thanks for all of the suggestions,

I looked at the review on hardware secrets to see how well this cooler performed against other coolers, it seemed to perform middle of the road, not the best or the worst
what I did notice is that is does run hotter in my system than when tested in the review, but I do have a very small cramped office without much air or ventilation
I will turn hyper threading off and see if that makes a difference
could anyone possible suggest a good cooler to use with my system?
