We reported a couple of days ago that Intel’s latest Ivy Bridge might be hot due to crappy thermal paste used between IHS and the die itself. A PC EVA did some testing to see if that’s really the issue but unfortunately that’s not the issue.
He stripped down an Intel Core i7-3770K quad core processor and mounted it with Noctua NH-D14 cooler and Prolimatech PK-1 thermal paste. He overclocked the processor to 4.5 GHz with 1.2v but temperatures were almost identical to the ones that were recorded with the IHS. This means that thermal paste used by Intel isn’t causing heating.
