Sources say Alder / Raptor Lake fans are compatible with Intel's 15th generation Arrow Lake CPU

CTOnews.com, Oct. 25, according to an installation manual shared by source Albert Thomas, Intel's 15th generation Arrow Lake CPU, although it uses LGA1851 sockets, is compatible with fans with existing Alder Lake and Raptor Lake processors.

Thomas said that there are already a number of all-in-one machines planned to be equipped with Intel's 15th generation Arrow Lake CPU, and according to the exposed installation manual, the Arrow Lake CPU is compatible with all the all-in-one fans released since the release of the Alder Lake in the fourth quarter of 2021.

CTOnews.com previously reported that Intel LGA 1851 slots are generally close to the existing LGA 1700, but the details have changed.

The biggest change is the increase in the number of bumps contacting pads from 1700 to 1851, an increase of 151pins and a year-on-year increase of 9%.

However, the size of the slot itself has not changed, it is still 37.5mm x 45mm.

In addition, the Z height (the distance from the top of the motherboard to the CPU cover) remains almost the same, but there are some slight height differences that can theoretically be made up by washers.
