Sts90 hello there mate.
I think if you are coming from 2600K which was a very cool CPU to the 2700X you are certainly going to notice significant temp differences.
Also the voltages that these AMD is in the ball park too. You can manually set the voltage to 1.4 and see how that works out for you. The CPU will boost up to 4.3GHz out of the box and there are a whole heap of cores to power mate.
Your cooler will do the job as you have clearly seen it do. Would a upgrade in cooler make a difference, yes if the upgrade was significant. Say to a 320 AIO or a custom loop. Worth doing? I do not think so unless you really plan in OC the CPU more.
