SpeedFan is a program that monitors voltages, fan speeds and temperatures in computers with hardware monitor chips. SpeedFan can even access S.M.A.R.T. info and show hard disk temperatures. SpeedFan supports SCSI disks too. SpeedFan can even change the FSB on some hardware.
SpeedFan lets you take a deeper view at the status of your computer. Almost every computer includes support for hardware monitoring. Accessing digital temperature sensors is really useful. If you are trying to figure out why your PC hangs when under heavy load or after some hours of usage, SpeedFan might help you find the real cause.
SpeedFan can access status info from EIDE, SATA and even SCSI drives, consistently showing internal data that can be used to diagnose current and future hard disk failures.
At the lowest level, the SpeedFan hardware monitor software can access digital temperature sensors, but its main feature is its ability to control fan speeds according to the temperatures inside your PC, thus reducing noise.
SpeedFan can handle:
- Almost any number of South Bridges
- Almost any number of hardware monitor chips
- Almost any number of hard disks
- Almost any number of temperature readings
- Almost any number of voltage readings
- Almost any number of fan speed readings
- Almost any number of PWMs
