Denon Mono block amp running hotter than the other


I have a pair of Denon 6600A mono blocks which one is cool and the other quite warm but yet sound the same and have what appears to be equal volumes-any ideas what may cause this should I be concerned?

I had a similar situation once with a Classe amp where one side was much warmer than the other. I had the amp's bias adjusted and the temp difference was gone. As far as I could tell there was no sonic difference before or after bias adjustment.
