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.

"Good program"

October 07, 2014  |  By ajpctech

Helps to know all your fans' speed to see if they are over working and getting too hot especially when overclocking.


It could load malware if not careful and decline all the optional requests. It's better to get it from filehippo.com

"Resolved my overheating problem, no malware found."

August 19, 2014  |  By greenLibertarian

 |  Version: SpeedFan 4.50


This program helped me identify the reason my computer was overheating: the fan speed was not increasing as temperatures increased.
The monitoring is very useful. I have not tried the advanced features, no need.

I scanned my computer with multiple malware/spyware programs after reading some of the reviews, and found none.


Would prefer to pay after trial period to the several revenue install options.
