About this deal

I have an unusual situation in that there is enough heat coming off the memory in the chassis that CPU loading isn’t always the dominant factor determining internal temperature, and consequently CPU temperature. The fan header refers to the port on your motherboard that you can hook fans up to. Most computer fans come in a 3-pin or 4-pin design, each number referring to the number of connector pins.

Because the operating characteristics are selected by hardwired passive components, a simple, low-cost fan-speed controller can be implemented without the need for firmware development. This can dramatically reduce development time for the fan control function. Now before you allow yourself to become intimidated by the above schematic and all these different components, make sure you are taking a calculated approach to the process of putting the circuit together. The best thing to do is to take it one step at a time. Having done it myself (several times), these are the steps that I find most conducive to a hassle-free workflow:Deep Shrestha works as a computer hardware writer at TechNewsToday with several hardware and programming certifications. On the plus side, these fan controllers are a lot of fun and can be very useful if you regularly benchmark your system and require powerful cooling at the touch of a button (as I do). Here’s a short video which shows the capabilities of the 556 circuit when paired with some seriously powerful 120mm fans…


Note that the official spec says that the minimum duty cycle for the fans should be 20%. Decent fans like the Noctua ones I used in my tests can take any duty cycle, but you should keep it in mind if you're using cheaper fans. RPM detectionI’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? Fan Control is a stand-alone app. You can leave the files there for use further down the line, or delete them. Plan your circuit on a piece of paper, familiarizing yourself with each component (learn what it looks like and what it does) and the layout of the circuit, and taking time to arrange it in such a way that it is clean and clear.
