There could be several changes needed.
Can you reverse the fan ?

no i can't...m using a high speed c.p.u fan to rotate it...

reverse the voltage connections it should rotate fan in opposite direction then.

That may not work.
Those motors usually use a stepper motor type design.

I think CPU fans are normal BLDC type motors.
