Ok, if the front fan is a intake fan, so it blows inside, and the same with side panels, and the Rear is an exhaust fan (it blows outside),


...then when I install more fans in my CM 690,

I assume the top fans are exhaust, correct?

I also have a spot for a fan inside the case, blowing up at the mobo (it lays next to the PSU), which way?

Thanks guys
 

the_punkinator is right. The basic rule is that front and side fans are intake, and back and top fans are exhaust.

If you have a 690, the airflow is good enough that you do not need to mount a fan inside the case.
