HP ProBook 450 G4 Fan Replacement

Introduzione

If your HP ProBook 450 G4 fan is making excessive noise while powered on, this could indicate a problem with the mechanics of your fan. Before using this guide, you want to rule out that the excessive fan noise is not being caused by an overworked CPU. Check your task manager to see what is using the majority of your CPU. Ending those tasks should restore the function of your CPU and could make your fan quieter. If that does not help, follow the instructions in this guide to safely and properly remove your laptop’s fan. Before beginning, make sure to power off your laptop and disconnect it from all power sources.
