How to Use a Speedfan – How to auto-control fan speed using SpeedFan

Is your computer overheating? If yes, this could be one of the reasons why your PC is lagging. Every PC has multiple moving components that generate heat while in operation. And the harder these components run, the more heat is dissipated. However, if this heat is not regulated, it can lead to overheating.

Overheating can slow down your computer, which can affect the performance and lifespan of your machine or even completely shut it down, which may result in data loss. And if this is the case with your PC, there could only be two main reasons for overheating: either your cooling system has underlying problems, or your computer’s components are overheating to the point that the cooling system cannot handle. So, to ensure that overheating doesn’t occur in the future, you need to fix the cooling system by speeding up your cooling system, and that’s where Speedfan comes in handy.

Not only does Speedfan allow you to optimize your system’s cooling system, but also monitors its performance and provides you with real-time status of your computer including warnings in case of abnormal conditions.

Before we dive into how to use the Speedfan, let’s have a look at what exactly is the Speedfan application and some of the benefits it offers.

What is Speedfan?

SpeedFan is an application geared towards monitoring the status of your computer’s components, and undeniably one of the best hardware monitoring tools. It is a robust, convenient, and reliable program with impressive features that can help you change and control the fan speed of your computer and to check on the temperature of your hard drive, CPU, and motherboard to ensure the entire system maintains cool at all times.

Benefits of using Speedfan program

Amongst the advantages of Speedfan, the most vital is its comprehensiveness. The program has a wide array of impressive features. As aforementioned, it can detect and display the temperature of your motherboard, hard drives, and graphics card. It can also read, monitor, change, and control fan speeds and voltages, and can monitor the status of your hard drive using the SCSI feature or the SMART technology.

This masterpiece also comes with other incredible features and capabilities, such as the ability to set alerts and actions to be prompted when specific parameters under watch get to a set value. For example, if you are monitoring the temperature of your CPU, it can play a sound or popup a notification when it reaches a specific level.

Besides that, this tool has a mind-blowing level of accuracy. You will marvel at its ability to provide accurate data. You can use it to detect wrongly installed heat sinks and other problems that may result in your PC behaving abnormally.

Moreover, Speedfan is free to download and specially designed to support different types of motherboards, chipsets, among other devices. It is a workhorse that’s pretty easy to use and readily available to everyone, including beginners.

How to use Speedfan

  1. The first step before installing the Speedfan program is to check whether it is compatible with your motherboard. However, if it does not support your motherboard, do not fret, you can use the application to monitor or troubleshoot your PC.
  2. If your motherboard supports the Speedfan program, head to your BIOS to disable the automatic fan controls.  This way, the Speedfan, and your system’s fan settings will not clash. Once it’s done, you can now install and launch Speedfan, but don’t open it instantly. Give it a few seconds to scan your PC sensors, and it will display lots of temperature readings for different components of your computer, including the CPU, GPU, and hard drives.
  3. On this step, click on the configure button on your right side. Then open the “options” tab to ensure “Set fans to 100 percent on program exit” is ticked. Then you can set “Delta value for fan speeds” to maximum value, which is 99. This step is crucial as it helps ensure your fans don’t remain at the preceding settings even when the temperatures hit the roof.
  4. Next up, move to the “advanced” tab, and on the drop-down menu, choose the superior chip of your motherboard. Now, look up for the PWM mode, which you need to change to manual. You can use the up and down arrows to change the percentage of the fan speed or enter a value in the menu. However, you need to set the percentage to a value higher than 30 percent to ensure the fan RPM reads accurately.
  5. Now head to the “Speeds” tab to set up automatic fan controls, and don’t forget to check for “Automatically variated.”This tab allows you to find the maximum and minimum values of your fans in your PC.
  6. Now you can go to the “Temperatures” tab to set the temperature which you want your fans to run at and also to set a warning level for each set temperature. So if the temperature exceeds the set warning level, Speedfan sets the PWM back to 100 percent. Moreover, you can check “Show in tray” to get a notification display of the computer component you are monitoring. And lastly, add a Speedfan shortcut to the Start-Up folder to ensure it launches when starting up.

Conclusion

As you’ve seen from our article, Speedfan is a robust and reliable application that can help you to conveniently and easily adjust your build’s fan speeds for the best cooling performance. By following the steps listed above, you should be able to configure Speedfan to be able to monitor your system’s temperature and customize fan speeds for optimal cooling. This is all it takes to keep your system cool when its operating under heavy load.
