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

Laptop fans are the primary cooling mechanism for your computer system’s internal hardware. The fan removes the heat from the motherboard, the processor and expels the warm air from the exhaust winds & this is the same mechanism as a heat pump that blows heat from a car engine.

The fan creates a modest audible sound, but if your fan is inaudible, you can’t sense that the air is flowing from the air, and most importantly, the laptop gets hot sometimes. And there’s something you ought to do about it. Right? 

The fan plays a vital role in extending the life and usability of a laptops systems. A superheated laptop does not work to the mark and can cause many problems such as frequent abrupt shut-downs, device crashes, and probably harm the laptop’s hardware.

Overheating may result in a severe failure or damage to the system’s internal components. It’s easy to check your laptops fan and should be done regularly. Make sure that the buggy fan is replaced to save you from future problems.

Significance of Fan

The evident duty of a fan is to refresh the system, if any system. In our case, the laptop fan does the same to hold the laptop within the air, for the very reason of keeping the laptop at its best. 

As an electronic, physical device like this, the machine can quickly heat up and thwart its efficiency. As a result, all programs are slowed or crashed.

The biggest concern with a broken fan is that it can affect other parts of the laptop. Since specific components in the laptop cannot support the heat level induced by the malfunctioning fan. If you do not fix the heating problem, the entire system is in danger of being broken down.

Therefore, the heart of the debate is that a laptop fan is of immense importance and must function well. Now the real question, how to check if laptops fan is working? It is what we will now investigate.

How to Check if Laptop Fan Is Working

Laptop fans eject air and make audible sound soft to moderate under regular use. If your laptop fan is quiet, the air close to the ventilation is cool, and the laptop is very hot, the fan is probably not working. 

Laptop coolers play an essential role in laptop durability and reliability, and if it works at all, an overheated device will not work well. Make sure you quickly fix a faulty fan to avoid hardware failure.

#1 Noise Listen

A properly working laptop fan can sound like a soft propeller fan, but when you first turn the machine on it, the fan may not be audible since it operates at its most slow speed. The fan accelerates as you begin to use your laptop. 

After around five minutes, your laptop is likely to turn to a quicker, louder mode when it is operational. The best-cooled laptops can have too casual fans that attentive listeners only hear in quiet spaces. Note that your fan can be broken or obstructed by intermittent noises of pulsation or loud screaming.

#2 Air sensation

Even if you can’t hear the fan function, you should feel the air coming from the air. The airflow can be very light while the device has been switched on. 

Still, it is taken off when the machine reaches the average operating temperature. The laptop fan may begin to remove the air from the primary exhaust air typically located on one side of the laptop.

Place your side, face the system, about half an inch from the ventilation, and feel the airflow. If the laptop is quiet and no airflow is present, maybe the fan is broken. 

If you can hear the fan work hard but experience only mild airflow from the winds, it can block the fan, in which case the winds are clear by a compressed air explosion.

#3 Watch for errors

If your machine periodically restarts without warning, usually stops, or gives you BSoD or Blue Death Screen, the fan may be a concern. The fan is connected to a heatsink as part of the cooling unit, so even if the fan blows air, another part can cause problems. If the cooler is loose or the thermal compound that bridges the CPU and the cooler wears out, your device can overheat.

#4 Check the Temperature

Even if the fan expels some air out of the ventilation, there might still be a hardware issue, such as an engine problem, that prevents your machine from cooling correctly. 

Some laptops show a temperature read when you trigger them, but when you do not, use a hardware monitor software to check the CPU temperature (see Resources). If your laptop doesn’t do something, the fan can be broken if it reports a constant temperature above 160 degrees Fahrenheit.

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

How to Check if Laptop Fan Is Working

Laptop fans are an essential part of cooling your computer’s internal operations. They suck heat out of the motherboard and processor and blow off hot air, just like a fan of the radiator blows hot air away from the motor car. 

Overheating your computer can cause significant component dysfunctions and damage, which can require expensive repairs. Checking the fan of your laptop is critical and simple enough to do it regularly.

Step 1: Switch your computer on. Turn your computer on. It would help if you told me where a cooling fan is located and where it blows the hot air, depending on the laptop type. 

Place your ear in the body of your laptop to that point and listen to the fan. You should be able to hear it if it’s going. You should use other ways to test your fan if you cannot listen to it.

Step 2: Place a piece of paper before the production of the fan. You can not hear the fan, but you can see if a piece of writing is being blown, even if it is only a little bit. It also decides whether or not the fan works.

Step 3: Download and run a BurninTest, SpeedTest, or Core Temp software. All these programs are free online; push your computer processor to its limits, and measure the processor’s speed and heat.

It checks the stress your machine can withstand and diagnoses heat errors. With these findings, you will find out how efficiently your laptop fan works and if it works correctly.

How to Check if Laptop Fan Is Working Through Software

The final step is to download free SpeedFan applications.

It is a free application that can be downloaded from its original website or other multi-software pages. What does this app mean?

It has been developed to allow PC and laptop users to test their computer for potential problems safely. It looks mostly like this if it is installed and ready:

The first screen displays the readings received from the laptop when you open the app. The type of GPU and CPU your laptop uses can be identified.

It is a positive thing because many GPUs are made up of devoted fans. This program will measure the fan that your particular GPU uses. It can also be customized for unique needs.

The key and most significant aspect of the software is that it allows you to track the temperature of almost any considerable component in your laptop.

As before, you can see the actual temperature on your hard disk, GPU, and CPU on the main tab.

If you have a multi-core (quite likely) CPU, the temperature will be shown for each core in use.

If you look at each element’s temperature and it seems too high, you probably have a problem with the fan.

But it would help if you also searched for another performance from SpeedFan.

It will directly test the laptop’s main fan. More specifically, it will tell you how well your fan works. In this way, you will know if your fan is incorrect.

Fortunately, this is also available for any other fan you may have built, such as the GPU fan.

When the laptop is used heavily, and you also feel that it accumulates heat, the fan does not work as it was planned.

If the issue continues, first try cleaning up your laptop fan, and then it’s easier to replace your fan with a new one.

If the fan works well, but your laptop still overheats, this approach is perfect for gaming laptops.

SpeedFan is one of the best and most powerful programs for detecting laptop/PC problems. You can use it at any time since it is free to use. Keep this in mind: even though your laptop seems to be working well right now, something could happen in the future.

It is why SpeedFan is best installed for any situation. The fan is a crucial element on any laptop, but you can also detect issues with several other components using SpeedFan.
