I did some research and understood that corei7 is similar to that of core2quad with hyper threading enabled. I also came to know that it will get hotter and you need a cabinet with good airflow like CM 690 or HAF.
I think a cooler like sunbeam Core contact freezer will reduce the temps even if you don't overclock.
