SpeedFan is a free system monitor for Windows. This program uses the hardware monitoring chips found on most motherboards so you can see readings from some of the vital components of your computers such as your CPU and hard drive temperatures, fan speeds and voltages. It supports SCSI drives and network computers.

Many programs monitor your computer’s temperature, but one of the most popular is SpeedFan by Alfredo Milani. Alternative programs include Core Temp, HWMonitor and MSI Afterburner.

How does SpeedFan work?

SpeedFan works like a standard Windows application running in system tray. By default, it doesn’t do anything until certain parameters are met, such as the CPU reaching a certain temperature, or using disk space to a certain extent. It will then start the program’s fan to lower the temperature or warn you with a pop-up message.

Program worthless and performs a very useful function. It’s great for keeping your computer running in optimal conditions without constantly monitoring it yourself or resorting to a third-party taskbar.

SpeedFan Features

Temperature sensors. SpeedFan can access temperature sensors and other features specific to your computer’s hardware. Depending on the hardware installed on your PC, SpeedFan can use a very complex set of options, such as advanced graphics card monitoring or hard drive status indicators.

The program can read from SMART capable hard drives their current temperature and overall health. If your hard drive fails or has a firmware error, SpeedFan will usually find the problem.

you also can switch on switch off some hardware sensors work while Speedfan is running. This allows you to perform some initial on-demand tests without restarting your computer, such as when overclocking new hardware or checking that specific sensors are within normal ranges.

networked computers. SpeedFan can work with several remote computers at the same time; this feature is useful mainly for LAN parties or when you want to control multiple computers using only one keyboard, mouse and screen. You can check the status of other computers by connecting to them remotely.

Fan speed controllers. SpeedFan can provide dynamic fan speeds for almost any supported hardware, including built-in laptop fans.

Sensor configuration. SpeedFan comes with an extensive options panel that allows you to customize all of its many options. The tool allows you to set your own temperature limits for each sensor, enable/disable readings from specific hardware devices, or even limit fan speed based on temperature.

Is SpeedFan easy to use?

SpeedFan configuration menu quite extensive, although finding the right options should be no problem for advanced users, or at least those who know what they’re looking for. In addition, it can be configured to run at startup and while the program is running. The last option should allow you to save CPU usage by keeping an eye on the temperature of your hardware.

The application also allows you control any connected fans – including those connected with a splitter cable – and change their speed accordingly. In addition to this, the app has a network monitoring feature that can be used for remote access.

What can’t SpeedFan do?

This is a very versatile application, but those who are looking for something that includes built-in overclocking option is disappointing. Also, the program may take some time to learn as there are many options and the current user interface is quite dated.

Is Speedfan safe?

If you use the program correctly, then there is no need to worry about any security issues. All configuration changes are saved in a specific file, and the program only runs when you tell it through the taskbar menu.

Is SpeedFan Free?

Yes, this is an app. absolutely free and can be downloaded for free. During operation, SpeedFan dynamically adapts to the hardware installed on your computer; it does not require any special installation steps and can work as a portable application.

Alternatives to SpeedFan

There are many other applications that you can use to monitor hardware such as Core Temp, HWMonitor and MSI Afterburner.

Main temperature: This program is designed to measure the temperature of your motherboard, CPU and GPU. It can display the current frequency of each core along with the corresponding voltage. Core Temp has different skins to change the appearance of the program. In addition, it allows you to change options such as color tint, opacity level, font size, etc., but there are no additional options.

HWMonitor: This program has a tabbed interface that allows you to monitor your hardware’s sensors and fan speeds in an easy-to-understand manner, then save the results as a .csv file for later use. You can also control any specific register values ​​on the motherboard by accessing the input field.

MSI Afterburner: This is a graphics card overclocking utility. It allows you to set fan speed, core and memory clock speeds for supported Nvidia or AMD cards, as well as voltages and other options.

Easily monitor the status of your PC

In conclusion, SpeedFan is lightweight system monitor for Windows, designed to monitor the temperature of your processor and hard drive. It has quite a few useful features such as the ability to control the fans connected to your computer, reboot/shutdown options, and more.
