How To Check your Laptop Fan is Working Or Not (2022)

Laptop fans are essential for keeping your computer system’s internal hardware cool. The fan absorbs heat from the motherboard and processor and blows it out through the fan vents, much like a radiator does when it blows hot air out of a car engine.

I will tell you the very easy way to How to check your laptop fan is working or not.

If your fan is inaudible, you can’t feel the air rushing out of the vents, and, most importantly, your laptop is getting heated regularly, it’s likely that the fan has ceased working properly. And something needs to be done about it. Yeah?

The fan is vital in extending the existence and value of a PC system, as a warm PC plays poorly and may purpose quite a few issues, which include common abrupt shutdowns, software crashes, and, with inside the worst-case scenario, harm to the PC’s hardware.

Overheating can purpose critical malfunctions or harm to the system’s inner components. Checking the fan in your pc is easy and need to be carried out on a common basis. To keep away from any difficulties, make certain to update the buggy fan.

I will tell you How to check your laptop fan is working or not.

The Importance of Fans

A fan’s obvious job is to cool down the system, which could be any system. The laptop fan, in our case, does the same thing to keep the laptop’s internals ventilated. For the sole purpose of maintaining the laptop’s peak performance. Because this is an electronic physical component, it can heat up quickly and sabotage the system’s performance. As a result, all programmes will slow down or crash.

The main problem with a faulty fan is that it may cause harm to other parts of the laptop. Because certain components in the laptop are unable to withstand the heat generated by the faulty fan. Your entire computer is at risk of breaking down unless you fix the heating problem.

The core of the subject is that a laptop fan is critical and must function properly. The actual question is: how will you know if there’s a problem with the fan? That’s what we’ll look at right now.

So keep an eye on the fan

Keep an ear out for noise

The very first thing you can do is listen to your laptop’s fan to see if it’s working properly. Yes, try to isolate the sound of a running fan because, as previously said, a running fan makes a moderately loud sound. When operating on a laptop, most of them make a certain noise.

Place your ear near the bottom of the laptop, behind the keyboard, in a calm area. A fan in most current laptops only works occasionally, not all of the time. The fan kicks in while you’re doing processor-intensive chores like picture editing, gaming, or video editing. Because processor-intensive tasks might cause the device to overheat quickly.

As a result, if your laptop doesn’t make any noise when you turn it on, it’s because it’s running at the slowest feasible speed. To optimize battery performance and efficiency, manufacturers frequently set the fans to operate only when the battery is under stress, allowing the cooling process to proceed more quickly.

Start streaming a 4K video or play a high-definition game to push your laptop fan to turn on. These will put some pressure on the laptop and cause the fan to turn on.

It’s possible that your fan is faulty if it creates jagged pulsating or shrieking noises when you’re listening in.

Look for Air

There’s no need to worry if you couldn’t hear the fan. Laptop exhaust can be found on the left, rear, or at the bottom of the laptop.

You may locate it by placing a piece of paper in front of the fan output; if the paper is blown even slightly, it will indicate that the fan is operating, or you can feel the heat coming from the air vents with your bare hands.

Modern compact computers with small fans may not be willing to blow away a piece of paper. However, these two methods are the simplest and most basic for physically inspecting a laptop’s fan. There are a variety of other methods you can use to determine whether or not your fan is working.

Keep an eye out for mistakes

If your laptop repeatedly restarts without notice, slows down, or shows you a Blue Screen of Death, there could be a problem with your fan (BSOD).

Even if the fan is flowing air and appears to be operating, it is connected to the heatsink cooling system, and difficulties with it could indicate problems with other cooling system components.

Using an application for testing

You can use a software program utility to test in case your computer fan is running or not. There are many programs to be had at the net which could variety from providing you with simply the temperature and fan pace to superior functions like controlling the fan pace and different hardware evaluation information.

Windows-based testing

SpeedFan is the most popular application for the Windows platform. It can track temperature from a variety of sources and adjust fan speeds automatically or manually in response to the system’s temperature.

With SpeedFan, you can monitor practically all of the other sensors on your laptop, including hard drive temperature and ambient case temperature, in addition to the CPU temperature. In the charts tab, you can also switch to the detailed view, which displays temperature charts for selected components.

Other software tools you can try are HWiNFO, Argus Monitor, and Real Temp.

Using a Mac for testing

On a Mac, the iStat Menu provides fan statistics as well as a plethora of other functions such as the Battery Sensor, Hard Drive, Palm Rest temperature, and a plethora of other options.

Fanny widget for macOS is available for download; I’ve been using it for quite some time. Its primary purpose is to display the current CPU temperature and fan speed. The programme is easy to use, efficient, and starts automatically when the computer boots up.

Ubuntu Linux for testing

You’ll need to install Im-sensors and fan control packages to measure the fan speed and temperature of a machine running Ubuntu Linux.

Im-sensor should be installed as follows:

  • install Im-sensors sudo apt-get
  • Now use the command to execute the programme.
  • sensors-detect sudo
  • For fan speed, use the following formula:
  • grep fan | sensors
  • The fan speed will be displayed as a result of the command.


I attempted to illuminate some fundamental strategies for evaluating your laptop fan. I included the software solution I had on hand to perform the fan testing to make it a little more interesting.

You’ll be able to estimate the value of a fan in terms of laptop performance and longevity. You should also keep it in excellent working order. This will keep the laptop running smoothly and reliably.

I hope you better understand now how to check your laptop fan is working or not.
