Running in ECO mode also should drop the temp by 10F as well.

Yes, 150F (65.6C) is hot for most animals and plants, but that's not hot at all for electronic components rated at 221F (105C) to 279F (155C).
I am not worried about my receiver's temperature as long as it does not go beyond 185F or 85C. It never did, so far.
I think it never will because of its bottom fans that start at 158F or 70C, as
mentioned. That gives a lot of safety margin for me to worry. I am happy with the built-in thermal protection.
Some even claim to notice that SS audio equipment sound best near their breaking point, temperature-wise
, but I wouldn't say that myself, because I think the improvement is caused not by the rise in temperature but the change of mode to class-A during a thermal runaway situation.
That's just my 2 cents worth of opinion anyway.
