Have you already encountered situations when your PC hangs when under heavy load or after some hours of usage? SpeedFan is a free tool allowing you to control the voltage, speed and temperature of your PC processor. Thanks to S.M.A.R.T. or SCSI attributes, it can also change the speed of the internal fans according to the temperature of the system, reducing the noise of the computer.

What are the key features of SpeedFan?

SpeedFan displays and controls voltages, fan speeds and temperatures of your PC's processor, thus reduces noise.
The program 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 thanks to S.M.A.R.T. (Self-Monitoring Analysis and Reporting Technology).
