Laptop Fan Failure

The laptop fan is an integral part of any laptop. Laptops create an enormous amount of heat and excessive heat can cause components to fail. Combine that with the fact that laptops are getting smaller and more compact, and there is even less room for air to circulate. All of these factors make the laptop fan or fans an even more important component. Since the laptop fan is such an important part of a laptop, it is wise to know the signs of a failing laptop fan.

1. Overheating

Almost every laptop will heat up somewhat under heavy use. In most cases, you will hear the fan begin to spin faster and make more noise when this occurs. If your laptop begins to get excessively hot and the fan does not appear to be spinning faster, it may be failing.

2. Strange noises

If you hear strange whining or grinding noises, the source could be a failing laptop fan. In some case, the bearings of a fan wear out or lose their lubrication, and the result is a noisy or grinding fan. You should replace it immediately.

3. Laptop locking up

If your laptop freezes or locks up, especially when performing a processor-intensive task, it could mean a laptop fan failure. Excessive heat is one of the primary causes for computer freezes. If this problem persists, try replacing the laptop fan.

4. Fan keeps running

In some cases, the laptop fan may continue to run and run at full speed, even when the laptop is not hot enough to warrant it. This can also be a sign of a failing fan, as it is not responding to the laptop’s signal to lower the fan speed.

Replacing a laptop fan can be a simple job or a very complex one depending on your laptop model. Some fans are easy to access, while some require a lengthy disassembly process. You can check around in search engines for replacement instructions specific to your model to take some of the mystery out of replacing your laptop fan.
