Socket LGA 3647 Server Cooler

The Dynatron B12 is a passive heatsink designed for Intel Xeon processors using the LGA 3647 socket. It targets system integrators building 2U rack servers or taller chassis where a low-profile thermal solution is required. The unit ships with Shin-Etsu 7762 thermal compound already applied to the copper base.

64 mm Height Constraint

This cooler measures 64 mm tall and fits the vertical space of a 2U server enclosure. The aluminium fin stack sits on a copper base with embedded heatpipes, transferring heat upward for a chassis fan to exhaust. Builders using 1U cases or custom enclosures with less clearance cannot use this model.

Square ILM Mounting

Installation relies on the square Independent Loading Mechanism native to the LGA 3647 platform. The package includes only the heatsink; no fan or mounting hardware for other socket types is provided. Buyers needing active cooling or compatibility with different server sockets must select a different product.

Perguntas sobre este artigo

Which fan should I pair with the B12 for my 2U server build?

The B12 uses vertical fan mounting on a 90 mm square base; choose a PWM fan rated for server airflow that fits the 64 mm height limit.

Will the 64 mm height fit in a standard 2U rack chassis?

Yes, the 64 mm height is designed for 2U server and up, leaving clearance for the chassis lid and airflow.

Does the LGA 3647 socket support Xeon Platinum and Gold processors?

The B12 is built for the Intel LGA 3647 socket used by Xeon Platinum and Gold families with Square ILM.
