This post/Thread is in response to another post, that deals with PC overheating issues and such.

SpeedFan is a FREE Windows utility 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 and show hard disk temperatures too, if supported.

At the lowest level, SpeedFan is a 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.

If you need a tool that can change your computer's fan speeds, read the temperatures of your motherboard and your hard disk, read voltages and fan speeds and check the status of your hard disk using S.M.A.R.T. or SCSI attributes, then this is the utility for you.

It is fully configurable and you can create custom events to handle every situation in an automated way.

SpeedFan works under Windows 9x, ME, NT, 2000, 2003, XP and Vista. SpeedFan works fine on Vista 64 bit too. The relevant driver is fully digitally signed. And this all costs you absolutely nothing!


SpeedFan has been fully tested and currently used by City Computer Service as a diagnistic tool .
