About the 412-AATQ
The Dell 412-AATQ is a Dell PowerEdge R750 High Performance CPU Heatsink (>205W 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-AATQ transfers heat efficiently into chassis airflow streams.
Compatibility
Compatible with processor sockets on Dell PowerEdge R750, R750XA systems, the 412-AATQ matches chassis airflow shroud dimensions and processor TDP ratings. The 412-AATQ 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 03V42N, mechanical alignment pin guides, and CPU socket designation. Cooling fin assemblies on the 412-AATQ 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-AATQ, inspect the aluminum cooling fins for bending, crushing, or particulate blockage that restricts airflow. Check the copper contact base of the 412-AATQ for deep scratches or gouges that could impede thermal conductivity, and verify that all spring-loaded retention screws turn smoothly.
