Doesn't look like they did anything to compensate for the loss of mounting pressure. Heat density and the cores only being directly under three of the heat pipes may well be part of the issue as well.
Still, I'd like to see a lapped cooler or block tested, with the same mounting pressure as would be applied if the IHS were intact (meaning stick a 2.5mm thick washer, or similar, under the retention arm).

Should of used a water cooler tbh....
That chip wasn't anywhere near the thermal limit of an NH-D14.
Total heat production is less than Sandy.

All such talk was utterly baseless.
People are idiotic and backwards. Someone says 5.5GHz, everyone believes it. Then actual chips are tested, getting only 4.6-4.8 on air, and no one believes it.
End result: lots of disappointed fools when the actual CPUs show up.
