even at idle. I also use and like the Sunfire's Current/Voltage Source output options for my main speakers.
Again, I liked both amps a lot but I have a history with Sunfire amps and for me the A1400-8 needed to be noticeably better ... and it just wasn't.
