Interesting observations all around. I run on 240, so there is no improvement to be gained there. As my temps rise the fans shift through the 3 levels, with the last one being very loud indeed. This is not a quiet amp, even when not in use. Perhaps I will give FT8 a try just to collect a data point, but I don't really use that mode at all. I must say I am very disappointed in this amp, what with the noise levels and the heat problems. I would have thought that running it at such low levels would have been easy, but I guess not. Next option is to look into the cooling setup as it now stands, and what could be done to improve on it.
Thanks again for the information updates.
