Editors' Review

+

SpeedFan helps you stay on top of your system's vital statistics, including temperature, fan speed, and others, to ensure that things are running smoothly. Aside from basic monitoring, this program enables users to troubleshoot issues and make adjustments to various systems.

Pros

Clear interface: This app's interface is nicely organized into sections that you can move through using the tabs across the top of the screen. Options here include Readings, which features stats about CPU Usage, Fans, Temperatures, and more, Clocks, which lets you reset your Motherboard clocks, and SMART Data.

Charts section: There is also a section that lets you create charts to visualize data recorded about various aspects of your computer. You can choose to see readouts of Temperatures, Fan Speeds, and Voltages to get a better idea of the way these values are trending over time so you can quickly identify when something is going wrong.

Cons

Not for beginners: Most of the information this program presents will have little meaning to inexperienced users. There are good warnings about taking actions that could potentially harm your computer if you don't know what you're doing, so you're not likely to do any harm. But it won't do you much good either.

Bottom Line

SpeedFan is a nice, free utility to help you monitor various aspects of your system. It presents all data clearly, and you can find what you're looking for quickly, thanks to the conveniently tabbed interface. It's not much use if you don't have some significant knowledge about your computer's inner workings. But for power users, it's a good tool.

"Essential system utility"

November 14, 2014  |  By Fanboy123

 |  Version: SpeedFan 4.50

Pros

-Full control over all the controllable fans on your system.
-System Fan's can be link to any temperature the reading the software can detect. Want to link a system fan blowing on your videocard to the temperature of your video card, no problem. No other software I am aware of, can do this.

Cons

-Can be daunting to for layman users to set-up, but well worth the effort to do so. Even though no official 'manual', there are plenty fo setup guides out there.
-Cnet version seems to have bloat, from the other reviews. Best to get it from author's website for a clean installer.

Summary

First, don't know what reports about trojan's, etc is. If in doubt, take the time to download from the author's website as the installer on the latest version, I just tried, has nothing like that. It will install a service for the program to monitor all it needs to monitor, that's it.

To the program itself. The review on this website is not helpful. Most sites classify this as a monitoring product, which make it no different to lots of other software you can get to monitor temperatures, fans speeds, voltages etc. Those reviews and classifications miss the point though.

This is a unique piece of software. Where as other software tells you your temperatures, fan speeds etc, what this software does with those details is unique, and makes it the first piece of software I install on my a new system after OS patches and drivers.

This software allows you to control all the fans on your system (if you have a compatible fan controller) and link those fans to any of the temperatures it is monitoring. Not only one temperature though, per fan, but many. You can then create graphs of how your fans should speed up or down depending on those temperatures.

Some motherboards support fan speed up when temperatures on the motherboard (from the temperature readings of mother board sensors), start to get high. They do not support the motherboard controlled fan speed up to be determined by temperatures of temperature sensors external to the motherboard, like videocards and hard drives, etc. This software is the only one that does.

This only works with compatible fan controllers and the software author Alfredo is always working to include the latest hardware. Though if anyone has got some programming skills, I think he could do with any help to keep this software up to date. Also donations I believe will help, with getting more resources to allow more controllers and sensors to be incorporated.

Before you ask I have no involvement with the software and am solely a user of it. I did request that a graph system to match the temperatures to fan speeds be implemented via a posting on the authors website and it was....

Anyway if you like to have your PC quite when not in much use and cool when gaming, this is a vital and unique piece of software to have installed, to give you full control over your cooling.

There is no official setup guide, but there are multiple user created guides out there. Some examples are:

http://www.youtube.com/watch?v=xUkmXCSUbHE

Many others can be found with a quick goggle search.

Cannot recommend this program enough if you build your own systems and want full cooling control.

"Its GREAT ! ! ! ! !"

November 09, 2014  |  By FredMcD

 |  Version: SpeedFan 4.50

Pros

My computer, of late, had several times died. It did not shut down or power down,
it just died. I had noticed, of late, that the area around the touch pad was VERY hot.
I looked for a utility to show me what was going on, and tried SpeedFan, When I
run it, it showed that everything was on fire. A trip to the tech, and it's much better now.

Cons

Would like better instructions, display

"Good program"

October 07, 2014  |  By ajpctech

 |  Version: SpeedFan 4.50

Pros

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

Cons

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

Pros

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.

Cons

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

August 14, 2014  |  By wiegerw

 |  Version: SpeedFan 4.49

Pros

Don't download this! The installer from the official site appears to work.

Cons

It installs malware on your PC. Until now I trusted CNET, that turned out to be a big mistake.

I will not use CNET again.

"Speedfan bundled with malware!"

June 18, 2014  |  By lsharpe69

 |  Version: SpeedFan 4.49

Pros

Software works good so far as I can tell, but once you download from CNet and run Speedfan the malicious payload has already installed.

Cons

This malware bundle gives you option to 'decline' each payload installation, yet even if you carefully decline all baggage it installs anyway. Visible in control panel (Windows 7 Ultimate) but will NOT uninstall. Had to run Malwarebytes in safe mode w/networking to quarantine the 300 items found. CNet denies this is an issue and deleted my original post. I simply asked them to go home and install on own PC from their own site! Even after quarantine your Google spellll check will no longer function either (unless you manually correct). I need to replace my hard drive anyway, so this nightmare will go away. Yet your 'Elm Street' will begin here!

Summary

DO NOT INSTALL THIS SOFTWARE FROM CNET. It is loaded with malware and CNet is in denial. Don't say you weren't warned. If you are a novice user? Avoid completely. I will no longer believe CNet is a secure source for software. This is proof in the pudding!

"Could be a good tool, but didn't work with my computer."

April 29, 2014  |  By jandsm5321

 |  Version: SpeedFan 4.49

Pros

Simple, light, lots if information on your computer.

Cons

The numbers it reported weren't accurate, Even going to the BIOS showed different numbers than what SpeedFan was reporting so I'm not sure where they got theirs.

Summary

I don't know where people get this idea of malware. I suspect the error is between their chair and the keyboard. First, CNet has been adding ads when you use their auto-downloader. Second, CNet has adds that mimic download links that usually send you to shifty websites. I didn't see any malware, it didn't change any settings on my computer.
