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 is a freeware program that monitors voltages, fan speeds and temperatures in computers with hardware monitor chips. SpeedFan 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. SpeedFan can even change the FSB on some hardware (but this should be considered a bonus feature). At the lowest level, SpeedFan is an hardware monitor software that can access temperature sensors, but its main feature is that 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: SpeedFan 4.20
Pros: FSB feature is awesome. You can adjust FSB with ease 1 MHZ at a time on most modern mobos! Monitors fans, voltage and temperature. Even slows down the fans for quieter operation.
Cons: Learning curve but worth it. BEWARE if you are new or inexperienced with the overclocking features!

Version: SpeedFan 4.20
Pros: SpeedFan does everything the authors claim extremely well in one neat little FREE package. It?s been monitoring the temperature on my two Win2k Pro computers without any problems for almost two years. No bloat, no spyware, not a resource hog at all. SpeedFan is also one of the best and easiest to use software tools for overclocking your FSB and memory. It works well for experimenting with settings before hardware overclocking, or for motherboards like mine that don?t support hardware overclocking.
Cons: No cons really. Make sure you know what the acceptable temperature ranges are for your system and set them appropriately. SpeedFan will help protect your system and warn you if it overheats, but only if you set it up correctly.

Version: SpeedFan 4.20
Pros: Free, Installed fine.
Cons: First attempt to run the program immidiatly froze my computer after it had displayed a part of the SpeedFan window, even my cpu fan stopped. Had to force reboot. Tried once more and exactly same thing happened.
I run updated XP Pro on a Dell C640 Laptop (2.0 P4-M) which otherwise has no problems.
