Rectangular copper and aluminium passive CPU heatsink with heat pipes, 80.0 x 104.0 x 64.0 mm, screw and spring mounting

Supermicro

Supermicro SNK-P0048PSC 2U Passive CPU Heatsink LGA2011 Xeon E5-2600

SKU CH-2D20-0QSHY MPN SNK-P0048PSC

Passive copper-aluminium heatsink with heat pipes for LGA2011 Xeon E5-2600 CPUs in 2U X9 servers

  • Passive cooling eliminates fan noise for silent server operation
  • Copper base with heat pipes transfers heat efficiently from Xeon E5-2600 CPUs
  • Designed for LGA2011 narrow ILM socket on X9 2U WIO+ DP servers
  • Compact 80.0 x 104.0 x 64.0 mm profile fits tight 2U chassis spaces
  • Spring-loaded screw mounting ensures consistent contact pressure for reliable thermal transfer

Target Application

This passive CPU heatsink is designed for Supermicro X9 2U WIO+ dual-processor servers. It supports Intel Xeon E5-2600 series processors installed in a LGA2011 narrow ILM socket. The unit is intended for rackmount chassis where system airflow provides the necessary cooling.

Thermals and Power

The heatsink uses a copper and aluminum base with heat pipes and aluminum fins to dissipate heat without a dedicated fan. Thermal performance depends entirely on the forced airflow generated by the chassis fans. As a passive component, it adds zero acoustic noise and draws no electrical power itself.

Build and Mounting

The cooler measures 80.0 by 104.0 by 64.0 millimetres, fitting the 2U form factor height constraint. It secures to the motherboard using a screw and spring mounting mechanism that applies even pressure on the narrow ILM. The construction combines a copper-aluminum base with heat pipes and stacked aluminum fins for structural rigidity.

Questions about this item

How do I install the SNK-P0048PSC on a LGA2011 narrow ILM socket, and which step is often missed?

Align the heatsink over the CPU, then secure the four spring-loaded screws in a diagonal sequence. The step often missed is tightening each screw gradually in multiple passes to ensure even pressure across the copper base.

What maintenance will this passive heatsink need over its service life?

Periodically remove dust from the aluminum fins using compressed air. Since there are no moving parts, the copper heat pipes and aluminum base require no replacement unless physical damage occurs.

What thermal limit appears first when a Xeon E5-2600 runs sustained loads in a 2U chassis with this 64.0 mm tall cooler?

The 2U height constraint caps fin surface area, so case airflow becomes the limiting factor. If chassis fans cannot move enough air through the fins, CPU temperatures will throttle before the heatsink itself saturates.
