FanControl is a hardware monitoring software that can access temperature sensors, but its main feature is that it can control fan speed – depending on the capabilities of your sensor chip and hardware – according to your PC’s internal temperature, thus reducing noise and power consumption.
It monitors temperature from several sources. By configuring it properly, you can allow it to change fan speed based on system temperature. SpeedFan can also access SMART information for hard disks that support it and display hard disk temperatures when supported. It can change the FSB on some hardware (but this should be considered an extra feature).
Some sensors, such as Winbond’s and AS99127F support variable fan speed, as do other sensors from Maxim, Myson, Analog Devices, National Semiconductor, and ITE, but the hardware manufacturer must connect the relevant pins to some additional circuitry, but not significantly. From one of the first hardware display chips that can be found in standard PCs, the National Semiconductor LM75 (and all its knockoffs, like the Philips NE1617 and Philips NE1618 or the Maxim MAX1617) or the Analog Devices ADM1021, the These chips have improved dramatically, both in terms of their accuracy and capabilities.
Current chips can monitor fan speed, voltage, and control fan speed using PWM (Pulse Width Modulation). Some chips can even be programmed to change fan speeds without any additional software intervention. If your BIOS is programmed to set up such chips this way, you can still try using SpeedFan’s Advanced Configuration to revert back to manual (software controlled) mode. Winbond W83697HF, Analog Devices ADT7463, SMSC EMC6D102, ITE IT8712F, National LM85C and Maxim MAX6650 are very good candidates. Some SuperIO chips also include a temperature sensor.
