yeah you need a better cooler / you should not get beyond 60C when running orthos at only 3.6 volt at least I dont with my E8400
70C is way too hot ..... especially at stock voltage
the unlinking of the cpu and memory is a good thing leave it like that
dont worry about the multiplier, you cant set it higher than 9x and I am not a big believer in the lowering of the cpu multiplier and pushing the memory harder
I am not sure how much you are prepared to pay for the ninja >>>> but I think this one is still the king
