The Thunderstroke engine is air and oil cooled.The heads carry 60 lbs oil pressure and the 2020 & up have a larger oil capacity.I live in Arizona and my 2022 111 Springfield is the coolest running of all the 3 Thunderstrokes I have owned.My 2017 was a 116 BBK and ran quite a bit hotter than any of the 111s.Bigger,more compression=hotter.
That being said,When I worked for Indian Motorcycle in NW Arkansas, we had a customer start his Thunderstroke one winter day.He left it in the garage and forgot about it.The bike got so hot that it melted all the rubber hoses and plastic parts till it quit running.Kinda suprised it did not catch fire.Anyway,the bike was trailered to the shop to have all the fried parts replaced.The bike still ran like new.No oil consumption or loss of power.
Lastly,those love jugs look like $hit! But if the bike is just going to sit running,any shop fan will work.
My 2014 Chieftain had 95,000 miles and was never apart when I traded it for my 2017.After doing the BBK on the 2017(50,000) it was a moody bike not suitable for me so I got a great deal on my Springfield 111/stg2.Keepin her 4 sure.
