Seems a touch high, at least on idle, I have a noctua down draft cooler and it idles at about 30-32, on load I am much higher than yours though. You could check to make sure it is fastened properly or try changing your thermal paste, but really, your load temps seem reasonable.
Oops, sorry, I got his post and your post confused, didn't realize you were the OP, thought you were responding to me lol. I think your temps are pretty good, considering, you may want to try re-applying thermal paste. The dh-14 and the hyper 212 are pretty similarly styled coolers so I wouldn't expect the 212 to best it that much at idle, regardless of price.
