878922-001 Screw-Down CPU Heatsink for ProLiant ML110 Gen10 and StoreEasy 1560

The 878922-001 is a screw-down processor heatsink for compatible ProLiant ML110 Gen10 servers and StoreEasy 1560 storage systems. Its tall aluminum fin stack, copper heat-pipe design, and mounting base work with the system’s airflow to draw heat away from the processor.

This heatsink is designed for matching LGA 3647 server configurations using supported first- and second-generation Xeon Scalable processors. Compare your original heatsink’s spare number, mounting base, and fin layout before ordering.

Processor, system fan, and thermal paste are not included.

⭐ Recommended Thermal Paste

Fresh thermal paste is recommended whenever a heatsink is removed and reinstalled. Clean the old compound from the processor and heatsink contact surface before applying new paste.

⚙️ Fit Notes

• Match 878922-001 or one of the listed replacement numbers to your original heatsink.
• LGA 3647 socket compatibility alone does not guarantee fit in another server or workstation.
• This is a passive heatsink; the server’s system fans and air baffles must be installed and operating correctly.
• Verify that the processor retention frame and mounting hardware match your system.
• Follow the numbered sequence on the heatsink when loosening and tightening the mounting nuts.
• Power down the server, disconnect its power cords, and allow the heatsink to cool before service.
• Clean the processor and heatsink contact surfaces and apply fresh thermal paste before reassembly.
