Simple Tips to Fix a Laptop Fan That’s Running Constantly


Having a laptop fan that’s consistently running can be a real nuisance. Not only is it a source of distracting noise, but it can also have a serious impact on the performance of your laptop. If your laptop fan is consistently running, there are a few simple fixes that you can try in order to get it running normally.

The first step you should take is to ensure that your laptop is free of any dust and debris. Laptop fans can quickly become clogged with dust and debris, causing them to run constantly. Use a can of compressed air to gently blow away any dirt and debris from the fan. If you don’t have a can of compressed air, you can use a soft brush to gently remove any dust and debris from the fan and the vents of your laptop.

Quick Tip for Fixing a Laptop Fan That’s Running Constantly

If your laptop fan is constantly running, it can be a sign of overheating and cause serious damage over time. Here’s a simple and effective fix: use a can of compressed air. Compressed air can be used to remove dust and debris from the fan that’s blocking the airflow and causing it to work harder than necessary.

Start by shutting down your laptop and unplugging it. Be sure to turn it completely off, since running a fan while it’s still on could void your warranty. Once it’s off, you can inspect the fan to make sure there isn’t any obvious blockage near it. If there is, you can use a can of compressed air to blow it away.

Once the fan is free of any blockage, you can use the can of compressed air to gently blow away the dust and debris. Be sure to keep the can at least 12 inches away from the fan and move it in a steady motion to ensure the debris is thoroughly removed.

Once the fan is free of debris, you can turn your laptop back on and see if your fan is still running constantly. Chances are it won’t be, but if it is, you may need to take it to a professional repair shop.

By using a can of compressed air around your laptop fan, you can quickly and easily fix a fan that’s running constantly and preserve your laptop’s performance.

Assess and Inspect the Laptop

Is your laptop giving you trouble due to its fan running constantly? No need to panic. Here are some simple tips to help you assess and inspect the laptop to diagnose what’s wrong and fix it.

  1. Check the laptop’s temperature monitor – First, note the temperature of your laptop when the fan is running. If you find that the temperature exceeds 50 degrees Celsius, it’s likely your laptop is overheating. Check if the fan is emitting too much noise and if the laptop is getting hot near the fan vents.
  2. Examine the interior condition – Open up the laptop and look inside to check if any dust particles have accumulated on the fan or around the heat sinks. This can be a factor hindering the fan from cooling the laptop and making it run constantly.
  3. Check your other hardware components – Sometimes, rotating fans placed next to the hard disk can push air into the laptop and help keep it cool. Make sure that all other fans are functioning properly.
  4. Clean the vents from dust – Use a multi-purpose brush, a vacuum, or compressed air to remove dust from the fan vents. Make sure you do this step gently and carefully, as forcefully removing dust can damage the laptop’s interior.
  5. Replace the fan or other hardware components – If none of these steps have solved your issue, consult a laptop repair shop. In some cases, software and hardware elements may need to be replaced.

Follow these steps and your laptop fan will start running smoothly again. If you have any further questions, don’t hesitate to reach out to a professional.

Is your laptop fan running constantly? Here are some simple tips to help you fix it:

1. Check Cooling System Settings

The first step is to check the cooling system of your laptop. This can usually be done through your laptop’s BIOS. In your BIOS, see if the fan speed is set too low; if so, you need to increase it. You can also check the temperature settings that determine when the fan will start running. Make sure they are at the right levels so that the fan won’t run constantly.

2. Clean The Fan And Heat-sink

If your laptop is running too hot, then cleaning the fan and heat-sink is a good way to help fix it. Shut down your laptop, and then use some compressed air to blow any dust and debris out of the laptop. This will make sure the fan and heat-sink are working efficiently.

3. Change The Thermal Paste

Replacing the thermal paste will make sure that heat from the CPU is efficiently dissipated into the heat sink. You can do this yourself, or take it to a computer repair shop if you’re not comfortable tackling the task.

4. Check The Power Settings

Your laptop has several power settings that determine how it will behave. You should check each of these settings to ensure that your laptop is running efficiently and not forcing the fan to run constantly. You can also make sure that your laptop is set to turn off after a while, so the fan won’t need to run continuously.

If you’ve followed these simple tips, you should find that your laptop fan is no longer running continuously. However, if the problem persists, it’s probably best to take your laptop to a computer repair shop, who can diagnose the issue and help you fix it.


In conclusion, fixing a laptop fan running constantly can be a difficult task without technical knowledge. However, with the simple steps outlined above, anyone can turn off their laptop fan and get more comfortable using their laptop. If the problem persists, you should take it to a professional for further repairs. With these simple tips, you will soon be able to reclaim your laptop’s quiet operation and enjoy its full potential.
