If I take gaming in general, on the P12, I was running rpms close to max, around 1.7+K, with the P12 Max and the 5C drop, rpms were around 2.5k. I don't have a db meter so can't really quantify the noise level.May I know at what rpm of the fan speed and noise level in dba to dropped 5c ?
Maybe some reviews like this one might give you some clues to the difference in noise:
