Questions about this item

How do I confirm the BATA0710R5H fan spins correctly after installing it in my ThinkPad E440?

Power on the laptop, enter the BIOS hardware monitor and verify the CPU fan RPM is reported and rises under load; listen for steady airflow from the vent without rattling.

Does the package include the 04Y1366 heatsink assembly or thermal paste for the E531, or must I buy them separately?

The listing supplies only the BATA0710R5H cooling fan; the heatsink and thermal compound are not included and must be sourced separately.
