This article (about perfume storage, but I presume the same applies to A/S and cologne), suggests that you are right. It states "a consistent temperature of between 60 and 70 degrees is the best option", and that it can be kept in a fridge.
My Floid Vigoroso has gone slightly cloudy. It has lived at the back of my splashes cupboard with Floid Suave in front of it and Floid Black in front of that, neither of which have gone cloudy. All three survived last year's little heatwave. Everything else in that cupboard, including vintage is all fine. Curious.
I keep all of my EDTs and aftershaves in a cool, dark cupboard. I think that should be cool enough to keep them in mint condition. It always worries me whenever we have a heatwave, though. I don't want all of my expensive fragrances turning to crap, and then having to be thrown away. It would be a waste of a lot of money.
Wife has a bottle of Issey Miyake that she bought to wear on our wedding day (20 odd years ago), just sat on her dresser exposed to direct light and heat

I have some Tom Ford edc that went off, some floating bits and a bad smell.
I also cleared out my fathers house after he died, he had a dozen or so aftershaves in his bathroom cupboard, some were 10-15 years old but all were unusable.
Sorry if you don't like to hear of the experience of others.
