It sounds like you’re talking about a MacBook Air as a generic MacBook, whereas in fact the MacBook is it’s own distinct line of computer, debuted in 2015. It indeed does not contain fans.
Macbook debuted in 2015? Macbooks were first released in 2006. Mine is a Macbook Pro.
Obviously newer models are different from older models, and Air models probably don't have the fans that Pro models do, but the claim that Macbooks don't have fans is a bit too broad to be true.
