Introduction
If the Dell Precision M3800 fans are nonfunctional and the computer is overheating, use this guide to replace the fan(s).
The fans run to prevent the computer from overheating and continue normal function. Faulty fan(s) will fail at cooling down the laptop and can be an obstacle to normal functions.
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).
