How to Take Charge of Your Computer’s Cooling: A Guide to Controlling Fan Speed on Windows 10

Just as we humans break into a sweat when temperatures rise, our computers have a built-in mechanism to cool off too! Whether you’re rocking a high-end gaming rig or a basic laptop, every PC has an inbuilt cooling system featuring fans. The cooling fans frankly may be loud and noisy at times however they have a vital role in maintaining the integrity and health of your PC. Likewise, for prolonging the PC’s health the central processing unit has a predetermined upper capacity on the temperature, the computer shuts down when the PC exceeds the set limit. This feature, known as “thermal monitoring,” and the fan speed has a vital role in facilitating this process.

Irrespective of their dimensions, computers generate heat as they utilize electricity and circulate it through their circuits. The computer fan’s function is to usher cooler air into the computer to help cool down the heated circuitry, with a particular focus on the CPU. In the absence of a thermal monitoring capability, such overheating could potentially lead to a fire. In this guide, we will be looking at how to control the fan speed on your PC with Windows 10.

Understanding Your PC’s Cooling Mechanism

Upon booting your system, you might have noticed that your fans start humming louder, only to quieten down once the system has fully started. These fans work harder when you’re consuming more system resources, say, if you’ve opened numerous tabs on Chrome.

So how do these fans know when to kick into high gear and when to relax?

The Magic Behind Fan Speed

These fans are pretty smart. They come with built-in sensors that consistently monitor your system’s temperature. When the temperature crosses a certain threshold, your fans spring into action, spinning faster to bring down the heat.

Your PC or laptop chassis is designed to ensure proper airflow, which is why it’s crucial to keep vents unblocked. If your system continues to perform heavy-duty tasks, the fans will run to stabilize the temperature.

The Delicate Balance

These temperature sensors, their set limits, and the various fan speeds are not accessible by users. This is mainly because it’s tough for most users to accurately gauge their system’s temperature and decide when it’s time to adjust fan speeds.

Moreover, if your fans run continuously, your PC ends up consuming more energy, which might overheat the adapter. Maintaining a balance between keeping a system cool and not overloading it is an intricate task.

But what if you want to take matters into your own hands? Let’s find out how.

Steering the Wheel: Controlling Fan Speed on Windows 10

Before we dive in, here’s a disclaimer: controlling your fan speed comes with a risk. Overheating your PC or laptop can permanently damage hardware to the point where it must be replaced. So, proceed with caution!

To manage your fan speed, you’ll need a third-party app, which would depend on your hardware. Here, we’ll discuss two apps that can detect your fans and let you adjust their speed: SpeedFan and HWiNFo.

Taking Control with SpeedFan

First up, let’s learn how to control fan speed using SpeedFan.

Time needed: 25 minutes

  1. Install SpeedFan

    Download the SpeedFan application and proceed with the installation process. Once installed, run the application.

  2. Access Configuration Settings

    In the main window of the SpeedFan application, locate and click on the ‘Configure’ button. This will open a new window.

  3. Navigate to the Fans Tab

    In the newly opened configuration window, find and click on the ‘Fans’ tab.

  4. Detect Fans

    Wait for the SpeedFan application to automatically detect and list all the fans in your system.

  5. Select the Fan to Control

    From the list of detected fans, select the specific fan you want to manage.

  6. Utilize the Response Curve

    The final step is to use the response curve feature in the application to adjust and control the fan speed.

Understanding the Response Curve

The response curve serves as a map correlating heat with fan speed. As your system runs hotter, the fans run faster.

Taking the Reins of Fan Speed with HWiNFo

Next, let’s explore how to control fan speed using HWiNFo.

  1. Run the app and click Sensors on the main window.
  2. Confirm the pop-up message.
  3. A new window will open listing the various sensors on your system. Look for the fan button at the bottom and click it.
  4. A new window will open listing up to three fans. Select one of the active fans.
  5. Click ‘Set manual’ to manually set the fan speed.

Unlike SpeedFan, HWiNFo doesn’t map the speed to your PC’s temperature, so extra caution is necessary. Make sure to find a way to monitor the temperature of your CPU and GPU to prevent overheating.

Conclusion

Taking control of your PC’s fan speeds can give you a hands-on approach to managing your system’s temperature. However, it’s important to tread carefully to avoid overheating and potential damage to your PC. We hope these steps have guided you through the process, and we’re eager to hear about your experience. So, let us know in the comments if this worked for you or if you have any questions. Remember, the power to cool down your PC is now in your hands.

Overusing or mismanaging your PC’s fan speed can lead to a number of issues. High fan speed usage over long periods can lead to wear and tear of the fan components, reducing their lifespan. Moreover, by manually overriding your fan speeds to stay low, you could inadvertently cause your system to overheat, which can lead to hardware damage and decreased performance. Hence, while managing fan speeds can improve system performance and reduce noise, it should be done cautiously to avoid potential harm to your PC.
