Supermicro SNK-P0067PSMB

The Supermicro SNK-P0067PSMB is a 1U passive CPU heatsink engineered for Intel Xeon Scalable processors on the X11 Purley platform. While similar in structure to the SNK-P0067PSM, this model is specifically validated for WIO and SuperBlade server architectures and features a proprietary middle-air-channel design optimized for those chassis airflow patterns.

Technical Specifications

• Socket Compatibility: FCLGA3647-0 (Socket P) – Narrow ILM only

• Platform: X11 Purley (1st & 2nd Gen Intel Xeon Scalable)

• Maximum TDP: Up to 165W

• Form Factor: 1U proprietary height

• Cooling Type: Passive (relies entirely on chassis airflow)

• Dimensions: 108mm (L) x 78mm (W) x 25.5mm (H)

• Special Design: Integrated middle-air-channel aligned with specific air shrouds

---

System & Platform Compatibility

The SNK-P0067PSMB is validated for:

• X11 Generation 1U WIO (Wide I/O) servers

• 8U SuperBlade series systems

Platform support includes:

• Uni-Processor (UP)

• Dual-Processor (DP)

• Multi-Processor (MP) configurations

Because it is passive, proper high-pressure chassis airflow is mandatory for thermal stability.

Comparison of X11 1U Passive Heatsink Models

To avoid confusion, here are the differences among the three primary 1U Narrow ILM X11 heatsinks:

• Supermicro SNK-P0067PS

  • Standard 1U passive design

  • No middle-air-channel

  • Supports up to 205W TDP

  • Best for traditional 1U rackmount chassis

• Supermicro SNK-P0067PSM

  • Proprietary middle-air-channel

  • Supports up to 165W TDP

  • Validated for TwinPro and BigTwin multi-node systems

• Supermicro SNK-P0067PSMB

  • Proprietary middle-air-channel

  • Supports up to 165W TDP

  • Validated for WIO and SuperBlade architectures

---

Important Technical Constraints

• TDP Limit: 165W maximum

• Mounting Requirement: LGA3647-0 Narrow ILM only

• Not compatible with Square ILM socket variants

Summary

The SNK-P0067PSMB is a specialized 1U passive heatsink tailored for X11 WIO and SuperBlade server platforms. Its proprietary middle-air-channel ensures proper alignment with blade and high-density airflow designs, making it unsuitable for standard rackmount systems unless airflow compatibility is verified.

If needed, you can confirm your Xeon processor’s TDP rating to ensure it does not exceed the 165W cooling limit of this heatsink.
