I bought a new case fan and I need some help with where I should place it. I currently have one intake at the front and one exhaust at the back. Should the new one be placed at option 1, 2 or 3 as an exhaust or intake fan? (Option 3 is the side of my case) Or should the most powerful fan (the new one) replace the current rear fan and just put the replaced one in one of those options?
Any help is appreciated.
