3-Step Guide to Using SpeedFan to Control Your CPU Fan Speed Like a Pro

If you’ll be using SpeedFan to control how the speed of your CPU fan operates, you have to be very careful and deliberate with your actions.

With this in mind, here’s what you need to know to use this program properly from start to finish.

Step One – Download and Install the Software

As you can’t do anything without having the application on your PC, the very first step becomes finding, downloading, and installing SpeedFan on your computer. To get the safest and most recent version of this software, ensure that you go directly to the official website of the app.

Once you’ve downloaded and installed it, allow the program to run. It’ll promptly scan your device and, once it’s done, it’ll highlight all relevant information about your PC in the main window.

Some data you can expect to glean from here include your fan RPMs as well as the temperatures of your motherboard chipset, graphics card, and CPU, to mention a few.

This is the most ideal point to start to intimate yourself with the various labels on display as well as what they stand for. Knowing this will help you put the app to better use. Remember, if you don’t know what the settings do, do not toy with them. Doing otherwise can damage your system.

Step Two – Tweak the Fan Controls

While SpeedFan can be somewhat challenging to use, the program also makes using it a bit simple in some aspects. As an example, it offers users the “Automatic Fan Speed” function. With this feature, you essentially give SpeedFan free rein over the fan settings of your CPU. In most cases, it’ll use this to adjust the speed of the fan following the estimated cooling needs of your PC.

However, this quick fix doesn’t produce perfect results in all scenarios. This means that you may need to move things around in the fan speed settings area to get just what you want.

You can start by clicking on the “Configure” option. You’ll be presented with a list of functions. Click “Chip” next. This will bring a dropdown menu where you can find and select your motherboard chipset.

Once here, you can try setting all the PWM Mode choices to “Manual” and see what kind of result you get from that.

Step Three – Configure the Automatic Fan Control Setting

Once again, you’ll have to click on the “Configure” option. Next, go to “Speeds”. Here, you’ll be able to manually set the minimum and maximum RPM you want for your fans. Typically, the major factor that should influence the numbers you set here is how heavy the programs you run on your device are.

After you’ve gotten the hang of that, find your way to the “Fan Control” tab. Once here, you should create what you think is the optimum temperature curve for the fan of your CPU. This step is essential as it’s what’ll let you see if the adjustments you’ve made up to that point have had the desired influence on your device.

You should also check the “Temperatures” tab as well and use it to speed up or slow down your fan speed. You can use how hot your PC gets to inform your decision here. Along these lines, be sure to choose what sensor you want to monitor and regulate the fan of your CPU as well.

Keep in mind that you’re supposed to save all the changes you make to the settings as you go along. That’s the only way that they’ll take effect.
