It is being temperature managed, but the exact methods depend on what the conditions and temperatures are inside and outside. All Tesla battery packs do have a liquid cooling system built into them, so they can cycle that liquid out to remove some of the heat through some radiator areas. And if that isn't keeping up enough, there is the capability for active cooling, where it can use the air conditioning system to actually chill that liquid to remove heat from the battery even faster, and that will usually involve some fans that you can hear blowing that hot air out.
