Compatible GPU Fan for Asus Eee Pad 121

This replacement GPU cooling fan is built for the Asus Eee Pad EP121 and B121 tablets. It matches the KDB05105HB-AH1F and KDB05105HB-AH1G part numbers. The unit runs on 5V power with a 0.40A current draw. Each fan is tested before dispatch to confirm it spins correctly.

Suitable for owners of the listed Asus tablets

This part suits anyone repairing a noisy or failed GPU fan in an EP121 or B121 device. It is not for users with other Asus models or different laptop series. The connector and mounting must match the original exactly. Buyers who cannot verify the part number against their old fan should not order this item.

Electrical rating of 5V and 0.40A

The fan operates at 5 volts and draws 0.40 amps. This specific rating determines whether the component will work with the tablet's power delivery. Confirm that the original fan carries the same voltage and current values before fitting. A mismatch in either figure will prevent correct operation.

Questions about this item

How do I install the 5V .40A GPU fan in my Asus Eee Pad EP121 B121, and what step is often missed?

Disconnect the battery, remove the old KDB05105HB-AH1F or AH1G fan, connect the new 3-wire plug securely, then reassemble; the step often missed is reconnecting the battery before testing.

What maintenance will this Forcecon, ADDA, Sunon or Kipo replacement fan need later?

Clean dust from the heatsink fins and fan blades every few months with compressed air; the sleeve bearing is not user-lubricatable, so plan to replace the unit if noise or vibration returns.

What limit appears first when the 5V .40A fan runs continuously under load?

The 0.40 A current draw caps cooling capacity; sustained heavy GPU loads can push thermals past what this single 80 mm-class blower can dissipate, leading to throttling.
