[FAN] GPIO Pin

simpleacc

Hello,

I am new in this world and need some help
I have an Orange PI Plus 2 and bought a CPU fan (2 pins - 5V)

I connected it into 5V pin but it is very scandalous jeje. Also, I connected into 3.3V but still doing some "noise".
My question is... If I connect the fan into GPIO Pin (3V), can I lower it to 1V for example?

Which is the correct pin for this?

Thank you in advance .
(I did not find anything... Is so hard find OPI doc.)

Hmmm... I can see this: https://github.com/zhaolei/WiringOP
But... how can I do a "simple switch"? Just to turn off/on a Pin. Any special command? For example, if I want turn off GPIO.21, how can I do it?
Sorry for this newbie questions...

However, you need to read about ports (  https://github.com/zhaolei/WiringOP  &  http://www.orangepi.org/orangepibbsen/forum.php?mod=viewthread&tid=1539&extra=page%3D1
