DC fan directly to Arduino?

-

hello, want connect cpu fan arduino have software-controlled ventillator.
my problem is: not own power fan with, , low 5v output isn't bad of option, need working fan spins , creates little bit of airflow.
is possible connect fan directly arduino without breaking it?
any appreciated!

no. arduino not designed power more few leds, , motors create electrical noise can damage chips. use separate power supply motors or servos , connect grounds.
