Thermals, Noise and Power Draw

The dual-fan unit handles heat from both the CPU and GPU during normal workloads. No decibel ratings, airflow figures or power-consumption data are supplied by the manufacturer. Installers should verify fitment using the part numbers before fitting the fans.

Questions about this item

How do I install the CPU+GPU cooling fan in my ThinkBook 13s-IWL and what step is often missed?

Remove the bottom cover, disconnect the battery, swap the old fan assembly for the new DFS5K123043630 unit, reconnect the cable, then reinstall the cover. People often forget to unplug the battery first.

What maintenance will the replacement fan need later?

Clean dust from the heatsink fins and fan blades every 6–12 months using compressed air; the sleeve-bearing motor is not user-lubricatable, so replace the whole unit if noise or speed drops.

What limit appears first during sustained loads on this fan?

The single 5 V PWM fan reaches its maximum RPM before the heatsink saturates, so prolonged heavy workloads hit the fan’s airflow ceiling first.
