Arrow Lake's new LGA 1851 form factor has shifted the CPU's temperature hot spot to a different position than it was previously. Der8auer reports on the Overclock forums, that the hotspot has shifted north compared to LGA 1700 Alder Lake and Raptor Lake CPUs, requiring new CPU cooler designs for ultra high-performance waterblocks and coolers to extract the maximum amount of heat from Intel's new Arrow Lake chips.
"Regarding 1851 we are working on making a normal block, too. The hotspot on 1851 is quite a bit further north than it was on 1700. This means for ideal cooling a shift of the cooling center is required to fight the hotspot. It also means that rotating the block 180° would harm the performance. For us it would be the easiest to have the in port north and out in the south orientation," Der8auer wrote on the Overclock forums.
