Genuine Dell Vostro 5390 5391 CPU Heatsink Assembly
This genuine Dell OEM replacement heatsink assembly (part number DGKGM/460.0GW02.0011) is built for the Vostro 5390 and 5391 laptop series. It combines copper heat pipes, an aluminium fin stack, and an integrated cooling fan in one unit. The part directly replaces the factory-installed cooler to restore thermal performance. It is intended for technicians or owners repairing overheating or fan-noise issues on these specific models.
Passive Heat-Pipe Limits
The cooling method relies on passive heat pipes paired with an active fan to move heat away from the processor. Thermal paste is required for installation but is not included with the assembly. Without fresh compound, the contact between the CPU die and the copper base will be insufficient, leading to continued throttling or shutdowns. The design is fixed to the original thermal envelope of the Vostro 5390 and 5391 chassis and cannot be upgraded beyond that capacity.
OEM Screw Mount Build and Daily Repair Implications
The assembly uses an OEM screw-mount design with aluminium and copper construction for durability. Mounting points align precisely with the existing motherboard standoffs, so no modification is needed during replacement. The integrated fan connector matches the board header, ensuring immediate operation after fitting. This unit does not support other laptop series or desktop sockets, so buyers needing a cooler for a different platform must source the correct part number.
