Replacement Fan for Asus U31 and X35 Series

This replacement CPU fan fits Asus U31, U31F, U31J, U31E, U31JG, U31JF, U31S, U31SD, U31K, X35J and X35 models. It is intended for owners of those laptops who need to replace a noisy or failed cooler. The part is supplied new and tested before shipping. Buyers with different laptop series cannot use this fan.

Tested Unit Ships Ready to Install

Each fan is tested individually to confirm 100 % operation before it leaves the supplier. The component draws power from the standard laptop header and runs at the original thermal design limits. No extra wiring or software configuration is required. The package contains only the fan; thermal paste or mounting hardware are not included.

Direct Swap for KDB0705HB Assembly

The fan matches the KDB0705HB form factor used in the listed Asus chassis, so it fits the existing screw points and connector. It frees the builder from sourcing a complete cooling assembly when only the fan has failed. Builders needing a different connector layout or a dual-fan module must look elsewhere.

Questions about this item

How do I install the KDB0705HB fan in an Asus U31 series laptop and what step is often missed?

Remove the bottom case, disconnect the old fan cable, unscrew the heatsink assembly, swap the fan, reapply thermal paste on the CPU and GPU, then reassemble in reverse order. The step most people miss is cleaning the old paste completely before applying new compound.

What maintenance will the KDB0705HB fan need after several months of use?

Blow compressed air through the heatsink fins every few months to clear dust buildup. Listen for bearing noise or vibration; if the fan develops a rattle or slows down, replace it rather than lubricating the sealed bearing.

What is the first limit the KDB0705HB fan hits during sustained heavy loads?

The thermal limit of the laptop chassis appears first. The single fan can only move so much air through the heatsink, so CPU temperatures will climb until the system throttles clock speeds to protect itself.
