A PC fan controller is a device that connects to your PC's fans and modifies the speed at which they spin. Most PC fan controllers have multiple settings that allow you to control the speed of each individual fan. This can be useful when you want to run your computer at maximum fan speed to cool it down, but don't want it to overheat.

What is a Fan Controller Used for?

A PC fan controller makes it easier to keep track of temperatures. Most of them come with software that allows you to adjust the PC fan speed manually. It also helps you maintain the ideal blend of cool and silence for your system. All electronic equipment benefits from a speed controller. It conserves energy, minimizes noise, and extends the life of the equipment. A PC fan controller allows you to swiftly modify the speed of your fans.

Why is a PC Fan Controller Necessary?


A PC fan controller assists in the automatic cooling of your system. It comes with a ten-port hub, a PWM signal cable, and various bolts. This attaches to your motherboard for quick setup. Connect the 4-pin fans to SATA power to achieve high-performance cooling.

Better Performance

The majority of fan controller displays are simple. They show basic information such as temperature and revolutions per minute (RPM). The PC fan controller consists of software for better performance. It allows you to change them using a program. The PC fan controller is a long-lasting and simple way to connect to the system.

Safety and Monitoring Features

A PC fan controller controls between four and six case fans. It is simple to install and fits into the vast majority of PC cases. The fan controller also has a screen that displays the current fan speed. You can control it both manually and automatically.

How to Monitor Fan Controller Speed?

Your computer may overheat when it is working long hours. Keeping the PC temperature down is possible with a fan controller. Use the software or inspect the components to gain insight. You can also check the PC's fan speed to ensure it's functioning properly.

Check Computer Fan Speed

The PC fan in your computer removes the heat from the processor and keeps it cool. This helps in preventing your computer from overheating. When the components of a PC overheat, there will be a drop in performance. Your computer should also include a fan to keep the inside of the casing cool.

Conduct a Physical Inspection

One of the simplest ways to check computer fan speed is to look inside the case. This is only applicable when you have easy access to it. Some PC fans are connected to a heat sink. It is then connected to the motherboard. The others have a built-in heat sink and both connect to the motherboard.

Check Your Fan in BIOS

You might find it quicker to use the software to check the fan speed. The essential information you'll need to determine the performance is there in the BIOS of your computer. The controls you have in BIOS will vary depending on the machine.

Check Your Fan Using Software

 You might find it easier to utilize a third-party fan speed controller to monitor and modify your fan speed. The ideal tool will be unique to the equipment you have. Check whether your PC's CPU maker provides software specific to the type of CPU you're cooling.
