You will be able to know the temperature of the micro, HD, fan speed and charge of the CPU. Now you can sleep without having to worry.
And that is not the main function of Speedfan, because it offers you the information and... it allows you to control the speed of the fan to avoid unnecessary sound or speed it up to cold your computer.
It is very easy to use because it detects automatically all the information, you don’t have to do nothing. Just run it and you’ll have all the information you need.
And if you minimize it, you’ll see the most important info on your system tray.
