Introduction
When it comes to keeping your system cool, case fans play a crucial role.
These fans help to dissipate heat and maintain optimal operating temperatures for your hardware components.
Changing the voltage of a case fan can be useful for various reasons.
Therefore, its essential to proceed with caution and understand the risks involved.
Keep in mind that the availability of options may vary depending on your specific hardware configuration and BIOS parameters.
With that said, lets dive into the process of changing your case fans voltage on Ubuntu.
Most case fans typically operate at either 12 volts (V) or 5 volts (V).
The multimeter will display the voltage reading, which will help you identify the voltage requirement of your fan.
To begin, you could refer to your motherboards user manual.
Look for any sections or chapters that discuss fan control or voltage tweaks.
Another option is to visit the manufacturers website and search for your motherboards model.
Look for any documentation or FAQs that mention voltage control or fan configs.
The BIOS is a firmware interface that allows you to configure various aspects of your computers hardware.
Within this section, you should find options related to fan control or voltage.
The specific location and wording of these options can differ depending on your motherboard model and BIOS version.
Look for terms such as Fan Control, Fan options, or Hardware Monitoring.
Keep in mind that changing the voltage in the BIOS affects the fan speed directly.
after you snag made the desired changes, save the tweaks and exit the BIOS setup.
your setup will reboot, and the new fan voltage tweaks will take effect.
One popular software tool for fan control is lm-sensors.
Its recommended to choose the default options by pressing Enter for most of the questions.
Once the detection is complete, the command will generate a configuration file for lm-sensors.
Take note of the sensor names related to your case fan.
To modify the fan voltage, you’re free to use the pwmconfig command.
However, this command requires superuser privileges.
In such cases, you’re free to explore alternative software options like fancon or fancontrol.
Simply launch the utility, locate the fan parameters, and make the desired changes.
Typically, you will need to connect the fans to the controller using their respective power and control cables.
In this article, we discussed five steps to change the voltage of your case fans.
Making voltage adjustments beyond the recommended range can potentially cause damage to your components.
