How to Check if Laptop Fan Is Working? Step by Step

Laptop fans are the major method of cooling the internal hardware of your computer system. The fan extracts heat from the motherboard and CPU and expels it through the exhaust winds; this is similar to how a heat pump extracts heat from a car engine.

The fan produces a faint audible sound, but if the fan is not heard, you will be unaware that air is being drawn from the air, and most significantly, the laptop will occasionally become heated. Additionally, there is something you should do about it. Right?

A laptop’s fan is critical for extending the life and usability of the system. A superheated laptop performs poorly and can result in a variety of issues, including frequent abrupt shut-downs, device crashes, and likely damage to the laptop’s hardware.

Overheating can result in a catastrophic failure or damage to the internal components of the system. How to Check if Laptop Fan Is Working or not is simple and should be done on a frequent basis. Ascertain that the buggy fan is replaced to avoid future issues.

The Importance of Fan

A fan’s obvious function is to refresh the system, if there is one. In our instance, the laptop fan accomplishes the similar thing by keeping the laptop within the air, which is critical for maintaining the laptop’s performance.

As an electronic, physical object, the machine can rapidly overheat, reducing its efficiency. As a result, all programmes become sluggish or even crash.

The primary problem with a damaged fan is that it may cause damage to other components of the laptop. Because specific components within the laptop are unable to withstand the quantity of heat generated by the faulty fan. If you do not address the heating issue, the entire system is at risk of failing.

Thus, the crux of the dispute is that a laptop fan is critical and must perform properly. Now the actual challenge is How to Check if Laptop Fan Is Working? . That is the subject of our current investigation.

How to Check if Laptop Fan Is Working

Under normal use, laptop fans discharge air and produce a gentle to moderate amount of audible noise. If the fan on your laptop is silent, the air around the ventilation is chilly, and the laptop is really hot, the fan is most likely not operating.

How to Check if Laptop Fan Is Working

Laptop coolers are critical for laptop longevity and reliability, and an overheated computer will perform poorly if it functions at all. As soon as possible, repair a malfunctioning fan to avoid hardware failure.

1. Listen to the noise

A properly functioning laptop fan can sound like a soft propeller fan, but when the computer is first turned on, the fan may be inaudible due to its modest speed. As you begin to use your laptop, the fan speeds up.

After approximately five minutes, your laptop is likely to switch to a faster, louder mode. Even the best-cooled laptops might have excessively quiet fans that are audible only in calm spaces. Bear in mind that your fan may be damaged or obstructed by sporadic pulsating noises or loud screams.

2. Sensation of air

Even if you are unable to hear the fan, you should be able to feel the air flowing from the air. While the gadget is turned on, the airflow may be quite light.

Nonetheless, it is removed after the machine achieves its normal operating temperature. The laptop fan may begin sucking air from the laptop’s principal exhaust air vent, which is normally positioned on one side.

Place your side against the ventilation system, approximately a half-inch from the vents, and feel the airflow. If the laptop is silent and there is no airflow, the fan may be broken.

If you hear the fan working hard but only receive light airflow from the winds, the fan may become blocked, at which point the winds are cleared by a compressed air explosion.

3. Keep an eye out for errors

If your computer randomly restarts without notice, frequently shuts down, or displays a BSoD or Blue Death Screen, the fan may be a cause for concern. Because the fan is connected to a heatsink as part of the cooling unit, even if it blows air, another component may cause issues. Your device may overheat if the cooler is loose or the thermal compound that connects the CPU and the cooler is worn out.

4. Temperature Check

Even though the fan extracts some air from the ventilation system, a technical issue, such as a faulty engine, may prevent your machine from cooling properly.

Certain laptops will display a temperature reading when triggered, but if they do not, utilise a hardware monitor software to determine the CPU temperature (see Resources). If your laptop remains idle, the fan may become damaged if it indicates a consistent temperature of more than 160 degrees Fahrenheit.

Step by Step Guide About “How to Check if Laptop Fan Is Working”

Laptop fans are critical for cooling the interior components of your computer. They extract heat from the motherboard and processor and expel hot air, just like a radiator fan expel hot air from a car.

Overheating your computer can result in major component failure and damage, necessitating costly repairs. Checking your laptop’s fan is crucial and simple enough to accomplish on a regular basis.

Step 1: Power on your PC. Switch on your PC. It would be helpful if you could tell me where the cooling fan is positioned and where the hot air is blown, depending on the type of laptop.

Place your ear up to that spot in the body of your laptop and listen to the fan. If it is moving, you should be able to hear it. If you are unable to listen to your fan, you should conduct more tests.

Step 2: Place a piece of paper in front of the fan before it is manufactured. While the fan cannot be heard, you can see if a piece of text is being blown, even if only slightly. Additionally, it determines whether or not the fan operates.

Step 3: Download and run a software programme such as BurninTest, SpeedTest, or Core Temp. All of these apps are available for free online; they will test the boundaries of your computer’s processor and will record its speed and temperature.

It determines the maximum amount of stress that your machine can withstand and diagnoses heat-related issues. These data will inform you of the efficiency and proper operation of your laptop fan.

How to Check if Laptop Fan Is Working Through Software

Finally, download the free SpeedFan programmes.

It is a free programme that may be downloaded from the developer’s website or from other software-related websites. What does this application imply?

It was created to enable PC and laptop users to safely test their computers for any faults. When it is installed and ready, it resembles the following:

When you open the app, the first screen displays the readings obtained from the laptop. Your laptop’s GPU and CPU type can be determined.

This is a good thing, as many GPUs have passionate fans. This software will determine the fan speed used by your GPU. Additionally, it can be tailored to meet specific requirements.

The software’s primary feature is that it enables you to monitor the temperature of virtually any critical component in your laptop.

As before, the primary tab displays the current temperature of your hard disc, GPU, and CPU.

If you have a multi-core CPU (which is rather likely), the temperature for each core in use will be displayed.

If the temperature of each part appears to be excessive, you most likely have a fan problem.

However, it would be beneficial if you also searched for another SpeedFan performance.

It will perform a direct test of the laptop’s primary fan. More precisely, it will inform you of the efficiency of your fan. This way, you’ll know whether your fan is malfunctioning.

Fortunately, this also applies to any other fan you may have constructed, such as the GPU fan.

When the laptop is heavily used and you see that it is accumulating heat, the fan does not operate as intended.

If the problem persists, try cleaning your laptop’s fan first; then, it’s easy to replace the fan with a new one.

If the fan is functioning properly but your laptop continues to overheat, this strategy is ideal for gaming laptops.

SpeedFan is one of the most effective and powerful apps available for analysing laptop/PC problems. You can use it at any time because it is completely free. Bear in mind that even though your laptop appears to be operating normally at the moment, anything could go wrong in the future.

That is why SpeedFan is recommended for all situations. While the fan is a critical component of any laptop, SpeedFan may also be used to diagnose problems with various other components.

FAQs – How to Check if Laptop Fan Is Working

How do I check if my laptop fan is working properly?
