Why Does My Laptop Fan Keep Running?

Your laptop fan keeps running non-stop and you don’t know what to do about it! This is a frustrating problem and many people have experienced it. It’s not just your computer fan that has dust build-up, but there are other causes of this issue.

If your fan is running all the time, it may not be making much noise but could still cause damage to your PC and void its warranty if left untreated. Learn how to prevent this problem by keeping things clean in order to keep cool air flowing through your system! This article will teach you why fans run constantly as well as how to stop the problem.

Why Does My Laptop Fan Keep Running Non-stop?

When you set your laptop power settings to high performance, the laptop uses every tool at its disposal to hit the highest speed possible. Throttling can drastically affect the performance of a system. So, when you set your power consumption to High Performance, the laptop will avoid throttling at all costs in the first place.

In the course of avoiding throttling, the fans will run to their full potential. If the fans can already cool the internals effectively, is there really a need for throttling in the first place? Sometimes, your laptop will run coolly, while you type out a document in Google Docs suddenly hear fans start spinning and very loudly at that

Laptop fans can stop working if the heat from the processor builds up. If this heat is not released, it can cause other problems with the laptop. Laptops designed to work with their fans running all the time are subject to this problem.

Here are important reasons why your Laptop fan is running continuously without stopping

Blocked Laptop Air Vent

If your laptop is overheating and the fan running constantly with a loud noise, it’s likely that there is dust and hair blocking the vents. To clean your machine, you’ll need a can of compressed air, a screwdriver to open your laptop and patience. Use the air in short bursts to remove dust and hair from the internal components, particularly around fans and heatsinks.

Running Intensive Tasks like games

Running intensive tasks like games can overwork the CPU and GPU, leading to overheating which in turn causes your laptop fan to run non-stop. Laptop coolers used to be innocuous-looking plates of metal with fans in the base, designed to maximize available airflow. These days they’re covered in LEDs, with variable wind speeds, temperature sensors, and in-built USB hubs.

Coolers are ideal if you use your laptop on a desk or in another static position. They’re an especially compelling purchase for those looking to play demanding 3D games or render video for extended periods of time.

Running Several Apps on your laptop at the Same Time

Running multiple apps on your laptop can overwork the CPU, causing the fan to always run and make a loud noise. Mac users can use Activity Monitor to kill processes that are slowing down the computer or Windows 10 users can edit the startup folder. Linux startup processes can also be tweaked for a quieter laptop fan.

Dust in the Air Vent

The laptop fan will run abnormally when the air vents are blocked. Cleaning the air vents will fix this problem. Check for lumps of dust or small debris that may clog up the air vents and clean as needed.

Outdated BIOS

If your laptop fan is always on, it’s likely because of an outdated BIOS. To fix the issue, you’ll need to update your BIOS. You can find updated BIOS files from your laptop manufacturer’s website.

Overclocking your Processor

One of the popular causes of your computer fan constantly running is when the CPU or processor is overclocked. To see what programs are using your processor the most, press CTRL + ALT + DEL keys on your keyboard and choose “Task Manager”.

The first view (above) shows you, at a glance, what is your current processor workload (under the CPU column). If these are not essential Windows services, you can simply right-click it and select “End task”. If it is not possible to end a task because you are using it, try to do either of the two things: Reduce the usage of one or more of the tasks; Use tasks alternately.


Overheating is a common problem with computers, and can lead to fan problems and possible fan failure. Canned air or a small vacuum can be used to clean the computer and improve ventilation.

Malware Attack

Malware attacks can consume large amounts of computer resources and storage. A malware detection and removal tool from a reputable provider is your strongest ally in the fight against these attacks. Without malware chewing up your resources, your fans will have a much easier job.

Background Processes

A high CPU cycle rate indicates an application or service is using too much of the computer’s resources. To reduce the CPU cycle rate, you can disable background services or apps. Disabling Geolocation Service was successful in reducing the CPU fan noise but it restarted later.

How to Stop Laptop Fan from Running All The Time?

A laptop fan is essential for the health of your laptop device, but when it runs all the time, it usually indicates that there’s a problem with your computer. Here are some practical tips to help fix your laptop fan that keeps running.

1. Always Clean your laptop Air Vent

Laptop air vents can become blocked, leading to overheating and fan noise. To clean the vents, turn off your laptop and use a portable vacuum cleaner. Make sure to clean all vents on your device.

2. Always Check your processor’s utilization

To see what programs are using your processor the most, press CTRL + ALT + DEL keys and choose “Task Manager”. If these are not essential Windows services, you can simply right-click it and select “End task”. If it is not possible to end a task because you are using it, try to do either of the two things: Reduce the usage of one or more of the tasks

Use the tasks alternately. For example, if you are editing a photo, shut down your internet browser when doing this. When you’re done, shut down the photo editing software and launch the browser window again

3. Adjust Your Laptops Power Settings

To set your power settings, first type “power settings” in your Windows taskbar and select the result “power & sleep settings”. In the new window, click on “Additional power settings”:

Under Processor Power Management – System Cooling Policy: Turn the options to “Passive” from “Active”, and have in mind that doing this will result in your laptop slowing down your processor instead of turning the fan on.

4. Don’t forget to check for Windows updates

Windows updates can slow down your computer and cause the fan to run at all times. You can pause updates for 7 days or indefinitely. Checking for Windows updates is a good way to keep your computer healthy and running smoothly.

5. Update System Settings

Your system settings will always tell your computer to run its fan at a certain speed, whether or not it is necessary. To stop your fan from always running and wasting energy, you should always update your system settings.

6. Use A Laptop Cooling Pad to help cool your Computer

Laptop cooling pads are beneficial because they have internal fans that work better and faster than those on your laptop and maintain a low temperature. Clip-on vacuum fan coolers literally suck the hot air straight out of your machine.

Use a laptop cooling pad to help cool your computer. A laptop cooling pad is an effective way to reduce the temperature of your computer. Laptop cooling pads can be used in place of an external cooler for laptops that are constantly hot or noisy.

7. Use Software to Adjust your computer Fan Speed

There are different software options available to adjust computer fan speeds. SpeedFan and smcFanControl are two popular options. If your laptop fan is still noisy or you’re unwilling to open the device, speak to an expert for help. If you bought online or your retailer is too far away to visit, PC repair shops may be a cheaper option than buying a new laptop

8. Always Update BIOS

Always update BIOS to ensure optimal system performance. HP provides BIOS updates for computers that are registered and have the latest software installed. Click Apply Update Now if there is a new BIOS update available, or wait for the update to start automatically.
