## Long description

Dell heatsink with fan assembly for OptiPlex/Precision (ASSY HTSNK UMA W/FAN 5280) is a direct-replacement cooling module designed for compatible Dell desktop systems. The assembly integrates a metal heatsink and an axial fan to remove heat from CPU and nearby components. It includes factory-aligned mounting points and a power connector for straightforward installation into supported OptiPlex and Precision chassis, restoring active cooling performance and helping maintain stable operating temperatures under load.
Advantages
The integrated design combines a contoured heatsink and a matched fan to improve heat transfer and airflow compared with passive solutions. As a direct-fit assembly it preserves original mounting alignment and connector type, minimizing installation time and the need for modification. The active fan offers consistent airflow to reduce thermal throttling and supports sustained performance during compute-intensive tasks. The assembly is intended to replace worn or failed cooling components to help extend the usable life of the system.
Suitable for
Repairing or replacing a failing CPU/GPU cooling assembly in compatible Dell OptiPlex and Precision desktops
Restoring thermal performance after fan failure or heatsink damage
Maintaining system stability under regular office workloads and light to moderate multimedia or compute tasks
Key specifications
Type: integrated heatsink with axial fan (active cooling)
Compatibility: designed for specified Dell OptiPlex and Precision desktop platforms (verify model fitment before purchase)
Cooling target: CPU and adjacent heat-generating components
Mounting: factory-aligned mounting points for direct replacement installation
Connector: standard board-mounted power connector for fan supply
Material: metal heatsink with thermal interface contact surface
How to use
Power down the computer, disconnect it from mains, and open the chassis following the manufacturer service guidelines. Remove the existing heatsink and fan assembly according to model-specific instructions, clean the processor surface of old thermal compound, and apply a suitable new thermal interface material. Position the replacement Dell heatsink assembly so mounting points align with the board, secure fasteners to the recommended torque and reconnect the fan power connector. Reassemble the chassis and run a controlled boot and temperature monitoring to confirm correct operation.
Usage recommendations
Verify model compatibility against system documentation before installation. Use manufacturer-recommended thermal compound and tightening sequence to ensure proper contact. After installation, monitor temperatures under typical workloads and ensure unobstructed airflow in the chassis; replace the assembly if abnormal noise, vibration, or elevated temperatures persist.
