I am planning to make a two thermistor version of etech's/ particle moth's fan control circuit here using a dual op-amp and using a IRF530 equivalent to the BUZ20.<P>Fan control w/ all the bells and ...

A cooling system can sometimes be a buzzkill. You drop your badass engine into your badass hot rod, and then you remember you've got to keep it cool. As an afterthought, you order a big aluminum ...

PWM or Pulse Width Modulation has generally been regarded as too complicated for PC fan speed control compared against using rheostats or linear voltage regulators such as the LM317. I present here a ...

A few weeks ago, I saw a reader’s question about how to run PS3 cooling fans using an external electronics circuit. At the time I was busy with some other projects. The other day, I decided to put my ...

How to build a proportional controller that starts a cooling fan when circuit temperature passes a threshold, speeds up the fan as the temperature rises, and slows down and stops the fan when the ...

This Processor Fan Control circuit is intended to be used with relatively old PCs, since more recent models generally have a fan control circuit already integrated into the motherboard. These ...

Given that you could run 5-6 fans off a single header without overloading it, it seems to me the main reason to go with a controller rather than a splitter would be to make the wiring easier.

When implementing cooling solutions for electronic equipment, system designers are confronted with a complex set of variables. The cooling requirements are typically dynamic, and ambient temperatures ...

I was pondering possible interfaces between a microcontroller and a 12 or 24V 5015 blower fan. The challenge is that the MCU can only drive 3.3 or 5V, while the blower needs needs a voltage as low as ...

The Leviton Decora Smart Wi-Fi 4-Speed Fan Controller is a very, good product; it just isn’t the best in its class. I used to recommend picking one smart home ecosystem and sticking with it. Start ...

Here is an example of the built circuit on a small piece of stripboard. The 2p coin gives an indication of size. I have not included the diode D1 in this example. Side view. General layout of ...
