Intel Arrow Lake CPUs For LGA 1851 Socket Will Reportedly Bring A Hotspot Shift Towards North
The existing LGA 1700 coolers may have a problem with different orientations as LGA 1851 "Arrow Lake" CPUs will have a different hotspot location.
A 180-degree block hotspot shift may affect the thermal performance of Intel Arrow Lake "LGA 1851" CPUs
The upcoming Intel Arrow Lake CPUs will use the newer LGA 1851 socket and while the socket size is roughly the same as the LGA 1700, there are some small yet crucial differences between the two. The differences are not only present on the socket but the dies for the CPUs themselves.

The Intel Arrow Lake "LGA 1851" CPUs will be almost identical in size to the 12th/13th/14th gen processors but they will have a different cutout configuration so that users won't be able to install them on the LGA 1700 socket. Now with Intel shifting to a different process node and architecture for the Arrow Lake processors, it's obvious that the die design will differ from the Raptor Lake Refresh family.
This is exactly what the popular overclocker Der8auer (via @Unikoshardware) has talked about recently on the Overclock forum. As per Der8auer, the Intel LGA 1851 "Arrow Lake" CPUs will bring a shift in the hotspot. For every generation of processors, the hotspot has been slightly different and sometimes this shift occurred from CPU to CPU in the same family.
A hotspot is the location on the IHS(Integrated Heat Spreader) where the processor heats the most and is generally the area where the cores are located inside the chip. The hotspot exists on both AMD and Intel processors and has different locations on the die, which is why CPU cooler manufacturers release dedicated blocks for each CPU family.
Compared to the LGA 1700 processors, the hotspot on Intel LGA 1851 CPUs such as Arrow Lake series will be shifted a bit towards the north. The LGA 1700 processors had the hotspot somewhere around the center. This helped in cooling the
