TBH It looks good. Though personally what I would do is see if the chip is capable of doing a lot higher say like 4.8Ghz. If you're able to pass an hour of Prime95 at that speed then I would start thinking of investing in a heavier duty cooler so you can run those clocks consistently.
On the other hand if your chip doesn't want to go much higher than what you are on, then I would say stick to the clocks you're getting. As for the temps you are getting I would say they are pretty good and pretty much in line with the performance potential of the Hyper 212 Evo.
