No this shows up when you really fully load them and the fans can't keep up. Most people never do, but then why buy the Max?

AFAIK it’s only something that happens under sustained heavy load. The 14” Max should still outperform the Pro for shorter tasks but I’d reckon few people buy the most expensive machine for such use cases.

Personally I think that Apple should not even be selling the 14” Max when it has this defect.

But if you buy a Mac Studio today, you have to choose a M4 Max or a much faster M3 Ultra.
