Created At 8 months ago

The fan in a Lenovo laptop is indispensable for reducing overheating and prolonging the life of internal components. Removing and replacing the fan requires technical know-how and the right equipment. A Lenovo laptop's fan can be replaced with this tutorial.


It's crucial to get everything together; you'll need to replace a fan before you do anything else. In addition to a clean, static-free work area, you may require screwdrivers, a replacement fan, thermal paste (if applicable), and so on.

First, ensure the laptop is turned off and disconnected from any power sources. Take the precaution of removing the battery before doing any repairs, just in case.

As the location of the fan and the method of removing it can vary depending on the type of Lenovo laptop, it is also recommended to consult the user manual or a professional repair guide for detailed instructions.

Accessing the Fan

Finding the fan on the laptop is the first step in replacing it. The fan is typically hidden behind a panel or screws next to the heat sink.

You can get at the blower in the following ways:

  • Look for the screws or covers that fasten the fan into place.

  • Carefully pry off any screws or panels blocking your path to the fan with a screwdriver.

  • If you're replacing a fan, now is the time to double-check the wiring, so you know exactly how to reinstall it.

A word of caution: screws and panels may be small and easy to lose. Hold on to them in order and security until the maintenance is done.

Removing the Old Fan

What you need to do to get rid of the old fan is:

  • You need to unplug the fan and remove any cords or connectors holding it together.

  • Carefully remove the fan from its mount, keeping in mind its orientation and any other attached parts.

  • Set the new fan aside and remove the old one.

When the thermal paste was used to adhere the old fan to the heat sink, it was recommended that the surface be cleaned before the new fan was installed. For this purpose, you can use either regular rubbing alcohol or a dedicated thermal paste cleaner.

Installing the New Fan

Here are the steps you need to take to set up your new fan:

  • Connect the new fan using the same cables and connectors as the old fan.

  • The fan must be installed in the correct hole at the correct angle.

  • Don't overtighten the screws holding the fan in place, or you could damage the motor.

Note: To enhance heat transfer, apply a small layer of thermal paste to the heat sink surface before mounting the fan. Applying thermal paste in excess can have a detrimental effect on performance, so be sure to read and follow the manufacturer's guidelines.

Final Steps

You should run a few additional checks after installing the new fan to ensure everything is in working order with your laptop.

  • To ensure that your laptop is effectively cooling, turn it on and ensure that the fan is spinning.

  • Laptop screws and panels should be replaced before reassembly.

  • If the battery needs to be replaced, do so now, and reconnect any connecting cords and devices.

  • Make that the laptop is operating normally and that there are no other problems by testing it.

Note: If you have any issues while testing, please consult the user manual for your Lenovo laptop or contact a qualified IT support service. Keeping your Lenovo laptop up to date with regular maintenance and repairs will help keep it running smoothly for longer and improve its overall performance.
