A free fan monitoring software

Speedfan is designed to monitor the health of your hard drives, the temperature of your hardware, and the speed of your fan. At first glance, the interface is intimidating, but behind that is a powerful application that’s ready to troubleshoot the most difficult of computer issues. There’s more functionality than the default Windows software and your hardware’s bios.

PC health monitor

Speedfan is a handy tool that allows you to monitor your computer’s health and adjust the speed of your fan. The application is free and can help you keep your system running at peak performance.

The changes made recently have enabled the software to measure the health of more recently released hardware such as the Intel X79 and various other CPUs. As new items are released, and changes need to be made to the app, updates will follow to keep the measurements displayed accurately.

The program is relatively light on resources, only using them to read the current details of your case temperature, fan speed, and hard drive health. If used correctly, this application can extend the lifespan of your computer, and it’s internal components.


Speed Fan has an intensive interface that takes time for you to figure out before you start pressing any buttons. The first impression and launching the downloaded file is scary and may turn you away if you have no prior computer knowledge. Fortunately, there are Speedfan tutorials.

Monitor PC health

One of the main uses for SpeedFan is to monitor the health of your computer’s hardware. Mainly this is to ensure that no component overheats, but it can also display fan speed and observe the status of your hard drives. Over time your PC can break down or gather corrupted files that need to be fixed after using software like this to identify it.

Adjust fan speed

The other main use of this application is to control fan speed and change how fast the blades spin, adjusting the wind speed, and the rate of temperature changed within your PC case. By turning your fan onto a higher speed, you can cool down your components faster and provide more room to overclock them.

Stress test

When using SpeedFan in conjunction with another application such as Prime95 Anchor text, you can test the limitations of your computer, and monitor the effectiveness of the new PC you’re building. The combination of these tools are ideal of seeing how far you can push your system before you start damaging it.

Troubleshoot issues

For experienced users or anyone with some familiarity with software like SpeedFan, this application is a handy way to troubleshoot issues with your computer, and it’s various components thanks to the monitoring aspect. This can take a while to understand if you’re trying to troubleshoot for the first time, but there are many video guides available.

Requires admin rights

Every time you launch SpeedFan you will be asked for administrative permissions. This is required for the software to display the details from your computer components and cannot be avoided. This is the most annoying aspect of the software.


SpeedFan is known for being an intensive software, but with a little bit of patience and some guides you can find online, you’ll soon be able to monitor and keep your computer in the best possible health.


If SpeedFan isn’t your choice of PC health monitoring and fan controlling application, there are several alternatives to suit your needs.

Core Temp is a compact alternative that takes away the hassle you’d normally find when running a PC health monitor. It can display the individual temperature of each computer core.

HWMonitor is a hardware-observing software that reads your PC’s main health sensors. This includes voltage, temperature, and fan speed.

MSI Afterburner is an overclocking utility for your graphics card that gives you full control over your GPU.

Fan Xpert is another great alternative fan control application that provides complete access to manipulating your fans and viewing your computer’s health stats.

Total control

This application is a comprehensive solution to controlling your fan speed and monitoring the various aspects of your computer’s health. The interface appears intimidating, but through the use of Speedfan tutorials it quickly becomes easy to understand.

The recent change to the app has improved support for the newer CPU and other components to enable the software to run at full power on even the newest of computers.

SpeedFan is a freeware program that monitors voltages, fan speeds and temperatures in computers with hardware monitor chips. SpeedFan can even access S.M. A. R. T. info for those hard disks that support this feature and show hard disk temperatures. SpeedFan supports SCSI disks too. SpeedFan can even change the FSB on some hardware (but this should be considered a bonus feature).

At the lowest level, SpeedFan is a hardware monitor software that can access temperature sensors, but its main feature is that it can change fan speeds (depending on the capabilities of your sensor chip and your hardware) according to the temperatures inside your PC, thus reducing noise and power consumption.
