Delta 5 V notebook fan

The Delta KDB05105HB-BJ23 is a 5 V DC case fan rated at 0.40 A for notebook and small-form-factor cooling. It suits repair technicians and builders who need a direct replacement for the original blower in compatible laptops or compact chassis.

Upgrade from a failed or noisy OEM blower

Replace the factory fan when bearings wear out or airflow drops below specification. The swap is worth it when the original part number matches KDB05105HB-BJ23 and the system runs on a 5 V header.

Questions about this item

Will the KDB05105HB-BJ23 fit my notebook's 5105 mounting pattern?

The KDB05105HB-BJ23 is built to the 5105 form factor used in compatible notebooks. Verify your service manual lists this exact model before ordering.

How do I install the KDB05105HB-BJ23 and what step is often missed?

Remove the old fan, disconnect its cable, fit the KDB05105HB-BJ23 into the 5105 bay, reconnect the 5 V 0.40 A header, then reassemble. The missed step is forgetting to peel the protective film off the thermal pad.
