I recently built a 9950x3d system and it definitely runs hotter/louder than my other builds. To be fair, it also has a 5090 in it, but I liquid cool the 9950 and over all the system is just hot. If I saw 165W rated on a 170W system, I think that kind of just answers it, I see no reason not to overcool a system with high end electronics on it, and there's no reason to toe the line so closely.
