Mar 26, 2013 at 0:30 | comment | added | Scott Seidman | That doc also suggests that the sense pin is pin 3 and the pwm pin is pin 4. I have no idea if that's correct, and can't take responsibility for your fan if its not. | |
Mar 26, 2013 at 0:27 | comment | added | Scott Seidman | PWM frequency needs to be between 21kHz and 28kHz according to formfactors.org/developer/specs/4_Wire_PWM_Spec.pdf . I don't know how to set PWM frequency on an Arduino, but I suspect it needs to be set | |
Mar 26, 2013 at 0:18 | comment | added | StealthRT | @ScottSeidman Its just set to 10 right now over and over again.. which should slow the fan down but its still spinning MAX speed. | |

Mar 25, 2013 at 23:54 | comment | added | Scott Seidman | That's a hair better. What does your serial out tell you pwmVal is doing? | |

Mar 25, 2013 at 23:13 | comment | added | Scott Seidman | If I may without offending, one lovely thing about the Arduino platform is that you can simply try it and see if it works. Even better, modularize your problem, and test each individual subsystem. You will learn WAY MORE about how to approach problems like this by trying them than you ever will by asking "What do you think?" Nobody should help you debug your code before you try to debug it yourself. | |
