Let me start by saying, as has already been said, your temps are ok under load. Personally, with the cooler you posted, I would have looked for lower load temps. I would expect your load temps to lower as the AC5 sets in over the next week or so, and if they don't, I might be tempted to pull the cooler and check 1) the CPU for flatness (my 940 needed lapping to cool properly under my TRUE), 2) the coverage of the heatsink compound, and 3) to check what temp the TEC portion of that HS is supposed to "kick in". I am jealous of your heatsink as I have looked at it with greed in my eye, just couldn't justify spending the cash on it.
