How To Control PC Case Fan Speed? [All Methods]

Learn different ways of controlling your case fan speed through BIOS/UEFI settings, hardware adjustments and software controls.

Controlling case fan speed is essential for maintaining optimal cooling and noise levels in your computer. Adjusting fan speeds can help you strike the right balance between efficient cooling and a quiet system. Therefore, it is important to learn about how to control case fan speeds so you can start adjusting them accordingly. 

Key Takeaways  

  • Adjusting case fan speed is crucial for maintaining a balance between efficient cooling and a quieter computer environment.
  • You have various options for fan RPM control, including BIOS settings, fan controllers, and software tools like SpeedFan or MSI Afterburner, allowing you to choose the method that best suits your needs.
  • Continuously monitor your system’s temperatures to ensure they remain within safe limits while adjusting fan speeds, optimizing performance, and preventing overheating.


Here are some things you need to take care of before you begin the process of setting up your fan speed: 

  1. Ensure your computer is turned off and unplugged from the power source before making any hardware adjustments. 
  2. Depending on your chosen method, you might need fan control software, a fan controller, or a motherboard with PWM (Pulse Width Modulation) support. 
WARNING: If your case fans are making noise even after you adjust their speeds, you might need to clean them.

How Can You Control Case Fan Speed?

In this section, we’ll go over different methods to control case fan speed, which are mentioned below. 

  1. BIOS/UEFI Settings 
  2. Fan Control Software 
  3. Fan Speed Controller Hub 
  4. External Fan Speed Controller  
  5. Control Panel

BIOS/UEFI Settings  

Many motherboards allow you to control case RPM directly through the BIOS/UEFI settings. Read our detailed guide for accessing BIOS in Windows 11.

Here’s how: 

  1. Restart your computer and press the appropriate key (usually Del, F2, or F12) during startup to access the BIOS/UEFI settings.

  4. Save your changes and exit the BIOS/UEFI. Your fans should now operate at the desired speed. 

Fan Control Software 

Using fan control software can be an effective way to adjust your case fan speeds without the need for additional hardware.

Here’s how to control fan speed with three popular software options:

Using SpeedFan

  1. Visit the official SpeedFan website and download the latest version. Install the software on your computer.

Using MSI Afterburner

MSI Afterburner is primarily designed for overclocking graphics cards but also allows fan speed control for case fans if your motherboard supports it.

  1. Visit the MSI website or other reputable sources to download MSI Afterburner. Install the software on your computer.
  2. Open MSI Afterburner. By default, it will display information about your graphics card.
  3. Click on the “Settings” button in the bottom-right corner. In the settings window, select the “Fan” tab.

  5. You can now set a custom fan curve by clicking the “Curve” button. Drag the points on the graph to specify fan speeds at different temperatures. Click “OK” to apply the curve.
  6. Click “Apply” in the settings window to save your fan speed adjustments.
  7. Keep an eye on your system’s temperatures while MSI Afterburner automatically adjusts fan speeds according to your custom curve.

Using HWMonitor

HWMonitor is primarily a monitoring tool, but some motherboards may allow limited fan control through it.

  1. Download HWMonitor from a reputable source and install it on your computer.
  2. Open HWMonitor. It will display various temperature and voltage readings for your hardware components.
  3. Look for the “Fans” section in HWMonitor. It should display the current fan speeds of your system.
  4. HWMonitor may provide basic fan control options, such as setting a fixed fan speed. However, not all motherboards and systems will support this feature.
  5. If your motherboard supports fan control through HWMonitor, you can typically set a fixed fan speed by selecting the desired fan and entering a value or percentage.

Fan Speed Controller

A fan speed controller hub is a device that allows you to control multiple fans at once, often with a remote control. Also, read our guide on how to fix case fan not spinning, but light works. 

Here’s how to use one: 

  1. Purchase a fan speed controller hub suitable for your needs, ensuring it can accommodate the number and type of fans you have. 
  2. Follow the manufacturer’s instructions to install the fan speed controller hub. Typically, you’ll connect your fans to the hub, which is then connected to the power supply. 
  3. Many controller hubs come with a remote control that allows you to adjust fan speeds easily. Use the remote to increase or decrease fan speeds as desired. 
  4. Regularly check your system’s temperatures to ensure they remain within safe ranges while adjusting fan speeds. 

Control Panel 

While you cannot directly control fan speed via the Control Panel, you can adjust power settings that may indirectly affect how your fans operate.

This method focuses on configuring the power plan settings:

  1. Press Win + X and select “Control Panel” from the menu that appears. Alternatively, you can search for “Control Panel” in the Windows search bar.

  4. Expand the “Processor power management” section and adjust the “System cooling policy.” You may have two options: “Active” and “Passive.” Active cooling will make the fans run at higher speeds to cool the system more aggressively, while passive cooling may allow the system to run quieter by using lower fan speeds when possible.
