Why Do Laptop Fans Get Loud?

There are a few reasons why laptop fans can get loud. One reason is that the fan is trying to cool down the laptop’s processor, which is working hard and generating a lot of heat. Another reason is that the fan might be dusty and need to be cleaned. Finally, the fan speed might be set to high, which can make it noisy.

However, the most common cause of laptop fan noise is the build-up of dust inside the laptop and blocking the ventilation. If you look at the bottom of your laptop, you’ll see a vent hole. This is where air enters the computer chassis. As it passes through the vents, dust particles get sucked into the system. Over time, this can build up and causes the fan to run constantly loud.
