Hi newcomer and welcome to the Tom's hardware forum
What is your specific question? Yourself said, the temperature is great for your processor, the case is more that enough. Now, if you want know that is the normal temperature of the 965 at stock, well, is dificult, 'cause not all the people have the same specifications for the 965.
I have a 955 at stock with the stock heatsinks, my case is a Thermaltake V9 and the CPU's temperature is 44C, BUT my processor is 125W.
