SpeedFan is a tool design to monitor the health of hardware devices installed in the computer. Nowadays, multiple fans are highly recommended as computer hardware is more demanding and also needs to be cooled off. These fans can work on their own, but sometimes the aid of an application might be required in order to monitor each fan independently and also to receive information about the power usage of each component. There can also be applied different tweaks in order to make the computer more powerful while still keeping a low resource usage.

The program features a simple installation and the interface is also clean, sharing the same elements that are present in the standard OS interface. An almost instant system scan will be performed and afterwards, the user will be able to see the temperature of the CPU, for example. However, the temperature indicator also features a small icon that informs the user if the temperature is normal or if it is too high. There are a few bonus features that can be used in order to improve the performance and they are bonuses along the classic elements of the tool.

The FSB can be changed with the aid of this application, but only certain hardware is compatible. Depending on the capabilities of the hardware, speed fans can be controlled in order to work faster or slower. This process can be done automatically, as the toll can make changes depending on the average recorded temperature. However, more advanced users that might want to tweak their systems further can manually adjust the speed of each fan. Multiple profiles can be created and saved in order to allow the user to quickly change the fan speeds if he detects a temperature that is too high, for example, when the PC has been used for a prolonged period of time.
