## Long description

Dell ASSY,HTSNK,UMA,W/FAN,5420 is an OEM heatsink with an integrated fan engineered for compatible Dell systems. This assembly provides active cooling for the central processor, transferring heat away from the CPU core to maintain stable operating temperatures under typical and sustained workloads. The unit is intended as a direct replacement for compatible factory cooling modules and is used in maintenance, repair, or upgrade scenarios to restore or improve thermal management in supported Dell models.
Advantages
The integrated heatsink and fan design delivers targeted airflow across the processor surface, improving heat dissipation compared with passive solutions. As an OEM part, the assembly matches original mechanical and thermal specifications for compatible systems, ensuring correct fitment and connector compatibility. The preassembled unit simplifies replacement work and reduces installation time while maintaining system cooling performance and reliability.
Suitable for
Replacing faulty or noisy CPU cooling modules in compatible Dell desktops or workstations
Service and repair operations that require restoring factory thermal performance
System maintenance or refurbishment where verified OEM components are required
Upgrades of cooling assemblies within supported Dell models to maintain stable CPU temperatures
Key specifications
Form factor: integrated heatsink with axial fan designed for OEM system installation
Cooling method: active air cooling using heatsink fins and a dedicated fan
Mounting: designed for direct replacement in compatible Dell chassis with matching mounting points
Connector type: system-specific power connector for fan control (matches original Dell motherboard headers)
Material: metal heatsink construction for effective thermal conduction
How to use
Power down the computer and disconnect it from mains power before beginning. Open the system chassis according to the manufacturer service instructions, remove the existing cooling assembly by releasing fasteners and unplugging the fan connector from the motherboard. Position the replacement heatsink over the processor, secure it to the designated mounting points, and reconnect the fan power cable to the motherboard header. Reassemble the chassis and power on the system to confirm fan operation and normal boot. Apply CPU thermal interface material if required by the service procedure.
