SpeedFan is a program that monitors voltages, fan speeds and temperatures in computers with hardware monitor chips. The application can be run as a Windows Service using FireDaemon Pro, which lets you have the application start automatically at boot prior to login, start multiple instances of the application and more. This HOWTO will show you how to set it up. You can also use FireDaemon Fusion to manage FireDaemon and other Windows services via a web browser.

SpeedFan Setup Under FireDaemon Pro

Download the latest SpeedFan files from the SpeedFan website here.

Install the SpeedFan application. By default it installs to C:\Program Files (x86)\SpeedFan.

Run the application at least once to change any settings.

Download and install FireDaemon Pro into the directory of your choice, typically C:\Program Files\FireDaemon.

Next start the FireDaemon GUI from the desktop shortcut. Click on the "Create a new service definition" button in the toolbar (or type Ctrl+N) and enter the information into the fields as you see below. Adjust the paths to suit your installation. Note that no parameters are required.

  • Executable: The path to your speedfan.exe file. For the purposes of this HOWTO, the path is C:\Program Files (x86)\SpeedFan\speedfan.exe.
  • Working Directory: The directory containing your speedfan.exe file. For the purposes of this HOWTO, the path is C:\Program Files (x86)\SpeedFan.
  • Parameters: None. Leave this field blank.

Now click on the Settings tab. If you DON'T want to see SpeedFan running, uncheck the Interact with Desktop check box & select "Hidden" from the "Show Window" dropdown. You must run SpeedFan as the user you installed it as. In the Logon Account field type your username (e.g. Administrator) and then enter the user's password twice in the Password and Confirm fields. You can change the Process Priority to allocate more CPU time to SpeedFan or specify which CPU or core SpeedFan will run on (in the case of multi-processor, hyperthreaded or multi-core CPUs).

Now click on the Lifecycle tab. Uncheck Graceful Shutdown as it can slow the shutdown of SpeedFan.

Now click on the Install button to install and start SpeedFan!
