Several sensors, like Winbond's and the AS99127F support fan speed changing, as well as others from Maxim, Myson, Analog Devices, National Semiconductor and ITE, but the hardware manufacturer must have connected the relevant pins to some additional, yet trivial, circuitry. It works on Windows 64-bit versions, too. SpeedFan works with Windows 9x, ME, NT, 2000, 2003, XP, Vista, Windows 7, 2008, Windows 8, Windows 10 and Windows Server 2012. SpeedFan can change the FSB on some hardware (but this should be considered a bonus feature). info for hard disks that support it and show hard disk temperatures, too, when supported. By properly configuring SpeedFan, you can let it change fan speeds based on system temperatures.



SpeedFan monitor temperatures from several sources. SpeedFan is a hardware monitor software that can access temperature sensors, but its main feature is that it can control 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.
