The ideal you're shooting for is "just cold enough to not cause any dangerous knocking" + "hot enough to keep itself clean so it doesn't foul quickly and misfire". It's a delicate balance, and going colder when you don't need to can be detrimental in the long run if those colder plugs build up carbon fouling.
