Replacement fan for Microsoft Surface tablets

This replacement fan carries part number ND55C22-18L31 and is built to fit compatible Microsoft Surface tablet models. It operates at DC5V with a 0.50A current draw. Each unit is tested before shipping to confirm basic operation.

Upgrades a worn or noisy original cooler

The part replaces the factory cooling fan when the original unit becomes loud, fails to spin or stops moving air. The jump is worth it when the tablet throttles under load or shuts down from overheating. Matching the exact part number is required for 100% compatibility.

Steady airflow during extended workloads

Under sustained load the fan maintains continuous rotation at its rated voltage and current. The 0.50A draw keeps power demand modest while the impeller pushes air across the heatsink. Performance stays consistent as long as the tablet's thermal system remains clean.

Questions about this item

Will the Delta ND55C22-18L31 fan align with the screw holes and connector on my Microsoft Surface tablet?

The fan is built to the ND55C22-18L31 specification, so its mounting points and cable match the original Surface cooler; compare the photos to your existing fan before fitting.

What is the installation step most people miss when swapping this DC5V 0.50A cooling fan?

After securing the fan, reconnect the delicate ribbon cable fully — partial seating causes the tablet to overheat or report a fan error.

How often should I expect to replace this Surface CPU cooler fan under normal use?

Each unit is tested before shipping; typical lifespan matches the original Delta fan, so plan a replacement only if noise increases or speeds drop.
