The first thing you want to do is see if your motherboard is compatible with Speedfan’s fan control feature. If your motherboard is not supported, you can still use SpeedFan to monitor or debug the program.
If your motherboard is supported, go to your system BIOS and disable automatic fan controls. This will prevent a conflict between SpeedFan and the system fan settings. Once you’ve done all that, install and launch SpeedFan and allow it a few seconds to scan for the sensors on your computer. Once completed, you will be greeted with a range of temperature readings for different components like CPU, GPU, and hard drive.
Next, you will want to click the “Configure” button on the right side. Navigate to the “Options” tab and make sure “Set fans to 100% when exiting the program” and set “Delta value for fan speed” to 99 (maximum). This will ensure that your fans won’t stay on the presets, even if your temps skyrocket.
Now go to the “Advanced” tab to select your motherboard’s superIO chip from the drop-down menu. Look for the PWM modes that need to be changed for manual PWM control. You can then change the fan speed percentage with the up and down arrows or enter a menu value. If you set the rate lower than 30%, there’s a chance that the fan RPM will read incorrectly, so keep this in mind.
Next, you will want to set up automatic fan control by going to the “Speeds” tab. Here you will find the minimum and maximum values for each fan of your ingredient. Make sure to check the box for “Automatically variated.”
Navigate to the “Temperatures” tab, where you can expand specific components and set the temps where you want them to run and when to give you warnings.
You might want to experiment with some fan speeds if they’re too loud or if your parts aren’t cooling fast enough. You can also select “Show in tray” to display which items you want to monitor. Finally, don’t forget to add a shortcut to SpeedFan to the Start-Up folder so that it launches on startup.
Now you are in complete control of your cooler!
