The SKU:0WNKHC is a Dell alternative part number for a CPU clip used in Dell PowerEdge R660 and R760 servers.
This code is a Manufacturer Part Number (MPN) used by Dell for internal tracking and compatibility identification of specific components.
These are specialized brackets (or clips) used to secure the CPU heatsink (the cooler) to the motherboard socket, ensuring proper thermal contact with the processor. They are designed for the high-performance cooling assemblies used in modern Dell PowerEdge server systems.
They are small but critical pieces of hardware that ensure the heavy heatsink stays correctly seated on the CPU in a mission-critical environment.
Each clip is engineered to interact precisely with the Dell-branded heatsink and the Dell motherboard's CPU socket bracket to apply the exact amount of pressure required. The clip's mounting points, alignment tabs, and latching mechanism are unique to the physical layout and design of the Dell PowerEdge server chassis and its internal components.
Use cases when these WNKHC Clips are needed:-
1.Replacing a Damaged or Missing Clip
If the original clip is damaged, bent, or lost during server maintenance, you must replace it with the correct Dell part (WNKHC) to ensure the cooling assembly can be properly secured.
2. Replacing the CPU or Heatsink
The clip is part of the assembly process for the newest generation of Intel Xeon CPUs (4th/5th Gen) on the LGA 4677 socket, which are used in servers like the Dell PowerEdge R660 and R760. When you remove the Processor and Heatsink Module (PHM), the CPU is often held securely inside the retention clip, and the clip itself is then detached from the heatsink for replacement or maintenance.
3. Server Error Due to Missing Clip
In older Dell systems, a missing heatsink clip could break a detection circuit, causing the BIOS to prevent the system from booting to prevent thermal damage. While the mechanism has evolved, having the correct, intact retention clip is mandatory for the server's sensors to verify the CPU is properly cooled, allowing the system to operate safely.
