This guarantees the required cooling and minimizes the noise level. YMMV . Dell sometimes swaps the wires around so that you will fry a dell fan on standard and the other way round. Check the amperage on whatever fan you’re using to make sure you’re good. General Purpose Input/Output is what GPIO stands for, and describes the jobs of the pins on Raspberry Pis perfectly. Connect the PWM wire to the Fan- pin of one of the controlled fan connectors. For simplicity, I’m going to use one of these eBay PWM controllers I’ve had collecting dust for a while. If you remote the grey sticker on the back of the fan, you’ll see the same four wires on most of these fans no matter the connector. 3-pin connectors are usually used for the smaller chassis fans with lower power consumption. They are very similar to Arduino pin portsas they can be configured to either read inputs or write outputs. The dilemma for people who want to connect several fans to a mobo pinout is the heavy start-up current - specs allow up to 2.2A per fan, and many mobo fan outputs cannot supply that much to … 0 - 10) and may result in a value of 0 not fully turning off the output on pins 5 and 6. The fan RPM (as a percentage of maximum RPM) should match the PWM duty cycle within ±10%. Since in this case we’re using a PWM controller to control the speed of the fan, I’d recommend something like an LM7812 voltage regulator since it would not require additional components (though I’d really recommend not using a linear but rather a switching regulator, preferably a nice one like from Pololu) Wire it like so: You may want to use a heat sink on this component and/or place it inline with whatever the fan is blowing on for active cooling. Dell sometimes swaps the wires around so that you will fry a dell fan on standard and the other way round. Also, fans may be either 5 volt DC or 12 volt DC fans, the table below shows a 12 volt DC fan connection All other ATX header pinouts, or BTX motherboard header pinout. I’m seeing that some of the Mac fans can simply be fed the same input voltage to this pin and it works fine (the centrifugal fan from a Power Mac G5 worked fine like this), but most of the fans will not function if you simply put a DC voltage on the PWM pin. I think if you can figure out which two wires are ground and +12V, and leave the other wires open, i.e. Learn more . £5.99 £ 5. Get it Tomorrow, Dec 4.
