On 4.2ghz on my AMD Phenom ii X4 965 I idle 29-33c and full load 55c and thats on really high voltage like 1.548v on my phenom im really pusing it., if I open my room balcony door and let cold air get it my temp will get down to 45c full load xD, (its winter here). I still think you apply the thermal paste in the wrong way, and btw i suggest you to do this.
Step 1): Buy the arcticlean kit looks like this.
Step 2): Clean the CPU very good, make it shine almost as you can see yourself trough it.
Step 3): Buy the Artic MX -4 thermal paste, one of the best paste out there and its better then the artic silver 5 and it has no curing time, the silver 5 has almost 1 month curing time and the temp will drop down later. So MX-4 is better, its also non conductive and wont harp your componets if you accedently dropped somewhere on your motherboard or cpu pins etc.
Step 4): H80i is ****, its not a good watercooler, even my budget 212 hyper evo is better. (With good fans tho).
Step 5:) If you gonna use the H80i, and after you cleaned the cpu good, put a small pea size of paste in the dead center of the cpu not to litle but not to much either, put it a litle more then a pea size., dont touch the paste and install ur h80i and let the paste spread with the weight of the h80i.
With all this you should get a good temps, I dont think anything is wrong with your cpu, u are just doing it wrong, and probably letting air in paste betwee heatisnk and thermal.
