Laptop fan for HP ProBook 640 G4

This replacement cooling fan fits HP ProBook 640 G4, 645 G4 and 640 G5 models. It mounts directly inside the chassis to draw heat away from the processor. The part carries reference numbers L09535-001 and L09537-001 for easy identification. It is supplied new and ready to install.

Integration into a repair build

The fan connects to the existing motherboard header without extra adapters. It frees the system from thermal throttling caused by a worn or noisy original cooler. No additional cables or brackets are required beyond what the laptop already provides. Buyers needing a different form factor or a dual-fan assembly should look elsewhere.
