CNET Editors' review
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.
What's new in this version: Version 4.44 has added advanced fan control including a graphical UI for configuration.

"Handy tool for finding out PC temperatures."
Version: SpeedFan 4.44
Pros
FREE! How hot is your rig?
Cons
Not always clear on what temp is which.
-
"Very powerful system tool."
Version: SpeedFan 4.44
Pros
Seems to do exactly what it claims to.
Cons
Not for the faint hearted. If you don't understand the output then don't tinker.
Summary
Downloaded to help with a problem on friend's PC. Did the job admirably.

"Malware Included"
Version: SpeedFan 4.44
Pros
The basic program works as mentioned in previous comments.
Cons
The "StartNow Toolbar" was installed, hijacking homepages in both Firefox and IE9. This occurred on two different computers after installation, both from THIS site! CNET, fix this or remove it from your site!
Summary
See bad-bytes.blogspot.com/2011/08/little-analysis-on-that-zugo-toolbar.html for more info.

"Really Works"
Version: SpeedFan 4.44

App does interact with fan and seems to keep my old system on the safe side of some hot temperatures
Cons

Summary
Small app makes significant difference
-
"Very good, very simple"
Version: SpeedFan 4.44
Pros
Its great always knowing my CPU temp. Good for most computers, but great on Dell laptops.
Cons
Its not the most user friendly interface and many functions are not available for all computers.
Summary
A good, simple program that is great for Del laptops, but only good for other systems.

"gives false info"
Version: SpeedFan 4.44
Pros
looks good
Cons
well it does a poor job if at all of adjusting speed of any fan in mother board, tried with 33 different mb, i am a student and have acess to tons of pc's only 8 adjusted fan speed and only 6 gave correct speed of fan or fans
Summary
this must have been written for a specific purpose and then mass assembeled to fit everyone. i do not see any advantage to this at all, if you depend on accuracy core temp fopr the side bar is far more accurate and if you need fan controll dont be cheap, go cet a actual fan controll that sits in a bay, if you really need fan speed at all.
as for gpu controll the nvidia controll panel blows this away and i am sure ati has a similar platform. good luck dont burn em up -
"Excellent temperature monitoring tool for your computer"
Version: SpeedFan 4.44
Pros
VERY in-depth listing of temperature and system-status info.
Very capable program overall.
Recognizes an amazing number of motherboard or peripheral temperature monitors, even Hard Disk SMART data.
Incredibly useful for the price (free)!Cons
Not the most user-friendly; menuing is sparse and very streamlined.
Summary
It's a very capable tool...but it is a bit less user-friendly than it could be. It's incredibly good for a free tool, and it recognizes an amazing number of motherboard, video and hard disk temperature monitoring sensors, it's just not as 'polished' as it could be for the Average Joe. It's a wonderful tool for power users and technicians; I've considered it indispensable for years now.
