Dedicated LGA1156 Xeon heatsink

The Supermicro SNK-P0046P is a purpose-built CPU heatsink for Intel Xeon X3400 and L3400 series processors in LGA1156 sockets. It is engineered specifically for 1U rack-mount servers where vertical clearance is restricted. This accessory targets system integrators maintaining or assembling compatible Supermicro platforms.

Verify Supermicro platform compatibility

This heatsink only fits Supermicro motherboards, barebones and chassis; it will not mount on third-party boards even if they share the LGA1156 socket. Confirm your server model appears on the vendor compatibility list before ordering. The mounting pattern is proprietary to Supermicro designs.

Low-profile black aluminium construction

The unit measures 95 mm by 95 mm with a height of 27 mm (1.06 in by 3.74 in), allowing it to sit within a 1U enclosure. A black anodised finish resists corrosion in dense rack environments. Passive operation relies on directed chassis airflow rather than an integrated fan.

Questions about this item

Does the SNK-P0046P heatsink include mounting hardware or thermal paste?

The package contains the heatsink only. Mounting hardware and thermal compound are not included and must be sourced separately for installation.

Which Xeon series is the SNK-P0046P designed for?

This heatsink is built for Intel Xeon X3400 and L3400 series processors in an LGA1156 socket.

Will the 27 mm height fit inside a standard 1U server chassis?

At 27 mm tall the cooler matches the 1U form factor, but it is validated only for Supermicro motherboards, barebones and chassis.
