How To Check If Your Laptop Fan Is Working Or Not
The laptop fan is the main cooling mechanism for your internal electronics. The fan extracts heat from the motherboard and processor before exhaling it out the fan vents. This resembles a radiator that exhales hot engine exhaust from a car.
If the laptop frequently becomes hot or the fan makes a slight audible sound but you can’t hear air blowing out of the vents, it’s possible that the fan is malfunctioning. You should correct it if you can. Right?
In order to extend the system’s lifespan and usefulness, a fan is essential. Numerous issues, such as sluggish performance and unstable software, might be brought on by a hot laptop. Application crashes and frequent shutdowns can harm the laptop’s hardware.
Internal components may suffer major malfunctions and damage as a result of overheating. Examining the laptop fan is simple. Make careful to replace the fan to avoid any potential issues.
The main purpose of a fan is to keep the system cool. The laptop fan is in charge of maintaining the laptop’s internal temperature. The laptop will function at its peak in this manner. The performance of the system can be slowed down by this electronic device’s rapid heating. As a result, all programmes will freeze or run slowly. Other components of your laptop may get hurt if your fan breaks.
Certain laptop components may become overheated as a result of the broken fan. If you don’t address the heating issue, your machine could sustain damage as a whole.
In the end, a laptop fan can be crucial and needs to function effectively. How can you tell whether a fan is malfunctioning? is the genuine query.
Check the Fan
Listen to Noise
The best way to see if your laptop is working properly is to listen to the fan that is spinning. The fan will make a faint audible sound, which you can listen to. The majority of laptops produce a typical noise while operating.
Put your ears behind the keyboard, close to the bottom of the laptop. Modern laptop fans occasionally malfunction. When you are engaging in processor-intensive activities like video editing, gaming, or image processing, the fan will turn on. When carrying out operations that put a strain on the processor, the system may quickly become warm.
If your laptop doesn’t make any noises when it switches on, you shouldn’t be alarmed. This occurs as a result of the computer’s slowest speed.
Manufacturers frequently put the fans under strain to boost battery performance and efficiency.
Playing a high-resolution game or streaming a 4K video will make your laptop fan turn on. Your fan may generate jagged pulsing and shrieking noises while listening in on you.
Feel for the Air
The sound of the fan need not be audible to you. One can feel the air coming from the laptop’s vents. Your laptop’s exhaust might be found on the bottom, right, or left. You’ll have to find it. A sheet of paper can then be positioned in front of the fan output. The fan may be operating if the paper even slightly blows. Or, you can use your bare hands to feel the heat coming from the vents.
Given their size and elegant design, modern computers might not completely blow out a sheet of paper. These are the simplest techniques for examining a laptop’s fan. There are other ways to see if the fan is working as well.
Watch out for errors
Your laptop may have a problem if it repeatedly restarts without notice, runs slowly, or displays a Blue Screen of Death (BSOD). The heatsink cooling system could be malfunctioning even though your fan is functioning properly.
Testing using an application
It is possible to use software to check the laptop fan’s functionality. Numerous internet tools offer data on things like temperature and fan speed.
Testing for Windows
The most popular Windows application is SpeedFan. It can keep track of the temperature of various sources and modify the speed of the fans either manually or automatically depending on the temperature of the system.
The CPU temperature can also measur by SpeedFan. temperatures of the hard drive and the casing. For a more in-depth view, turn to the chart tab.
Testing on Mac
On a Mac, you can also use the IStat Menu. You may access fan statistics as well as other other functions, including Hard Drive, Battery Sensor, Palm Rest Temperature, and numerous more choices.
The Fanny widget is available for macOS. It has been in use by me for a time. Both the fan speed and the current CPU temperature are shown. It begins at boot time and is easy to use and effective.
Testing with Ubuntu Linux
On computers running the Ubuntu Linux operating system, Im-sensors or fan control packages must install in order to measure fan speed and temperature.
- Sudo aptget install Im-sensors
Now, run the app by using the command
- Sudo sensors-detect
For speed fans:
- Sensors | grep fan
The command will output fan speed.
These are some of the basic methods I used to test your laptop’s fan. I also included the software solution to test the fan.
It will help you determine the impact of a fan on laptop performance and longevity. It would help if you also keep your laptop in top running condition. This will ensure that your laptop is reliable and efficient.
