Laptop fans are the primary means of keeping your Laptop’s internal hardware at a constant temperature. The fan removes heat from the motherboard and processor and expels warm air from the exhaust winds; this is the same principle as a heat pump that blasts heat from a car engine.
It’s not uncommon for laptops to overheat when the fan isn’t audible, so it’s crucial to ensure it is working correctly. And there’s a way you can fix it. Right?
A laptop’s fan is critical to increasing the life and usefulness of the computer’s components. The Laptop’s hardware can be damaged by an overheated laptop, causing repeated shutdowns, device crashes, and perhaps damaging the laptop hardware.
The internal components of a computer system might be severely damaged or fail if it becomes too hot. How to Test Laptop Fan is Working or Not is simple and should be done frequently. To avoid future issues, get the buggy fan replaced.
The Importance of a Laptop Fan
It’s self-evident what a fan does on a computer or laptop. Naturally, it utilizes to cool the device. Almost any fan is capable of performing this function. However, why is it necessary to cool your laptop?
One of the primary reasons for this is maintaining your laptop operating at peak performance. A device rapidly heats up and claims that the temperature will not work satisfactorily. As a result, all programmes may experience performance degradation and possibly crash while executing.
A more severe issue is that a damaged fan can also cause damage to other components of your laptop. Certain features are incapable of withstanding a certain amount of heat. If the heating problem resolves, the entire notebook may fail.

To summarise, the fan is a critical component of any laptop and must function correctly. However, how do you determine whether something is amiss? That is the subject we will continue to discuss:
How to Test Laptop Fan is Working or Not?
Since the laptop fan is concealed within the cover, you will not see it operating unless and until the case is open. You can check the fan’s operation in a few simple ways.
- By paying close attention to the sound of the laptop fan running in quiet
- By sensing the air exiting the laptop’s vents
- By utilising software that displays your system’s hardware specifications
#1) Through the Sound of a Laptop Fan
The laptop fan is constantly spinning to dissipate heat generated by the laptop; it slows down when the load increases and accelerates when the computer is under extreme stress, such as when running intensive software or games.
Thus, the way I will demonstrate is relatively simple; you approach your ear closer to the laptop fan, which is often positioned on the sides and bottom of the laptop body, and you will hear a whirring sound.
However, if you do not hear this sound, do not be alarmed; modern laptops are engineers to turn on their fans only when the load increases and turn them off automatically while the computer is in rest mode to conserve energy and resources.
Therefore, you must turn on your laptop and launch some programme or open Chrome and play a high-definition video. You should now be an expert to hear the sound of the laptop’s fan.
Note: Normally, the fan sound is smooth; if you hear a jagged and rough sound, the fan is either broken or has a flaw, or it is dirty; in this case, you must open the case, clean and replace the fan, or get assistance from a mechanic.
#2) By Sensitizing the Air Exiting the Laptop’s Fan Vent
Because laptops are generally built to be portable and easy to carry and use, their fan is small, and the air that comes out of them is also barely noticeable. Therefore, you must place some cloth and paper next to the laptop vents. If there is a tiny movement, the fan usually operates and exhausts the laptop’s air.
Put your hands in front of the laptop fan exhaust locations to experience the warm air as well. This process for determining whether or not your laptop fan is functioning correctly is straightforward and effective.

#3) By Using Software to Display the Hardware Specifications of Your System
Numerous pieces of software are available for monitoring the statistics and performance of your hardware devices. By utilising this Software, you will gain detailed information on your hardware’s performance, heat output, and operation. Many of this Software also detect and report hardware faults and errors.
You can control some of your hardware devices with this software. For instance, you may regulate the speed of your fan, among other things. I recommend that you download and use software such as Burnin test and Core temp, both free to use.
This software pushes your laptop computer to its limits, measuring the speed and heat generated by the processor. And these results will provide detailed information about how your laptop or computer is performing, allowing you to determine if there is a problem with your laptop fan, so do check it out.
#4) Software for Checking Laptop Fan in Windows
Accurate Temp, Speed Fan, Arhus Monitor, and HW Monitor are just a few examples of applications that Windows users can use to monitor their computer’s performance and not just version. These programs will enable you to exert complete control over your hardware.
Among these programmes, “Speed Fan” and “Real temp.” are particularly popular and frequently used. You’ll be an expert to adjust the speed of your laptop’s fan and monitoring your system’s temperature.
You’ll also learn what temperature is detrimental to your system, and when that temperature reaches, you’ll need to instantly turn off your laptop and wait for it to cool down.
Before Taking Your Laptop to a Repair Shop, What Can You Do to Prevent Overheating?
If your laptop is overheating, try the following measures first before contacting technical support:
#1) Vents Need to Be Cleaned
- Shut down your Laptop.
- Unplug the machine and disconnect your devices.
- Gently remove the battery.
- Blow out any accumulated dust with pressurized air that can hold at a 90-degree angle away from the vents.
- Activate the laptop by reinstalling the battery and pressing the power button. Check to see if the problem with the computer overheating has been rectified.
#2) Switch to Balanced Power Mode on Your Laptop
- Do a right-click on your laptop’s battery icon.
- You can select the Power Options.
- In the following window, select the Balanced option. As a result, the CPU and GPU will not be utilized to their full potential.
#3) Update Your Drivers!
- Open the app by searching for Device Manager in the search box.
- Update the drivers for the fans that they are controlling.
- As an alternative, you can search the driver database of your device’s maker’s website for appropriate files.
#4) Use the power management app provided by the manufacturer
- Find out if there’s any power management app for your brand by searching the name on Google.
- Start with Windows Store if that’s an option for you. Download Dell Power Manager, for example, if you have a Dell laptop. Thermal management is included in that app, and you may choose between Optimized, Cool, and Quiet under the Thermal Settings menu.
