Replacement CPU Cooling Fan

This new original Sunon MF40050V1-Q040-G99 fan operates at 5 V and draws 1.25 W of power. It is designed as a direct replacement for a failed or noisy laptop CPU cooler. The unit suits repair technicians and owners servicing compatible notebook models.

Questions about this item

How long can the 40 mm Sunon MF40050V1-Q040-G99 fan run at 1.25 W before its bearing limit shows up?

The sleeve-bearing design is rated for continuous operation at 5 V and 1.25 W; lifespan is limited by bearing wear under sustained load.

What noise and heat level does the 5 V 1.25 W Sunon cooler produce when running all day?

At 5 V the fan spins at its rated speed, generating a low-profile airflow noise and minimal case-temperature rise inside a laptop chassis.
