CNET editors' review

Reviewed by: CNET Staff

This free program offers some useful system details to those savvy enough to understand its results. SpeedFan's tabbed interface isn't hard to navigate, but most users won't be able to make head or tail of the data this utility provides. The program's system-tray icon tells you the temperature of your PC's hard drive, and you can receive information on voltage and fan speeds.

The utility can display SMART data and includes a tool for resetting motherboard clocks. Basically, if this review makes no sense to you, SpeedFan is above your head and won't be worth downloading. However, PC technicians and those who like to do their own system maintenance might as well take a look at this application, particularly since it costs nothing.

Publisher's description

From Almico Software :

SpeedFan monitors voltages, fan speeds, and temperatures in computers with hardware monitor chips. It can even access SMART information for hard disks that support this feature, and show hard-disk temperatures if that's supported. SpeedFan fully supports SCSI disks and can even change the FSB on some hardware (but this should be considered a bonus feature). At the lowest level, SpeedFan is a hardware monitor software that can access temperature sensors, but mainly it can control fan speeds (depending on the capabilities of your sensor chip and your hardware) according to the temperatures inside your PC, thus reducing noise and power consumption.

Version 4.31 may include unspecified updates, enhancements, or bug fixes.
