My B&K has some massive heat sinks but I still place a fan on it to draw cooling air through it. It seems each summer I need to do this. Am sure some of you do as such?
It depends on the design too. I run a fan on some amps that run hot, and can shorten the caps lives. I don't like hot transformers either, power or output. If it runs real warm, I use a muffin fan, summer or winter.
Fans? We don't need no stinkin fans! (loosely quoted from Blazing Saddles).
I live in the desert southwest, A/C works for me. My Pass monoblocks run pretty hot but Nelsons designs account for this and seem to last for a long time. I don't need or like to leave stuff on 24/7. I'd say, just be smart.

I grew up with central air and heat. The dealer that helped put my parents system in a half century ago, put muffin fans on the amp.
I too run a fan to draw heat from my B&K EX4420. My amp is the older model of your Ref2220. It draws 75 amps of current peak to peak and runs quite a bit warmer than my also 200w/ch B&K Ref4430. I would rather be safe than sorry and it also keeps my other components in my stand cooler.
