PWM Fan works for 15-20 min then stops

#include "custom-pwm.h"

#define RESOLUTION  12    // resolution 2^12= 4096
#define FREQUENCY   300

CustomPwm digitalServo = CustomPwm(D1, RESOLUTION, FREQUENCY);

int pos = 0;

void setup() {

  digitalServo.begin();

}

void loop() {

  for(pos = 0; pos < 2048; pos += 11)  // increment about a degree each time
  {
    digitalServo.write(pos);             // e.g. 451/4096 = 11%, 2048/4096 = 50%
    delay(.15);                         // waits 15ms for the servo to reach the position
  }

  for(pos = 2048; pos > 11; pos -= 11)  // decrement about a degree each time
  {
    digitalServo.write(pos);
    delay(.15);
  }
}

Any ideas?

delay(.15) will not wait 15 milliseconds but zero :wink:
