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 4.39 has added full support for Fintek F71889F, even at unusual addresses. Added support for a new method to access SMART data.

Version: SpeedFan 4.39
"Essential tool not only for overclockers"
Pros: + shows the chosen temp directly in the tray
+ shows the CPU usage
+ shows the SMART data, which comes in handy when you want to quickly diagnose your HDD
+ nice configuration options (especially for the tray icon)Cons: - 1.8MB is stil quite a lot for sth that should be just a simple tool
- it used to show wrong readouts on my old A-XP PC. No probs on my C2D laptop though.
- at first it's hard to find the option to chose the readout to be displayed in the tray iconSummary: Essential for overclockers, but also useful for laptops (especially ultra-portables), to monitor the temp when you keep it on your lap or in bed and are likely to block the fan exhaust by accident (burned the CPU fan in my laptop because of that onc... read more >>
