About the 412-AALM
The Dell 412-AALM is a Dell PowerEdge R740 Standard 2U CPU Heatsink (<150W TDP) designed to dissipate thermal energy from high-performance processors in Dell PowerEdge servers. Engineered with copper heat pipes or vapor chambers and stacked aluminum cooling fins, the 412-AALM transfers heat efficiently into chassis airflow streams.
Compatibility
Compatible with processor sockets on Dell PowerEdge R740, R740XD systems, the 412-AALM matches chassis airflow shroud dimensions and processor TDP ratings. The 412-AALM mounts securely to motherboard retention brackets using spring-loaded Torx screws to ensure balanced contact pressure across the CPU IHS.
How to identify a genuine unit
Authentic Dell heatsinks feature an etched or labeled DP/N 02G30W, mechanical alignment pin guides, and CPU socket designation. Cooling fin assemblies on the 412-AALM are finished with uniform anti-corrosion plating, and factory thermal interface material pads or protective plastic covers protect the polished copper contact base during shipping.
Buying used
When purchasing a used 412-AALM, inspect the aluminum cooling fins for bending, crushing, or particulate blockage that restricts airflow. Check the copper contact base of the 412-AALM for deep scratches or gouges that could impede thermal conductivity, and verify that all spring-loaded retention screws turn smoothly.

FAQ
Can this standard heatsink be used with 205W Xeon Gold/Platinum CPUs?
No, processors exceeding 150W TDP require the High Performance heatsink (412-AALN) with integrated heat pipes.
What tool is needed to torque down this heatsink?
A Torx T30 screwdriver torqued to 12 in-lbs is required to secure the heatsink to Socket P0.
