Supermicro CPU cooler 1U for socket 4677 passive SNK-P1046V

High-density 1U servers demand reliable cooling that fits within tight vertical clearance. The Supermicro SNK-P1046V passive heatsink solves this by providing efficient thermal dissipation for Intel Xeon Scalable processors in LGA4677 sockets without adding fan noise or power draw. Its copper base and aluminum fins transfer heat effectively, relying on system airflow to keep your CPU within safe operating temperatures.

Who is it for

This cooler is ideal for system integrators, data center operators, and IT professionals building or maintaining 1U rackmount servers based on 4th Gen Intel Xeon Scalable (Sapphire Rapids) platforms. It suits environments where space is at a premium and low acoustic noise is required, such as colocation facilities, edge computing nodes, and high-performance computing clusters.

Tips

Ensure your chassis provides adequate front-to-back airflow; this passive cooler relies on system fans to move hot air away from the heatsink. For optimal performance, pair it with high-static-pressure fans in the chassis. Always verify that your motherboard's CPU socket orientation matches the heatsink's mounting holes before installation.
