Heatsink Compatibility: Current LGA1700 Coolers to Work with Future Intel LGA1851 CPUs

The compatibility between processor sockets and coolers is a critical consideration for PC enthusiasts and manufacturers alike. Recent announcements from Azza have confirmed that the current LGA1700 socket heatsinks will be fully compatible with Intel‘s upcoming Arrow Lake processors, which are set to use the new LGA1851 socket.

Manufacturers often provide anchor kits to ensure hassle-free transitions between sockets, enabling users to make the most of their existing cooling solutions.

A Glimpse at the LGA1851 Socket and Arrow Lake Processors

The anticipated release of Intel’s Arrow Lake processors in late 2024 will introduce the LGA1851 socket, featuring an increased pin count of 1,851 contacts, representing a 9% augmentation from its predecessor. Notably, the LGA1851 retains the same dimensions and mounting space as the LGA1700, maintaining a consistent form factor that remains unchanged for several years.

One notable upgrade in the LGA1851 socket is the significant increase in maximum dynamic pressure, boasting an 89% surge compared to the LGA1700. This heightened pressure highlights the need for improved heat dissipation capabilities within the compatible heatsinks.

Intel’s Strategy and Processor Improvements

Noctua, a renowned manufacturer of cooling solutions, has indicated the compatibility of its existing retail coolers with the LGA1851 socket, without mentioning the need for additional mounting kits. In light of this, the leaked Azza Cube 360 manual on Reddit has not indicated any supplementary anchoring accessories.

Intel’s Arrow Lake processors, according to an internal leaked slide, promise a 21% performance boost over the Raptor Lake Refresh series, with a TDP of 250 watts. While specific details about energy consumption remain undisclosed, the retention of energy efficiency is anticipated.

Furthermore, the LGA1851 socket, set to debut with the 15th Gen Arrow Lake processors, is expected to remain in use until 2026, marking a departure from Intel’s earlier socket strategies, likely influenced by competition from AMD‘s Ryzen socket.

The Shifting Landscape: Speculations on Future Sockets

Speculations suggest that the upcoming launch of AMD’s Zen 5 processors, expected to feature heterogeneous cores, might necessitate a replacement of the existing AMD AM5 socket. These processors are anticipated to launch around the same time as Intel’s Arrow Lake, potentially marking a parallel shift in socket technologies for both manufacturers.

As the industry prepares for these advancements, the importance of cooling compatibility and thermal management continues to play a central role, ensuring that PC enthusiasts can seamlessly integrate new technologies while leveraging existing hardware solutions.
