Before using this guide, check faulty fan(s) for foreign objects that cause underperformance. You may be able to fix his issue by dislodging said objects with an ESD-safe brush or small dust blower, instead of replacing the equipment. Be sure to isolate fan(s) that are nonfunctional as a replacement of only one fan may be needed.

Before beginning, be sure to power down the laptop, and unplug from the external power source(s).
