Ivy Bridge runs hotter than Sandy Bridge, and you are pumping in a LOT of voltage, what clock speed are you running at? 1.4v is pretty high, closed loop coolers such are never as good as their custom loop counterparts, often even beaten by a good air cooler.
Drop your voltage down lower than 1.4v.
An intel 3820 is sandy bridge. And yes I know it will never be as good as a custom loop but it shouldn't be that bad. 1.4v is also not that high for sb-e
