so you have a prebuilt computer that you put the new proc in right? if so the manufacturer may have used a proprietery cooling method, this would be bad the reason the hsf is so hot is because it is not to take all of that heat you havent fried your prescot tho since i belive there is thermal throughtaling on the chip however you NEED a better hsf since your current bracket dose not fit a new hsf i recomend you get a new hsf maybe a xp-90 its like 40 bucks and is a very nice hsf however you may have other problems look for a bios update too this may help with any compatiblaty issues
