This is the test function.
..
..
. Fan operation check only
When the FAN DRIVE is changed from AUTO to
MANUAL, and ENTER is pressed, the DRIVE DATA
indication changes to cyan. In this setup, the drive
register value can be manually modified. When the
drive register value is changed, the pulse width of the
PWM signal in the fan voltage control PWM circuit is
changed accordingly.
Fans can be checked whether they operate normally or
not by comparing the register value and the actual
drive voltage, and by comparing the actual drive
voltage and the actual operations of the fans.
Variable range of the drive register value :
00000 to 16383

. Blue only
When Blue only is selected, all of the R, G and B colors
become the blue data.
