Supermicro - CPU-kylfläns SNK-P0070APS4

The Supermicro SNK-C0009A is a passive CPU heatsink engineered specifically for 1U rackmount servers, where space is at a premium and reliable thermal management is non-negotiable. Unlike universal coolers that compromise on fit, this heatsink is built for Intel Xeon Scalable processors using the LGA 3647-0 socket with Square ILM, ensuring a precise, secure mount in Supermicro 1U chassis. Its all-aluminum construction and fin design maximize heat dissipation through forced chassis airflow, eliminating the need for a dedicated fan and reducing points of failure. For system builders and IT administrators seeking a dependable, low-maintenance cooling solution for high-density compute environments, the SNK-C0009A delivers the exact compatibility and performance required.

Highlights

• Passive cooling design: no moving parts, silent operation, and lower power draw.
• Optimized for 1U rackmount servers: low-profile height fits tight vertical spaces.
• Supports Intel Xeon Scalable processors up to 165W TDP (processor dependent).
• Square ILM (Independent Loading Mechanism) mounting for LGA 3647-0 sockets.
• Durable aluminum construction with efficient fin geometry for maximum heat transfer.
• Designed for Supermicro 1U chassis with directed system airflow.

In daily use

In a densely packed server rack, every component must work in harmony. The SNK-C0009A relies on the chassis's existing fans to pull air across its fins, carrying heat away from the CPU. This passive approach means one less fan to monitor, replace, or fail—crucial for mission-critical deployments. Installation is straightforward with the required Square ILM mounting kit (sold separately), and because no thermal interface material is pre-applied, you can choose the TIM that best suits your environment. The heatsink's low profile ensures compatibility with standard 1U enclosures without obstructing other components.
