Intel Xeon LGA4677 cold plate
Package carrier and power reviewSpecify a CPU cold-plate assembly for an LGA4677 server or workstation. Review the package carrier and approved power profile before choosing retention and flow requirements.
Fit and compatibility
- Fourth- and fifth-generation Xeon Scalable processors use LGA4677. The Xeon w9-3495X is also an LGA4677 example and requires its own workstation board and chassis fit check.
- Intel documents E1A, E1B and E1C package carriers for the two Xeon Scalable generations. Verify the carrier for the actual CPU and use the corresponding loading and retention hardware.
- Check port direction and installation tool access around the DIMMs and voltage regulators. Confirm the plate and hose clearance with the approved fan shroud installed.
Scope of supply
- Define the cold plate, retention hardware and thermal interface for each populated socket. Request the assembly drawing and mounting procedure for the exact carrier and board.
- For two CPUs, define the hose branches, connector pairs and manifold interfaces. Identify whether existing flow sensing and leak monitoring can cover the added branches.
Operating conditions
- Intel lists the fifth-generation Xeon Platinum 8592+ at 350 W TDP with an E1A carrier. Use the actual CPU power settings and the plate performance curves for the proposed fluid and temperature.
- When the two CPU branches run in parallel, check each branch against its minimum flow at the pump operating point. Include the pressure losses across the tubing, fittings and plate.
Acceptance checks
- Inspect carrier seating, retention and thermal interface installation before closing the chassis. Confirm both branches maintain the specified flow after filling and bleeding.
- Run the agreed sustained CPU workload and record temperatures and throttle flags for each socket. Verify memory and voltage regulator temperatures with the final airflow configuration.
