Replacement CPU Fan for ASUS N45 N55 Series

This replacement CPU fan fits ASUS N45 and N55 laptop models including N45SL, N45SF, N55S, N55SF, N55SL and N55X. It matches part numbers KSB075HB, BB24, 13GN5F1AM020-1 and 13GN6L10T010-1. The unit is supplied new and tested individually before dispatch. Buyers who need a complete cooling assembly with heatsink should verify compatibility before ordering.

Thermal Performance and Power

The fan restores original airflow to the processor heatsink, reducing core temperatures under load. Each unit is tested to confirm 100% operation before shipping. Noise level and power draw match the original specification for the supported models. Laptops with dual-fan designs may require both fans replaced for balanced cooling.

Build Quality and Installation

The package includes one fan sourced from manufacturers such as Forcecon, ADDA, Sunon or Kipo depending on stock. Connector layout and mounting holes follow the original design for direct fitment. Photos show the actual item; compare with the existing fan before purchase. A nine-month warranty covers defects in materials and workmanship.

Questions about this item

How do I install the KSB075HB fan in my ASUS N55 and which step is most often done wrong?

Remove the bottom cover, disconnect the old fan cable, unscrew the heatsink assembly, swap the fan, then reconnect the cable before refitting the heatsink; the step most often missed is re-seating the heatsink screws in the correct diagonal order.

What maintenance will the BB24 fan need after months of use?

Blow dust from the blades and intake vents every few months with compressed air; the sleeve bearing is not user-serviceable, so plan to replace the whole unit when noise or vibration appears.

At what point does the 13GN5F1AM020-1 fan hit its thermal limit during sustained loads?

The fan runs at a fixed 100 % duty cycle, so the first limit reached is the heatsink’s ability to dissipate heat; once the CPU temperature stops dropping despite maximum airflow, the cooling pad can no longer improve thermals.
