Does that really work? I would expect the fan to kick in based on temperature, not cpu frequency?

Or do you mean restricting clock speed based on temperature?

the fan turns on because the cpu gets hot, the cpu gets hot because it’s doing more work, slow the cpu down and it does less work. downclocking to keep the fans from kicking on is the same thing as thermal throttling, just earlier
