I came accross this article claiming if you change the thermal paste the chips run 20 degrees cooler. So did Intel really go cheap on the thermal paste?
PC Watch purchased a high quality paste and used it instead of what Intel ships the Ivy Bridge chips with. The result was an 18-23% drop in temperature, which also means thereís potential to clock the chip higher without having to make the switch to a more expensive cooling solution.
As the thermal paste is used underneath the heat spreader the chips ship with, itís a little bit more involved to replace it when compared to the paste used between the chip and a heatsink. However, if you intend to overclock then itís going to be worth the effort.
Looks like they took the metal casing off of the top of the processor to do the overclocking.
