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.
What's new in this version:
Version 4.40 has improved identification of Winbond W83667HG and added support for ADP3228 fan reading.

Version: SpeedFan 4.40
"Poor User Interface, Poor Documentation"
Pros: It's free.
Cons: SpeedFan has promise, but certainly isn't there yet. The user interface is confusing and poorly documented through the help file.
Summary: Seems kind of strange, but if I interpret the little help text that's available, my Core 2 Duo PC's hard disk is running at 84 degrees centigrade (or -69 degrees centigrade, hard to tell). If it's truly running at -69 degrees, my PC is the best free... read more >>

Version: SpeedFan 4.40
"Light, accurate, integrable voltage/temperature monitor"
Pros: uses very small amount of resources
it is integrable with ALL CPU METER gadget for vista/7
provides separate core tempsCons: for obvious reasons, the auto/manual control of fans in many systems does not work as easily as checking an option.
for a program of its size, & for a program that uses such little amount of resources, it does take quite a few seconds to fully load.Summary: Use it, add it to your start up, and best take advantage of it by using it on your sidebar gadgets.
This is one HIGHLY NEEDED software for hardcore gamers and overclockers who need to keep a constant eye on component temperature and perfo... read more >> -
Version: SpeedFan 4.40
Pros: Keeps temps in check.
Cons: None that I can see.
Summary: I'm no techno-geek and I have an older xp laptop so the it can't control the sensors and fan speeds. Its cool to see my internal temps and recognize the vulnerable areas that I need to pay attention to.
