What To Do When Your Laptop's Internal Fans Stop Working -- And You Can't Get Another Internal Fan

The whir of a laptop fan is a common sound, and the lack of that whir can be alarming. Without a working fan, a laptop can quickly overheat. While most laptops have safety features built in, such as shutting off once the processor reaches a certain temperature, the inability to run lots of programs or even use the computer on a very hot day can be frustrating. The obvious fix is to go get the fan replaced (or get both fans replaced, if the laptop has two that have both broken), but what do you do if you can't get new fans? Sometimes the repair requires that you leave your laptop at the repair center for a few days, and not everyone can do that. If you've got a laptop that you can't send in for repair, here are some things you can do to keep the laptop going.

External Fans and Placement

The next best solution to getting the internal fans replaced is to get external fans and place them at strategic points. You can find laptop stands that have cooling fans built in; if you can't get those, for whatever reason, take a small personal tabletop fan and place it at the side of the laptop's keyboard.

Elevate the fan with blocks so that the fan is blowing air across the top of the keyboard, and keep feeling different spots on the keyboard as you use the computer. Move the fan around -- change the angle at which the air hits the keyboard, change the height, and so on -- to try and make the heat in the laptop as evenly distributed as possible. You also want the hotspots to cool down as much as possible.

Air Conditioning

Try to keep the laptop in a cool spot in the house. If you have air conditioning, use that on hot days because the air temperature can affect how easily the laptop overheats. If you can put the laptop in the path of the cool air being blown out of the air conditioner, so much the better.

Program and CPU Monitoring

Close all the programs that you don't need to run. It's easy to leave programs open so that they're running minor processes in the background, but those can add up and stress out the central processing unit, or CPU. That can raise the temperature in the laptop considerably. Close social media programs that you aren't actively using, close word processing when you're done, and so on.

You may want to see if your utilities folder has a program for monitoring the activity on your computer. These programs often note the load on the CPU and the percentage of the CPU that is idle and not being occupied by running programs. Check the program when the computer starts to feel hot and note the idle percentage. That gives you a benchmark for running programs; you know that you have to keep the idle percentage at or above that level to keep the computer from getting too hot.

Eventually you will have to find a more permanent fix simply because the situation can get quite annoying after a while, but these strategies can keep you going for a while. Your computer might shut down more often because of high temperatures, especially in hot weather, but you should be able to get a good amount of use out of the machine. If you want more information about repairing laptop fans and whether you would be able to keep the laptop with you instead of dropping it off for a few days, contact a computer electronics repair shop.
