Questions about this item

Does the DBTLAP cooling fan package include mounting screws or thermal paste, or just the fan itself?

The package includes one fan only; mounting hardware and thermal compound are not supplied and must be sourced separately.

How do I confirm the DELTA KDB0505HA-BL3Y 5V BA31-00131A is the correct replacement for my laptop?

Compare the part number on your original fan with BA31-00131A and check the photos to ensure the connector and mounting holes match before ordering.

What does the 5V rating mean for everyday cooling performance once the fan is installed?

The fan draws 5 volts from the laptop header, delivering the airflow the original DELTA design specifies for that model.
