Yes they are normal, and depending on ambient temps and airflow inside your case. I currently have the same setup with mine clocked at 3.2ghz with the voltages at 1.2 volts with HT enabled and turbo on running a EL WU, with my temps reaching 68'C under heavy load being cooled by a CoolerMaster Hyper N520 hsf.
I have a HAF 922, with the stock 240mm and a 240mm on the side and a scythe ultra kaze blowing in, and 2 slipstreams and an ultra kaze blowing out. Ambient is ~23. My load temps seem very good but more opinion on the idle please!
I'm in the same boat. Been running Prime95 for an hour. The temperatures were the max of any of the 4 cores for both idle and full load. I made sure to have HT on and 8 threads going in Prime95.

Vcore 1.2
QPI/DRAM 1.2
Your voltages seem really good for 3.6ghz. Unfortunately I wasn't able to get stable results lowering the voltage anything below 1.3 for vcore. Oh well it's still tons below maximum voltage recommended so I guess i'm good
