Anyone who has been keeping up with the reviews coming out which try overclocking Intel’s new Ivy Bridge processor will be familiar with the large amount of power required to hit high frequencies.  While the voltages required to overclock Ivy Bridge and its predecessor Sandy Bridge are very similar, Ivy Bridge’s stock voltage is lower so the change is greater for Ivy Bridge.  That larger increase could be one cause of the higher heat that Ivy Bridge generates.  Another theory is that the heatspreader could be a cause as Intel used thermal paste in the design as opposed to the fluxless solder present on SandyB, however other tests have shown that this does not seem to be the case.  The Tech Report has gathered together the current facts on this hot topic, so you can check out the numbers for yourself right here.

"Folks across the web have reported some eye-poppingly high temperatures for their overclocked Ivy Bridge processors, leading to some tough questions about the causes. Does Ivy Bridge truly run hotter than its predecessor, Sandy Bridge, and if so, why? We checked into it, and the answers were surprising, to say the least. Have a look."
