Questions about this item

How often should the EG50040S1-C960-S9A fan be cleaned to maintain cooling performance?

Clean the fan and heatsink vents every six to twelve months using compressed air to remove dust that restricts airflow.

What thermal limit causes the UX430 cooling fan to throttle under sustained load?

The CPU reduces clock speeds once its junction temperature reaches the firmware-defined thermal ceiling, typically around 100 °C.
