How to use Speedfan to Control Computer Fan Speed

Do you want to know how to use SpeedFan to control fan speed on Windows 11/10 laptop or PC?

Well, Speedfan is a hardware monitoring tool for Windows OS that can be used to read the Laptop/PC’s voltage and fan speed, and temperature of CPU, motherboard, and hard disk.  Although, it allows to change the fan speed.

In this guide, I’ll show you how to use SpeedFan on Windows 10 to control fan speed.

Most people are often worried about their PC/Laptop temperature when it goes high. Though, Windows doesn’t provide any option to see the system fan speed and temperature. But, there are plenty of tools available on the web for free.

When it comes to the CPU temperature monitor tools, Speedfan is coming in the first position because of its popularity and features.

However, nowadays you don’t need to control your computer’s fans manually with software or tools because almost all computers have inbuilt fan controls.

But still, if you want to control the fans manually, you can use SpeedFan software on your Windows machine.

Inbuilt fan controls automatically adjust the fan speed according to the system heat. When the system generates more heat (obviously under high load), fans speed will be increase automatically. Similarly, when the CPU is idle and system temperature is reduced, fans speed will also be reduced.

The auto adjustable fan speed reduces the noise and power consumption.

What is Speedfan?

Speedfan is software to monitor computer temperatures. It can monitor the CPU temperature of each core, Hard Disk temperature (SATA and SCSI), fan speed, and voltages.

Every computer system has an inbuilt hardware monitoring system. The hardware monitoring system works with digital temperature sensors. Speedfan can access these sensors and provides the information to see the status of your system.

Most people are using this tool to just see the status of the computer. But, you can do a lot more with it. If your PC often hangs under heavy load, then this tool may help to let you know what happens when your computer is under heavy load. So, you can easily find the problem.

Moreover, you can control the fan speed of your PC with it. You can select the manual or automatic speed. The automatic fan speed option will control the fan speed according to the PC temperature. However, this feature is inbuilt in all modern systems.

Apart from this, you can access the hard disk drives status with it. It uses S.M.A.R.T (Self-Monitoring Analysis and Reporting Technology) to diagnose hard disk failures.

Features of Speedfan software

The main features of SpeedFan are given below:

• Temperatures – This tool can access the temperature sensors available on the motherboard, graphic cards, chipset, CPU, and power supply.
• CPU Temperature – Nowadays all CPUs come with multiple cores and all cores can provide the internal temperature. Speedfan reads and provides the information from each core.
• System Fans – Fans are used to reduce the computer’s internal temperature by circulating air. CPU under load needs more power and more power leads to more heat. So, fans flow hot air out of the system. Speedfan allows us to read the fan speed in RPM and can change the speed according to the real-time temperature.
• Voltages – The software is also able to read the system voltages. You can find the problems regarding the voltage.
• Hard Disk Drives Status – Hard Disks (SATA and SCSI) can report their status, temperature, and health to the systems with S.M.A.R.T (Self-Monitoring Analysis and Reporting Technology). This status information helps to identify future hard disk failures. Speedfan can also access the hard disk status and health information. It also offers to perform an in-depth online analysis of the hard disk.

Temperature symbols and meaning

1. Tick – The system is running under normal temperature.
2. Down Arrow – Blue color down arrow indicates that the system is running at a low temperature.
3. Up Arrow – Red color up arrow indicates that the system is running at high than normal temperature.
4. Flame – The flame icon indicates that the system is running at a hot temperature. However, you don’t need to worried about if the temperature is less than 85 degrees Celsius.

How to use Speedfan to Control Fan Speed

Speedfan offers automatic and manual fan speed options. However, an automatic fan speed feature is inbuilt in all modern PCs. But, SpeedFan also offers this option as well.

Automatic fan speed helps to reduce fan noise and power consumption. Because the fan speed will be changed according to the temperature.

Fan speed will be increase automatically when the system heat up. And the speed will be reduced when the system is cool.

Before using this option, you need to check whether your motherboard is compatible with Speedfan software or not. Open http://www.almico.com/forummotherboards.php link to see the list of the motherboards supported by the software.

Note: Disable inbuilt automatic fan controls on your PC/Laptop from BIOS to avoid conflicts between the system program and SpeedFan.
