SpeedFan is the popular utility meant for accurately monitoring the status of your computer’s hardware devices. Besides helping you keep a close eye on the parameters of your hardware components, this powerful and feature-rich program also lets you change your computer's fan speeds.

One of the main advantages of SpeedFan is its comprehensiveness.

It also comes with many handy additional features and functions, such as the possibility to set specific warnings and actions to be triggered when certain monitored parameters reach a specific value. For example, it can display a popup message, play a sound, or execute a certain app when the temperature of your GPU reaches a certain value.
