This works best for 4-pin fans, and with this you can control up to 8 of them. While this will also work with 3-pin fans, you just get these particular fans working at maximum speed.

But with the 4-pin fans, you get accurate speed detection and speed control for the fans.

Best PC Fan Controller Buying Guide – Things to Consider

How do you know if the fan controller is any good? Which fan controller best suits your needs?

To answer these questions, you have to read the product specs and reviews. While you do so, make sure you pay special attention to the following factors.

Pins

The number of pins determine what kind of features and controls you enjoy with your fan controller. Older models tend to have only a 2-pin design for current flow (positive and negative).

With newer fan controllers, you may be able to handle 3-pin and 4 pin designs. A 3-pin design gives you rpm monitoring capability, while the 4-pin also adds pulse width modulation.

Auto or Manual

This refers to how you can control the fan speed. If you have to do this manually, then that means using the software that comes with the fan controller to adjust the setting for the fan speed.

But some fan controllers also offer auto fan speed setting. That is, the fan controller monitors the temperature and then adjusts the fan speed to compensate. That way, you can continue your PC activities without having to worry about whether it’s getting too hot in the PC.

Display

Many fan controllers come with an LCD display, though others have knobs to let you adjust the settings.

Channels

The channels refer to how many fans you can control with your fan controller. If you have a 4-channel fan controller, that means you’re able to control 4 fans.

Compatibility

Some fan controllers may be designed for a particular type of computer, such as a Mac. Make sure that the fan controller you can is actually compatible with your PC.

Number of ports

These are the ports you use for your 3-pin and 4-pin fans. Again, this determines the number of fans you can control.

Speed Control Options

Just how are you able to control the speed of the fans? What kinds of speeds are available?

Lots of built-in fans for PC tend to run on a minimal speed setting, which isn’t great when you’re working your PC really hard through gaming or video editing. It’s best if you can then compensate by being able to increase the fan speed to match your need to keep your PC healthy.

Monitoring Capabilities

Your fan controller may be able to monitor several factors that you ought to know about, so that you can make sure that your PC is working properly.

Fan controllers may be able to monitor such factors as the temperature inside your PC, the voltages, and also the current speeds of your PC fans.

Other fan controllers may also check the temperatures of specific PC components, such as the CPU, the GPU, and the hard disk. They may also monitor the FPS, the memory usage,

Design

This is about the look or aesthetics of the fan controller. Some owners of gaming PCs like to go with fan controllers just for the look, since they add to the overall “coolness” of the PC.

Noise

One of the reasons why you want fan controllers in the first place is that you may be able to balance the need for cooling the PC with the need to keep things from getting too noisy.

If the fans in your PC are always on maximum rpm, then you can end up with quite a ruckus. That can be annoying, especially when you’re just trying to finish writing something and you need to concentrate.

That’s why you want to be able to control the speed of the fans, so that you can reduce the fan power if the PC isn’t working all that hard.

Benefits of Fan Controllers

When you’re using your PC for rather intensive activities like video editing or playing graphics-heavy games, your CPU and GPU can go bonkers and generate more heat. To keep the temperature down (and minimize the risk of damage to your PC components, you need fans to cool things down.

The problem is that when you add more fans to the PC system, it’s too much of a hassle trying to set up your fans with your motherboard. That is, if that’s even possible.

With the fan controllers, you don’t need the motherboard to control the fans you have on your PC. It’s a much easier setup.

In addition, it also offers increased capabilities for monitoring temperatures (and other factors) and for controlling the fan speed. You’re then able to make sure to power up the fan when you’re working the PC hard, and you can power down the fans when you’re just using a word processor to create a document for school or work.

How can I control my PC fan speed?

There are several ways to do this manually.

One way is to go through the motherboard BIOS. This is rather inconvenient, especially when you have change PC fan speeds while you’re working with your PC.

Another way (that’s much easier) is to use software, such as the software that comes with your fan controller. There you can adjust the setting for the PC fan speed as you see fit.

There may also be some manual controls you can use right on the fan controller itself, such as knobs or even a touch screen, to help you control the fan speed.

Differences Between 2, 3 and 4 Pin Fan Controllers

Some fan controllers today can deal with several different types of fan pins. They may be able to handle both a 3-pin or a 4-pin design.

In the old days, you had to do with 2-pin design. These 2 pins were for positive and negative current flow.

But the 3-pin design added the new feature of rpm monitoring. Now you’re able to check on the how fast your fans are moving, to see if they’re working as they ought to be. If your PC is working intensively, then you’ll want to see the rpm rising accordingly.

With a 4-pin design, you also get PWM, which stands for pulse width modulation. This is basically an on/off switch, and it continuously cycles through on and off states to regulate the power for the fans.

That means your PC can then automatically regulate the speed of the fans, to match them with the temperature readings.

Is this crucial? Perhaps it’s not absolutely necessary for regular case fans, as they can just rotate at a particular rpm speed should be enough for most circumstances. But for CPU and GPU coolers, this function can help a lot in keeping your PC components happy.

Besides, even your case fans can become more power-efficient with this feature. And it also helps things go quieter, when you don’t need the fans blasting when it’s not needed.

FAQs

Are fan controllers worth it?

For the most part, yes. The fan controller makes it easier for you to set up and use your fans.

Also, you’re then able to adjust the temperatures your PC works in, which then allows you to improve the lifespan of your PC. So, it’s a worthwhile investment, since you can get more working time with your PC.

What is normal CPU fan RPM?

The “normal” CPU fan rpm depends on several factors, including the size of the fans and also what you’re currently doing with your PC.

In general, you just have to match your CPU fan speed (the rpm) to keep the PC from overheating. That means the normal temperature you’ll want to maintain is about 40 to 65 degrees.

Should I run my PC fans at full speed?

If you’re doing a lot of intensive work with your PC, then your PC temperatures will rise. For really hard work, like complicated games or using Adobe Premiere, then your PC should run at a faster speed to compensate.

After all, the basic equation here is that more rpm = more cooling.

But if you’re just using a word processor or reading news articles online, you don’t need to run the PC fans at full speed.

Don’t forget, more rpm = more noise!

Do you need a fan controller for case fans?

A fan controller isn’t absolutely essential for case fans. But then again, the fan controller can make these case fans more power-efficient, while it also keeps the noise down.

Does the motherboard control case fan speed?

Ordinarily, yes. To adjust the case fan speed yourself without a fan controller, you have to go through the motherboard BIOS.

Do you need a controller for RGB fans?

That depends on whether the RGB fan works with your motherboard. Some RGB fan kits already come with their own controllers, along with proprietary connectors.

If you’re adding a new RGB fan for your PC without its own controller, then having a controller for it makes it easier for you to monitor and adjust.

Conclusion

With lots of people these days installing numerous fans on their PCs, it’s simple enough to understand the need for a fan controller to make sure that all these fans are working properly. In fact, a fan controller makes it easier to install these fans in the first place.

Just get the best fan controller you need, and then you can make sure that your PC doesn’t overheat!
