Replacement heatsink for Latitude 5280

This Thinkstar CPU assembly fan heatsink is built for the Dell Latitude 5280. It matches part number 3XN3N and arrives in a black finish. The unit is new and has been tested by the supplier. It suits technicians or owners repairing that specific laptop model.

Tested unit ready for installation

The part ships as a complete assembly so no separate fan or bracket sourcing is required. Supplier testing confirms the fan spins and the heatsink mates correctly. Buyers needing a different laptop series or a bare heatsink without the fan should look elsewhere. No thermal compound or mounting hardware beyond what is shown is included.

Questions about this item

How often should the fan in this 3XN3N heatsink assembly be cleaned or replaced?

Clean the fan and heatsink fins whenever dust buildup becomes visible, typically every six to twelve months in normal office use; replace the whole assembly only if the fan becomes noisy, fails to spin or cooling performance drops noticeably.

What is the first thermal limit reached when the Latitude 5280 runs a sustained heavy workload with this cooler?

The CPU will hit its factory thermal throttle point first; the heatsink and fan are sized for the stock 5280 power envelope, so prolonged maximum load causes the processor to reduce clocks before the cooler itself saturates.
