Questions about this item

How can I confirm the HC437 fan is spinning correctly after installing it in my 630M or 640M laptop?

After fitting the HC437 fan, power on the laptop and listen for smooth, quiet airflow from the vents; the system should maintain stable temperatures under load without overheating warnings.

Does the HC437 cooling fan package include mounting screws or a heatsink, or must they be purchased separately?

The HC437 is supplied as the fan assembly only; original mounting screws and the heatsink module are reused from the laptop, so no extra parts are required if the existing hardware is intact.
