HTC Vive Focus CPU Fan Replacement

はじめに

Power down your device before you begin. Be careful not to power on your device while making repairs. If you accidentally power on your device, stop working and power it back off before you resume.

This repair requires breaking the plastic welds that help secure the front cover to the device. If you complete this repair, the gaps between the plastic front cover and side panels will no longer be flush. This damage is permanent but only cosmetic and will not affect the device’s functionality, usability, or operation.
