Schematic: fan pin assignments

[msladen]

Hi Jack,
I have a project that I set aside, and am just getting back to. Amplifier controller, but it incorporates a fan control, and I was looking at your project for reference. I saw that on your schematic you show power and ground going into the fan through pins 3 and 4 respectively. Other documentation shows pins 2 and 1 for 12v and ground, including the original Intel pwm document, Since these are often implemented in headers that can be plugged in either way, it may not matter, but plugging the connector in the wrong way will probably fry it. Suggest you change the pin designations on your schematic.

I suspect that I incorrectly named/ordered the pins as 4 through 1 instead of 1 through 4. The actual hardware should be correct (has worked for me for years), and I can correct this in the schematic for the Simple 003 schematics.

Thanks for reviewing the project.
