Introduction

This guide will instruct you how to remove a broken Lenovo Y50-70 Touch Fan from your laptop. A touch fan regulates the laptop’s temperature to keep it from overheating, and when it malfunctions it can damage the laptop or make it perform poorly. A fan can get worn out due to frequent use, causing it to malfunction. Dust or debris can also damage the fan. This replacement process requires a careful hand to avoid harming any internal wiring when removing the base of the laptop and the fan itself. To replace the fan, follow these steps in reverse.
