Compatible ASUS models

This replacement CPU fan fits ASUS K550D, X750DP, K550DP and K550 laptops using the KSB0705HA part number. It is intended for owners of those specific notebooks who need a direct swap for a worn or noisy original cooler. Buyers with different ASUS series or other brands cannot use this unit.

Thermals and noise

Each fan is tested individually before dispatch to confirm 100 percent operational status. The component draws power from the laptop's own header and runs at the speed the system firmware requests, so acoustic output and thermal response match the original design. No external power or control software is involved.

Sustained-load behaviour

Under continuous load the fan maintains the airflow profile defined by the laptop's embedded controller, keeping the processor within its normal temperature envelope. The 9-month warranty period covers defects in materials or workmanship. Builders needing a second fan for a dual-fan chassis or a higher-CFM upgrade should look elsewhere.

Questions about this item

How do I install the KSB0705HA fan in my ASUS K550D, and what step do people get wrong?

Remove the old fan, disconnect its cable, fit the new unit to the heatsink, reconnect the 4-pin plug, and reassemble; the step most people miss is cleaning old thermal paste off the CPU and GPU dies before refitting the heatsink.

What maintenance or replacement will this KSB0705HA fan need later?

The fan uses a sleeve bearing; expect rising noise or wobble after extended use, at which point the whole fan must be swapped out.

What limit shows up first on the KSB0705HA under sustained load?

The sleeve bearing’s heat tolerance is the first bottleneck; prolonged high RPM leads to lubricant breakdown and bearing wear before airflow drops off.
