SpeedFan harnesses the info from hardware monitor chips to display in a nicely organized interface all the data one needs to perform overclocking or periodic cleaning of the hardware’s hot parts. Voltages, fan speeds and temperatures of the CPU and GPU are detected in a fast way and displayed on the screen. Access to S.M.A.R.T. info enables it to also gather data on hard disk temperature. On the latest hardware sets, the program is able to change the speed of the spinning fans so that noise gets reduced to an acceptable level.
On certain models, FSB settings can be accessed and modified as desired.
