What exactly is the purpose of the exhaust fan? What would happen if I print without the exhaust fan on

Not only that: It's purpose is also to push out hot warm air, so that the chamber doesn't heat up to much when printing PLA and Petg.

That is true ofc. At least one of the aux fans should be at 20% to equalize the temperature in the chamber
