SpeedFan monitors fan speeds, temperatures and voltages in computers with hardware monitor chips. It can even access S.M.A.R.T. info for those hard disks that support this feature and show hard disk temperatures too, if supported. It can even change the FSB on some hardware. At the lowest level, it is a hardware monitor software, but its main feature is that it can control fan speeds according to the temperatures inside your pc, thus reducing noise and power consumption.

    Made my fans fun so fast it sucked the cat into the PC case, I never noticed they were running fast though.

    Good, interface a bit dated but it's free & does the job well.

    A classic piece of freeware. Yea, the interface is what it is. However, it is probably best kept complex to prevent accidental misconfiguration by the layman. A little intimidation on advanced projects is sometimes appropriate. The author also has a minimalist design to his web sites, except for the ads, which are a little aggressive. He might tone them down, but that's the site. Software is good.

    This %&¤&%¤% destroyed one tiny fan on my mobo ! If i knew that all fans where set to 100% when Windows were shut down i had prevented this disaster. It was a while ago, but i warn people from using this without going throuth all settings properly, twice !!!!

    Nope, it was NOT my fault the setting were 100% after install and the 1st start. I can only blame the program. I usually always check settings properly in software i install. I didn't with this one. That fan it destroyed should never have a speed above 25%. To You below who blame me, got to H !
