Noctua NA-FC1, 4-Pin PWM Fan Controller (Black)

Product Information

Choosing a fan controller is simple. Just list your needs and see which controller fulfills them at the best price. Still, there are some details you need to focus on, especially if your PC case is filled with RGB and non-RGB fans and with both PWM and non-PWM fans. Same-Brand Controllers Are Best For RGB Case Fans The one downside of HWMonitor, though, is that the user interface is a bit clunky. It might take you a while to get familiar with the columns of numbers in front of you. But once you know your way around, you’ll never want to use another application. If your case has both PWM and non-PWM fans get a fan controller that enables PWM control for non-PWM fans. This way your non-PWM fans won’t run at max speed all the time and your motherboard will be able to automatically set their voltage and speed.

Corsair iCUE allows you to synchronize the RGB lighting on all of your compatible corsair devices. There are four waves of light to choose from: Rainbow, Yellow, Rain, and Visor. Components are identical to the 555 circuit but are labeled differently in this schematic: C1 = 680pF; C2 = 0.01 μF; C3 = 0.1 μF; C4 = 10 μF, polarized. There is also an extra resistor (R2) which has a value of 10K.) Cooling fans are a vital part of computer hardware, as they cool the CPU and ventilate casing, enabling active cooling in computers. All computers have built-in fans, as they are one of the approved cooling mechanisms for processors. The fans in computers gather cool air from the ambient and expel the warm air outside. They also aid the working of heat sinks by distributing air across them. Here, we discuss two types of cooling fans— Pulse Width Modulated (PWM) fans and DC fans.

Sample & Buy

And remember: This circuit uses 5v, NOT 12v. Step 5: Debugging Digital Multimeter – a must for testing circuits and components Flexibility: Normally, computer fans are not particularly calibrated to respond to the computer’s internal state. As a result, most of the time your fans are running more than they need to be. Pulse Width Modulation (PWM) is a nifty current control technique that enables you to control the speed of motors, heat output of heaters, and much more in an energy-efficient (and usually quieter) manner. Existing applications for PWM include, but are not limited to: https://github.com/medevil84/FanControl.AquacomputerDevices to interface with aquacomputer HighFlowNext, Quadro and Octo devices Q: There is no control cards / control cards are missing / control cards are not changing my fan speeds, what's the issue?

The squares in the PWM illustration below are the pulses which represent ‘on’ time, and the depressed areas represent the time that the power is ‘off’. Both the squares and depressed areas are the same ‘width’, therefore the duty cycle is 50%. PWM signals are typically square waves, like the one in the illustration below. A PWM signal (square wave) with a 50% duty cycle. A: You want to avoid any "smart" control from your BIOS. Setting a fixed default speed, like 50%, works great for most people. Also keep an eye if your BIOS has PWM or DC mode on. One could work better for you depending on your setup. The exact specs of these fans were made by Intel in the mid-00s and are available here: Original | Latest version | Noctua Connecting the fan to the Arduino The box for the 556 circuit, complete with stylish aluminum pot and Molex connector for convenience HWMonitor is another program that has been around for quite a while. And during that time, it has distinguished itself and cultivated a userbase that keeps growing. HWMonitor does everything the other programs do and then some.

Design Resources

Timer 0 (Pins 5,6) is identical to Timer 2, so we could apply the same settings that we used for it and get an extra output for a fourth fan; however, it is used for all timing functions such as delay, millis, etc. and touching it would cause everything that depends on this to behave erratically, including our Serial output. My code doesn't touch this timer. DC fans are supplied with DC power from regulated DC supply or motherboard header pins. These fans are also called 3-pin fans, as they come with 3 pins: a supply pin (usually 12 V DC), a ground pin, and a signal pin. If you have a 5V fan, you can power it directly from the 5V pin on the Arduino, but I don't recommend it if it draws more than 4-500 mA, as it could damage the voltage regulator on the Arduino, and also generate noise that could cause the Arduino to be unstable. If unsure, power the Arduino and the fan in parallel with a 5V supply connected to both the fan and the 5V pin.

When the time comes to make a proper circuit using scary grown-up tools like a soldering iron and a pair of wire cutters, it is definitely worth your while planning the layout of your circuit once again and trying to make it as compact as you can. If you have space on your stripboard you might want to consider soldering a 4-pin fan header onto it to keep the controller tidy and practical. The same efficiency rule that applies to resistors also applies to transistors— Their resistance results in wasted energy because they burn off some of it as heat. They act like heaters in that regard. Computers have been using PWM-controlled fans for ages now (they're the ones with a 4 pin connector). This allows the BIOS to change the fan speed according to the current temperatures using a PWM signal instead of changing the voltage of the fan, which means that motherboards are cheaper to make (less voltage regulators), but also that fans are much easier to control, since DC motors won't even move below a certain voltage threshold.The downside is that the controller has only one PWM channel, using data from the fan connected to the Fan 1 connector. This is a great solution in case you have both PWM and non-PWM case fans and want to control them all automatically. The RPM of the first fan connected to the fan slot is read and returned to the system, setting PWM signal synchronously to all fans. Included in the box you'll get two adhesive EVA pads, two adhesive magnet pads, and a SATA cable. When your system needs cooling, all of the fans will work at the same time, however, if you only want some of your fans to spin, you'll need to disconnect them. https://github.com/EvanMulawski/FanControl.CorsairLink to interface with Corsair Commander controllers and Hydro liquid coolers I’m sure that most hardware enthusiasts are no strangers to dalliances with DIY, whether it be case modding, component modding, or custom cooling. However, when it comes to building parts of your computer from scratch, the tally of enthusiasts who can claim this prestige most certainly diminishes. Fortunately, this neat fan controller project requires only a little time, expense, and commitment, and the circuit is relatively easy to build and very satisfying to use! First Things First…What is PWM? Note: A fan curve is a chart visualization of fan speed and temperature. Using the chart, you can set the fan speed according to the temperature. Follow these steps to create your own fan curve.

The software is completely free to use but the developer (Rem0o on GitHub) does accept donations. And, considering that Rem0o was able to create a truly all-in-one fan control program where many other professional developers have come up short, it wouldn’t hurt to throw a donation their way. Aspiring electrical engineers may want to know why they should use pulse width modulation to control devices, and homeowners have similar question which has the same answer: Why use inverter air conditioners, or other variable speed appliances? Corsair iCUE is software that manages all Corsair products on your computer. This software monitors the real-time temperature, creates custom lighting effects to alert you when temperatures rise, and also controls fan curves to change fan speeds. Note: SMART (Self-Monitoring, Analysis, and Reporting Technology) is a hard disk monitoring system that provides information on a drive’s status.

A good fan control application makes it easier to tune the CPU and GPU fans for maximum performance with minimum noise. Keeping this in mind, we have listed some of the best fan control software that you can use. MSI Afterburner (For Windows)
