SpeedFan is a hardware monitoring program that allows you to find out the temperature and voltage of your PC components, as well as the revolutions at which all the fans are spinning. Depending on the type of fan you have connected, you may be able to modify its speed.
Temperatures and speeds on the same screen
When you open SpeedFan, the first thing you will see is the readings screen, where you can see the CPU usage in real-time, the revolutions at which the fans are spinning, and the temperatures of your PC's components, including CPU, GPU, motherboard and hard drives, and SSD drives.
At the bottom, you can see your PC components' real-time voltages and the percentage at which the system fans are spinning. You will only be able to control the speed of PWM-compatible fans, i.e., those with a four-pin connector and connected to one of these connectors on the motherboard. As a result, you will be able to see how the fan speed affects the components' temperature and the noise they can make.
Check the temperature of your components in the taskbar
With SpeedFan, you can also control some motherboard and chipset settings, as well as create a screen displaying all the data of the components you decide to focus on. From SMART, you can also view the status of your storage drives, and in the graph section, you will see the temperature evolution in recent seconds and minutes.
Another interesting feature of SpeedFan is that you can display the component's temperature in the taskbar, so you don't have to open the program to see it.
Download SpeedFan and control your PC's fans while monitoring component temperatures.

Unfortunately, it can no longer be integrated into autostart. Otherwise, good product.
This app is good for cooling the PC, but it has an annoying bug that every time I turn off the PC and turn it back on, the option to increase speed disappears, so I have to go to the settings, activat...See more
Hello. If worth, 4 stars
It's super good, I can see if my PC is in good condition. It's great, I loved it.
Hello, I'm having issues with the fan as it only measures the RPM of fan1. The next two fans, fan2 and fan3, show zero and don't register any readings. What could be the problem? Thank you in advance.
I have issues with the microprocessor; it heats up and shuts down. Does this program solve the problem?
