Introdução

The fan in a Lenovo Yoga C740-14IML provides the laptop with air to cool its system.

A fan may go bad naturally by wear on the device over time. This may be accelerated due to lots of dust and debris being sucked in, causing more strain on the fan motor. A faulty or stuck fan may need to be replaced.

Lenovo C740-14IML laptops have a single fan assembly with one fan in the assembly, whereas C740-15IML laptops also have a single fan assembly, but have two fans. In this guide a C740-14IML model is used.

Common symptoms of a bad fan are:

Excessive Heat
Frequent and Unexpected Shutdowns
Slow Performance
Unusual Noises Like Whirring or Grinding

All of these symptoms are good indicators of a bad fan, but you will need to disassemble the device to be sure.

Before you begin, power off your laptop and disconnect the charger.
