Supermicro SNK-P0067PSM
The Supermicro SNK-P0067PSM is a 1U passive CPU heatsink designed specifically for Intel Xeon Scalable processors on the X11 Purley platform. It is engineered for FCLGA3647 (Socket P) with a Narrow ILM mounting mechanism and features a proprietary Middle-Air-Channel design optimized for high-density multi-node server architectures.
Technical Specifications
-
Socket Compatibility: FCLGA3647-0 (Socket P) – Narrow ILM only
-
Platform: Intel Xeon Scalable (X11 Purley Platform)
-
Maximum TDP: Up to 165W
-
Form Factor: 1U low-profile
-
Dimensions: 108mm (L) x 78mm (W) x 25.5mm (H)
-
Cooling Type: Passive (no fan attached; relies on chassis airflow)
-
Material: Aluminum heatsink fins
System & Motherboard Compatibility
This heatsink is not universal; it is validated for specific Supermicro high-density systems.
Officially Validated Systems
-
Supermicro SYS-2029TP-HTR
-
Supermicro SYS-F619P2-RT
Compatible Motherboards
-
Supermicro X11DPFR-S
-
Supermicro X11DPT-PS
While primarily validated for the TwinPro and BigTwin series, compatibility is technically defined by:
-
X11 generation motherboards
-
LGA3647 Narrow ILM socket
-
Chassis airflow that matches its passive cooling design
It may be installed on other X11 boards using Narrow ILM, provided the chassis airflow is sufficient.
Key Proprietary Feature: Middle-Air-Channel (M)
The “M” in SNK-P0067PSM indicates a 26mm wide Middle-Air-Channel.
-
Designed to align with specialized air shrouds in 2U 4-node multi-node chassis
-
Optimized for Twin architecture airflow paths
-
Improves cooling efficiency in dense configurations
For standard 1U rackmount servers (non-Twin architecture), the
Supermicro SNK-P0067PS
is often preferred, as it uses a traditional fin array without the middle air gap and supports higher airflow flexibility.
Technical Constraints
-
TDP Limit: Rated up to 165W
-
High-wattage Xeon Gold or Platinum CPUs exceeding 165W may require a higher-capacity heatsink such as the SNK-P0067PS (supports up to 205W).
-
-
Mounting Limitation: Fits LGA3647-0 Narrow ILM only
-
Not compatible with Square ILM versions of the same socket
-
Summary
The Supermicro SNK-P0067PSM is a purpose-built 1U passive heatsink optimized for X11 Purley multi-node platforms using Narrow ILM. Its proprietary Middle-Air-Channel design makes it ideal for TwinPro and BigTwin 2U 4-node systems, but less suitable for standard single-node 1U chassis unless airflow conditions are carefully verified.
