Passive vs active cooling for Up and Up Squared

Options

I'm still shopping an Up and/or Up Squared and, being new and still browsing the forums, how essential is active vs passive cooling on the Up and/or Up Squared, presuming regular medium use to short term high loads? The fan is optional in purchases so I'm unclear the thermal requirements.
