SpeedFan 4.52
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.
SpeedFan monitor temperatures from several sources. By properly configuring SpeedFan, you can let it change fan speeds based on system temperatures. SpeedFan can also access S.M.A.R.T. info for hard disks that support it and show hard disk temperatures, too, when supported. SpeedFan can change the FSB on some hardware (but this should be considered a bonus feature).
SpeedFan works with Windows 9x, ME, NT, 2000, 2003, XP, Vista, Windows 7, 2008, Windows 8, Windows 10 and Windows Server 2012. It works on Windows 64-bit versions, too.
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. From one of the very first hardware monitor chips that could be found in standard PCs, the National Semiconductor LM75 (and all of its clones, like the Philips NE1617 and the Philips NE1618 or the Maxim MAX1617) or the Analog Devices ADM1021, such chips have been greatly improved, both in their precision and in their capabilities.
