How to Check if Computer Fan is Working Properly

How to Check if Computer Fan is Working Properly

The most important component of a laptop or a computer is the fan inside. Why? Because if the heat produced inside the computer is not removed, then overheating can damage internal components like CPU, GPU, RAM, SSD, and motherboard.

That’s why it requires you to daily look after your laptop or desktop to make sure the fan is working properly. The major role of a fan inside the machine is to adjust speed according to heat production. But, when the fan is running faster, that means the amount of heat production is increasing and in this scenario, the laptop will also make noise.

Why Checking Fan is Important?

Regarding how expensive and powerful the laptop is, if it is being overtaxed due to heavy workload of complex rendering, intense or demanding gaming, or any due to any other type of activity, and that leads to overheating of the laptop.

Laptop overheating is the biggest concern for laptop users because there are chances that when the laptop is overheating, it will be slowed down or shut down in extreme scenarios. The laptop fan malfunction is the biggest reason most of the times which leads to the 

  • Abnormal shutdown or the laptop
  • Frequent unusual glitches and crashes
  • Unusual applications failure

Not only that, the major drawback when the fans are out of order is the hardware damage because they can only withstand a slight overheating and after that, there will be a greater chance for the components to die away.

Safety Tips of Laptop

Therefore, always invest in a quality cooling mechanism which can be a top-quality cooling fan in Mose cases but there are other alternatives of cooling are available as well.

A powerful cooling fan can alone extra all the warmth out of the machine and will blow it away through exhaust vents result in a cooler internal temperature. That’s when components will be cooler and chilling and that increases the life span of the whole machine.

That’s why it is super important to keep an eye on the fan of the laptop. Now, how to check if the laptop fan is working or not?

There are a handful of ways and we will discuss all of them one by one.

How to check if the laptop fan is working or not?

Before you start any technical analysis, the simple way to figure out if the fan is working or not is the visual inspection, and to be honest, this is the fastest approach to find out if fans have stopped working. If you’re using a desktop computer, the rotating fan can be seen easily on the rear of the PC. In the case of laptops, locate the air vents and there will be the fan.

Visual detection allows you to figure out if the fan is stopped or running. Sometimes fans are not visible so you can hear the fan as well. For newer computers, fans work quietly but when the system is running at full potential and producing a lot of heat then the fans start making noise and start running at high speed. Sometimes fan noise can be unusually loud or abnormal noise which is an indication of fan replacement. 

1- Listening to Fan’s Sound

When you are using the laptop at the maximum potential then fans are rotating constantly as well. Fans start rotating more when the system is running more and slow down when the system is being used normally. So, you can expect some whirling sound.

The finest technique is to put your ear close to the air vents and notice the noise closely. 

Fan noise won’t come right after you start the laptop because the intelligent design of the laptop detects when the fans will be running faster or slower. 

When the laptop is in rest mode, the fans are slower, and when the laptop is busy in multiple activities like video editing or heavy gaming, then the fan will start whirling.

In case of rough and jaggy noise, get ready for a replacement because that can be an indication of a broken laptop fan.

2- Feel the air out of vents

When the fan is running at full potential, it will be blasting out a ton of air. To find that out, you can put a paper, cloth, or your hand in front of the vents to detect the movement of cloth or feel it through your hand.

Putting anything in front of the air vents will help you find the airflow.

Using software program for hardware stats

You can use a variety of paid as well as free software programs that can keep a consistent eye on your entire system to detect any abnormal activity or any glitches in the hardware component.

Having one of such software in your machine allows you to control how components should perform like it should handle the fan speed manually as well as automatically.

Choose one of such applications to keep your system under constant monitoring to prevent any havoc.

Windows Laptops

If you’re a windows laptop user, then there are plenty of applications like SpeedFan, HW Monitor, HWiNFO, Argus Monitor, Real Temp, Wise System Monitor, etc. This software is commonly used and the most popular among these are the SpeedFan and ReamTemp because both of these handle the temperature of the machine as well as the speed of the laptop fan according to the temperature.

Whenever the system exceeds a certain temperature limit, the software detects that and automatically starts the fan to bring the temperature down. For instance, example, a warmth of > 70-degrees Celsius is considered just worrisome but that of > 80-degrees means just stop working immediately.

Some people have sensors in their laptops that are controlled by apps and they are also helpful in such scenarios.

For Mac Devices

Sometimes your MacBook fan can make noise and that can be an alarming situation for you. But nothing to worry about if you can take necessary precautions on time. Mac users can try the iStart Menu application that keeps an eye on all over the device. There is also a free application called Fanny which is a free software widget and that helps you with monitoring or your Mac’s fan status.

Keep one thing in mind that if you’re using the laptop for architect software, video editing software, or intensive gaming, the fan will run faster and you will be experiencing overheating issues along with other abnormalities.

Check for Symptoms

Although every laptop comes with built-in thermal protection and can efficiently detect more heat in certain scenarios. In this case, the system shuts down the system to prevent overheating. But keep in mind that a broken fan of the CPU will result in constantly shutting down and not booting up which can be alarming.

So, to prevent permanent damage to the internal components of the computer you should carefully think about replacing the fans immediately. But to further make sure, open the computer case, ensure the CPU fan is running perfectly. Laptop fans are inexpensive to replace and are also easily available at the local store.

Check The Temperature

In case of no visual inspection, the other thing you can do is to check the temperature of the CPU. For. That, you need to restart the machine and visit BIOS settings from the boot menu during startup. There will be a temperature setting and you need to notice that if it is maximum temperature should be 80 degrees celsius. Check it if is above or less, then determine if it requires replacement.

Keep things clean

The final step towards the welfare of your laptop is to extend the life of your laptop through regular maintenance. SO, you should make sure it is cleaned regularly and make sure you wipe the dust, dirt, and debris off the laptop all the time. You should wipe away grim using a gentle cloth, compressed air to remove stuck dirt, or clogging the fan that can be a primary reason for preventing it from rotating. So, open the case, make sure dust isn’t preventing the fan from working correctly, and then wipe the interior carefully and don’t touch components when the laptop or computer is running.

Finally, with these tips,  you will be able to keep your laptop fan safe with a proper case. So, now you know why the cooling fan is more important than a strapping processor or other hardware components.
