LGA 1700 coolers may lose efficiency on LGA 1851 due to thermal zone shift Arrow Lake processors

With the transition to the socket LGA 1851, processors Intel Arrow Lake will face important changes in thermal architecture that may impact the cooling performance of existing coolers for LGA 1700. Despite the fact that the socket dimensions remained almost unchanged, critical changes occurred inside the chips. As reported by the famous overclocker der8auer, the main problem is hot spot shift processor.

Hot spot - this is the area on the processor cover where the main heat is concentrated, and it is shifted towards the northern part of the crystal in processors Arrow Lake. In previous generations, using LGA 1700, this area was closer to the center of the chip. This allowed for different orientations of the water blocks without affecting cooling. However, now rotating the cooler 180° can worsen thermal performance, since the water inlet and outlet ports will be at opposite ends.

Der8auer recommends posting In-Port on the north side of the water block, and Out-Port - on the south side for optimal cooling configuration. Currently, there are no fastening systems that compensate for this offset, so water cooling systems may lose their effectiveness.
