In this guide I will help you to remove and replace the cooling fan in a Dell Latitude D600 laptop. The cooling fan in this model is buried deep inside the laptop under the top cover. Also you can use this guide for cleaning the cooling module and removing dust from the heat sink and fan.

If your laptops shuts down on its own without any warning, most likely it happens because of overheating. Make sure the cooling fan works and the heat sink is not clogged with dust. Replace the fan if it failed or clean the heat sink if it’s clogged.

Before you start, turn off the laptop, unplug the AC adapter and remove the battery.

When you are replacing the cooling fan, it is not necessary to remove memory, hard drive, wireless card or optical drive. I did that only because I was upgrading the laptop.
