When i run lcdc and click start display the fans quickly flicker every second. Its hardly noticeable but slightly annoying. Any ideas? my fans are running at 50% speed and minimum pwm is 50 but the higher it is it dont make much difference.

What display do you have? We have a bunch of different fans here and have yet to find any that "flicker"... what brand of fans are they? try turning up the PWM frequency on the GPO... do the fans flicker at 100% speed?
