SpeedFan Description:
SpeedFan is a freeware program that monitors fan speeds, temperatures and voltages in computers with hardware monitoring chips. SpeedFan can even access S.M.A.R.T. info for those hards disks that support this feature (almost all :-)) and show hard disk temperatures too, if supported. SpeedFan can even change the FSB on some motherboards. At the lowest level, SpeedFan is an hardware monitoring software, but its main feature is that it can control the speed of the fans (depending on your sensor chip) according to the temperatures inside your pc, thus reducing noise and power consumption. Most Winbond sensors and ASUS AS99127F support fan speed changing, as well as others from MYSON, ANALOG DEVICES, NATIONAL SEMICONDUCTORS and ITE, but the motherboard should make use of available pins. This means that if you have, say, a W83782D on a BP6 then you're ok. If you have a W83782D on some GigaByte's... you're not :-)
Note: This program is aimed to the power user. To the one who knows what he's doing.
Operating System Support: Win9x, WinME, WinNT, Win2k and WinXP
Review for SpeedFan
Is voltage information accurate?
Has someone tried monitoring the Voltage readings? I find that the -5V and -12V readings are not where it has to be. Is this a problem with the tool or is it a problem with the power supply itself?
THE VERY BEST OF ALL THE CATEGORY AND FREE
I'VE ALWAYS USED IT AND NEVER FAILS TO ACCOMPLISH IT'S TASKS FOR HD HEALTH AND PERFORMANCE.
I installed this on my Toshiba laptop with a centrino cpu. Promptly locked up the machine, and required a re-boot.
