Hey, I never noticed that before....

You will with an unwanted fan blowing on your back.

Just trying to keep cool.

Now that I think more about it, why would Kirk need to tell them what temperature to set their uniforms? Maybe they have limited charge or something so you don't want to set them too high?

To explain to the audience why they didn't spend the money to create cold-weather gear for the actors.

But why that specific temperature? It would have made more sense for Kirk to tell the landing party: "It's effing cold down there, so adjust your suit temperature to whatever you find comfortable."

Wow, I never noticed that at all.

It took me 30+ years of watching Spock’s Brain to notice Kirk’s order to the landing party.

Exactly. The detail of 72° was for universe immersion, like putting specific names on characters, planets, etc. that are only referenced once and never seen. Or maybe Shatner wanted a detailed line to maintain the portrayal of Kirk as knowledgeable, proactive, authoritative, and (perhaps especially) protective of his crew.

Same, but more like half a century for this old dinosaur, since I still haven't technically noticed it until after I forget this was pointed out and then I watch the episode again!
