Do you like to tinker with your tech; or modify and adjust things in your PC to take advantage of your tech’s full potential? If so, we not only understand – we want to introduce you to a whole new level of efficiency and ‘cool’ – the best fan controllers money can buy. You want to get as much bang for your buck as you can, and with just a bit of research (and tinkering, of course) you can dramatically improve your computer’s performance.
It’s exciting to push your PC to the max and see what it can really do when push comes to shove. Gamer’s and tech enthusiasts typically start out by finding and installing the best motherboard, CPU, graphics card, RAM, best CPU coolers and the best case fans for their system. This makes a lot of sense, since these mods are amongst the simplest to research and perform yourself.
What are you doing to protect all of that shiny new tech though? Even if you use the very best thermal paste, cooling systems, and case fans, there are additional steps that you can (and should) take to protect your gear. If you haven’t looked into fan controllers before, there’s no time like the present.
When & Why You May Need a Fan Controller
While fans are highly crucial to the entire cooling process of your PC, they’re also a notorious hassle in several ways. Noise made by fans, for instance, is a major contributing factor to user dissatisfaction. Noise is caused by two main factors-
- Dirty fans are not only loud, they’re insufficient. If your fans are clogged, they are certainly not providing enough air flow to keep your CPU, GPU, and other important components at optimal temperatures for performance. We recommend a good a good cleaning from time to time and this article by PC World is a great reference on how to do so.
- Fans running at high speeds can be quite bothersome and loud as well. If your system is running hot, however, there isn’t much that you can do about this particular problem without the assistance of a modern fan controller.
Having a controller for your fan(s) makes it much easier to monitor the temperature of your multiple PC components so that you can safely, manually adjust your fan speed without overheating the system. The most popular method of using a fan controller involves altering the fan’s duty cycle so that it only receives power in short bursts to keep the fan moving. In between these waves of current, the fan is almost completely silent.
What Makes a Good Fan Controller?
There are a few different things to consider before purchasing a new fan controller. After all, you want to make sure that you’re getting the best pc fan controller for your PC. Of course, you’ll want to consider the following:
- Aesthetics. The look and design of a fan controller may or may not be your main priority, but it’s worth note that there are some VERY cool models available.
- Controls. The controls for these devices vary widely. Some are as simple as a rotational dial on the outside of the PC case. Others provide brilliant, LED screen displays, some of which are even touchscreen.
- Pins. The number of pins that a fan controller has, dictates how the control device operates. There are 2, 3, and 4 pin models; the 4 pin being the most common in mainstream devices.
Understanding the Differences Between 2, 3 and 4 Pin
- The 2 Pin model is outdated, but still considered relative efficient for systems requiring only basic cooling. Of these 2 pins, 1 is for positive current, and the other is your ground connection; or negative current.
- Models with 3 pins are slightly more sophisticated. The first 2 pins perform the same functions as those above (negative and positive current flow), but the third pin makes a world of difference in functionality. The third pin conveys information about the fan speed; or RPM to the user for monitoring purposes.
- As you might suspect, a 4 Pin performs all of the same tasks as a 2 or 3 Pin. However, the fourth pin is what really makes a fan controller stand out. This model is otherwise known as a PWM model, which stands for pulse width modulation.
It isn’t as complicated as it sounds, it is essentially just an on/off switch run cycle. The PWM signal either allows a full +12V current to run to the fan, or cuts the power completely. You control the duty cycle of your fans with the controller and if you’re curious to learn more about PWM, EKWB does a nice job of explaining it with plenty of diagrams in their article, “What is PWM and how does it work?”
