Introduction
If your Dell XPS 13 7390 is constantly overheating or frequently shutting down, it may be caused by a failing fan system.
Over time, the fans can stop working due to an overworked motor or burned wiring. If you notice that your laptop is running hotter or if it starts to become noisier, it may be time to replace the internal fan unit.
Before you begin this repair, power off the laptop completely and disconnect any external devices.
