Questions about this item

How do I install the KDB05105HB fan in my ASUS Zenbook Prime UX21A, and what step is often missed?

Disconnect the battery, remove the bottom case, unplug the old fan cable from the motherboard header, swap the fan, then reconnect the cable before reassembling; the step most people skip is unplugging the battery first.

What maintenance will the DC05V 0.4A fan need later?

Clean dust from the blades and vents every few months with compressed air; if bearing noise appears or airflow drops, replace the fan with another KDB05105HB unit.
