SpeedFan – Main Features

At first glance the program was very light, taking up just 5.0 MBs of RAM and next to none from the computer’s CPU:

When we installed the program and by the way that was lightning fast, we noticed that it detected and attached itself directly to the sensors of the laptop it was working on. Then we noticed which sensor was for which indicator:

Then we went deeper, into seeing the features for advanced users. The results were very satisfying. The program allowed several interesting overviews of the temperature of the GPU, CPU cores, HDD and Temp1 and it even had the ability to present one chart to compare whichever you would like to compare. This is perfect in case you are doing a comparison test between two devices:

In addition to that, the program favors the users interested In HDD’s as well. It allows users to perform even a so-called “S.M.A.R.T.” check of their hard drive and display hard drive errors as well as its temperature:

This program is very suitable if you want to change your fan speed in case your fan Is partially broken or noisy especially at high speed. In addition to that the program can even tamper with and work with the sensors of older devices, 64 bit and older versions of Windows:

  • 9x
  • ME
  • NT
  • 2000
  • 2003
  • XP
  • Vista

The program can cope with nearly any values of the:

  • Hardware chips.
  • Temperatures.
  • Hard drives.
  • Fan speed results.
  • PWMs.
  • South Bridges.

The simplicity and the size of the program with those features are perfect not only for tests but for active usage in case you want to watch constantly over your device’s temperature. Finally, we have to say a good word for the advanced settings which allowed us to modify and change different preferences according to our demands:

What We Like

We enjoyed several different aspects of this program:

  • Lightness.(5.77 MB in size)
  • Simple design.
  • Non-performance demanding.
  • Fan control feature.
  • Focus on the HDD speed and temperature.
  • New “Magic” features about to be added in the future version.
  • Clocking feature.
  • GPU fan speed and monitoring.

What Is Missing

It was very difficult to find something that needs improving in this software:

  • A bit more modernistic design.
  • The chart can be added to the General tab where as soon as you change the fan speed you can be able to see the difference.

Conclusion

As a bottom line we have to admit that this is probably one of the best software, if not the best out there for temperature measurement and fan modification. It totally blows away any competitive software with its lightness and in the same time features and advanced preferences to tamper with.

Note: This test was performed on a Lenovo B50-70 with 64-bit Windows 10
