This DC5V 2.5W 0.5A cooling fan carries part number 6-31-L140S-102 L14CU and is built for the EGC-75040S1-0AH chassis. It suits owners who need a direct swap for a worn or noisy original unit. Buyers who want a universal cooler or a different voltage should look elsewhere.

Questions about this item

Will the 6-31-L140S-102 L14CU fan need bearing lubrication or a full swap after long use?

The fan is a sealed DC5V 2.5W 0.5A unit; bearings are not user-serviceable, so plan a full replacement when airflow drops or noise rises.

What limit appears first when the cooler runs continuously at 2.5W?

Sustained 2.5W draw at 5V makes the 0.5A current the first ceiling; the motor hits its thermal design limit before any voltage headroom is used.

How loud and hot does the L14CU get during all-day operation?

At 5V 0.5A the fan spins at its rated speed; expect a moderate airflow hum and warm exhaust air, but no extreme noise or surface heat.
