If you're very concern about temp, you can remove the heat spreader and replace the typical crap thermal paste with something better.
You could do that but it's a huge hassle and it voids your warrenty. I guess my point is that while thermsal paste isn't as good as fluxless solder it isn't horrible. It's not bad enough to be worth the time, hassle and voided warrenty.
