Questions about this item

Does the package include mounting screws or a heatsink, or must those be sourced separately?

The fan ships alone; screws and heatsink are not included and must be obtained separately.

My laptop is an HP CQ43 — which part number confirms this fan is the correct match?

Part number 646184-001 is listed for the CQ43, so this fan matches that model.
