In 100-105º temps in sport mode and pushing it a bit this is about where i sit. I wouldn't worry about it at all. Most people i know with dodge products, their cooling fans do not even come on until mid 220s. Makes you think something is wrong, but i assure you it's fine. The cars are smarter than us when it comes to what they can handle.. and if it were to overheat, it goes into a fail-safe mode to protect itself.
