The lack of cooling in the air is definitely something that should be fixed
That's not really the point of the MacBook Air. The Air lineup has always been about doing quick, bursty tasks effectively (email, web browsing, word documents etc). Apple Silicon chips have gotten to the point where fans are not necessary to achieve this objective, so Apple skips a fan in the Air models to help better differentiate the various MacBook models.
The 14in MacBook Pro with M3 chip is essentially just a high-end MacBook Air, as it carries most of the same limitations minus cooling.
You could have just said you didn't know what you were talking about from the get go.....
