Questions about this item

How do I verify the NS85B01-15F02 fan spins correctly after installing it in my ASUS N543UA?

After fitting the cooler, power on the laptop and listen for the fan to start; the BIOS or a monitoring tool should report an RPM reading above zero, confirming the fan is running.

Does the 13NB09W0T02011 cooler come with mounting screws or thermal paste, or must I buy them separately?

The listing shows only the CPU fan assembly itself; screws and thermal compound are not included and will need to be sourced separately if your original hardware cannot be reused.
