HURRAY!!! I fixed it, I noticed he had put it on upside down and the heat sink logo (Corsair)was vertical instead of horizontal, also the radiator was on upside down. I took off the heat sink, and there was just one tiny corner that the thermal paste had covered. I have now repositioned everything the way it should be and my temps right now running prime @4.4GHz are 64c Maxlooking on the Corsair website and seeing the way everything was on there got me wondering.
Edit: just a image to show it's working fine now this is at 4.60GHz

Is there a certain way the H80i has to be put on then? Any chance you have a picture of which way you put it, as I don't understand which way it should be.
With my base unit tower standing up, looking at the Corsair logo is vertical. Is that right?
