no, since 3 pin fans does not have the 4th pin, which is the speed control. there for not voltage controllable.
but there is a way to work around.
i would buy one of these when i get a new computer. that way even 2 pin fan is voltage controllable.
Is that really true for a four pin connector on the board to support 3 pin fan speed control ? Judging from the structure shown in the picture, It should be only for pwm only not voltage control as its not built to change fan voltage, right ?
Thanks for all the advice and please offer me some help again !!
