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.

"Works great if you know what you are doing"

September 05, 2012  |  By inaun

 |  Version: SpeedFan 4.46

Pros

Monitors temp and automatically controls fan speed based on current temp. Slowing fans when appropriate allows system to run with less noise.

Cons

Windows 7 security! SpeedFan will not automatically start because you have to answer the "do you want to allow this program to make changes" security prompt...unless you turn this security feature totally off. Thanks so much M$ for protecting us against programs we want while leaving gaping holes for the malware we don't want.

Summary

As CNET review says, you do need to know what you are doing to use this utility. It is most useful for people who have built their own computer, so know which fans can be safely modified -- or for overclockers who need to closely monitor temperatures (and again, have a higher level of tech-savvy than most users.)

That is not to scare anybody away. If you are willing to read the help files and invest a bit of brain power to learning, you will gain a better understanding to the internals of your system.

As a tech person, I find this program very easy to configure and use. You can change labels (e.g. instead of "Fan1" change to "Back Case Fan". Fans can be independently controlled based on specific temperature sensors (e.g. mid case and rear fans could be adjusted based on hard drive temp), CPU fan controlled by CPU temp, etc.). Even has charts to analyze swings.

For people interested in more than fan control / temp monitoring, this utility also throws in some other features like clock control and voltage monitoring.

Obviously hardware is a factor as it would be for any low-level utility like this. Both from a compatibiliy and a hardware feature perspective. For example, the guy who says it has "unbelievable temperatures" obviously has underlying hardware issues since temps are simple reads by SpeedFan of what the hardware devices claim the temperature to be.

"Used on 3 PCs, very inaccurate, unreliable"

May 18, 2012

 |  Version: SpeedFan 4.46

Pros

Its a simple program that sits in the taskbar and shows an average read of the PC's Temperature

Cons

The results are unbelievable. Right now one PC says -17F, 1 says 109f, and one says 89f. All in the same room, all un tasked.

Summary

Useless to me. FYI: I am using it on a Dell, AsRock, and an ASUS motherboard
