Skylake also greatly improves its temperature with delid

Since the arrival of Ivy Bridge, Intel processors have used to have overheating problems, especially in overclocked conditions, which have prevented them from exceeding the overclock levels achieved by Sandy Bridges that do not suffer from this problem.

As is already known, this is due to the fact that from Ivy bridge Intel stopped soldering the IHS to the die of the processor, damaging the heat transfer to the heatsink with the consequent problems of overheating, something that was aggravated with Haswell by the inclusion of a voltage regulator inside the processor itself and that has been partially solved with Skylake by removing this regulator from the processor and putting it back on the motherboard.

However Skylake continues to suffer from overheating with overclocking as demonstrated by the guys at PC Watch with a Core i7 6700K. In their tests they have removed the IHS to the Core i7 6700k and have found a very small die result of the manufacturing process at 14nm, even smaller than that of the i7-5775C.

The most interesting thing is that after replacing the thermal paste put by Intel with a Cool Laboratory Liquid Pro, the temperature has been reduced by 20ºC in overclock conditions to 4.6 GHz and a voltage of 1, 325v. In stock conditions, the temperature has also been reduced, but to a lesser extent, 16ºC. The same test was carried out with the Prolimatech PK-3 thermal paste, showing a much smaller improvement in temperatures, 4ºC both in stock and in overclock.
