I have a dual 800 g4 and the case fan has begun to sound like it has a problem. i got a replacement fan but when i went to do the swap i noticed that the old fan is blowing air towards the rear of the unit, in other words, not drawing air into the case but blowing it away from the mb. i thought the fan in the power supply drew the air out and it is, but i always figured the case fan brought in the outside air through those small metal holes on the side where the fan sits.
which orientation is correct?
thanks for any input.
