How To Control CPU Fan Speed?

Controlling your CPU fan speed is key for your computer’s performance and longevity. Whether you’re a gamer needing to cool down during intense sessions or just want to reduce noise, adjusting the fan speed helps. This guide explains why fan speed matters and provides simple, step-by-step instructions to adjust it. We’ll cover methods like BIOS settings, software solutions, and third-party applications. This will help your computer run efficiently and stay quiet when high power isn’t needed. Let’s get started and learn how to manage your CPU fan speed.

How To Identify Which Type Of CPU Fan You Have?

There are a couple of ways to identify the CPU fan you have:

1. Physical Inspection Of The Computer

To manually identify the type of CPU fan, you’ll need to perform a physical inspection:

  • Power Down And Unplug: First, make sure your computer is completely turned off and disconnected from any power sources to ensure safety.
  • Open The Computer Case: Use a screwdriver to remove the screws securing the side panel of your computer case. Gently remove the panel to gain access to the internal components.
  • Locate The CPU Fan: Search for the CPU cooler, which is generally a prominent metal heatsink with a fan mounted on top, positioned over the CPU.
  • Identify The Fan Type: Carefully examine the fan and its mounting assembly. Look for any identifiable information such as model numbers, serial codes, or brand logos directly on the fan or its adjacent parts. These identifiers are key in determining the exact model and type of your CPU fan.

2. Utilizing System Information Software

For a non-intrusive way to identify your CPU fan, you can use software solutions that provide detailed hardware analysis:

  • System Information Tool (Windows):
    • Accessing The Tool: Press the Windows key, type “System Information,” and hit Enter to open the application.
    • Finding CPU Fan Information: Within the System Information window, navigate to the ‘Hardware Resources’ or ‘Components’ sections to find details related to your CPU and cooling system. Some systems may list the fan’s specifications or type.
  • CPU-Z (Third-Party Software):
    • Download: Go to the official CPU-Z website to download the application. Always ensure you download from a reputable source to avoid security risks.
    • Installation and Overview: Once downloaded and installed, open CPU-Z. The software will display multiple tabs each dedicated to different components of your system. While CPU-Z primarily focuses on CPU and motherboard information, it might indirectly provide clues about the fan type through the motherboard chipset or CPU power specifications.

These methods will enable you to determine the type of CPU fan installed in your system, using either direct physical inspection or detailed software analysis, ensuring you have a comprehensive understanding of your computer’s cooling setup.

Why is controlling CPU fan speed important?

Controlling CPU fan speed is important for balancing temperature and noise. CPUs generate heat, and fans help cool them down. But, fans can be noisy when they spin fast. By adjusting fan speed, you can keep the CPU cool during heavy use by increasing the fan speed. During lighter tasks, you can slow the fan down to reduce noise. This helps maintain a balance between cooling and noise levels.

How can I check my CPU temperature?

You can check your CPU temperature using the BIOS or third-party software. The BIOS method is quick but only shows the temperature at startup. For ongoing monitoring, use free programs like Core Temp, HWMonitor, or HWiNFO. These tools display your CPU temperature and provide additional details like fan speed and core temperatures.

Does overclocking affect CPU fan speed requirements?

Overclocking affects CPU fan speed requirements because it makes the CPU work faster, generating more heat. To prevent overheating and potential damage, the fan must work harder, often spinning faster and becoming louder during demanding tasks. You might need to adjust your fan curve in the BIOS to ensure proper cooling at higher clock speeds.

How do I troubleshoot CPU fan speed issues?

CPU fan speed issues can arise from dust buildup, poor ventilation, or BIOS settings. To fix this, first turn off and unplug your computer, then clean the vents and fan blades with compressed air. Ensure your computer has good ventilation. If the fan is still noisy or slow, check your BIOS for fan speed settings. If the problem persists, consider replacing the fan.

Can I control CPU fan speed without accessing BIOS?

You can control fan speed directly through the BIOS, but there are other options as well. Some motherboards come with manufacturer software for fan control, available on their support page. Third-party programs like SpeedFan can also adjust fan curves based on CPU temperature, but they need compatible motherboard hardware. If these software options don’t work, you’ll need to use the BIOS for adjustments.


Controlling your CPU fan speed is key for better performance and longer computer life. This guide has covered methods such as BIOS settings, software tools like SpeedFan, and hardware fan controllers. Managing fan speeds helps with cooling, reduces noise, and prevents overheating. This leads to a smoother and more efficient computing experience.
