I am about to start on my SM8 build and am planning on a 480 rad on the roof and 360 in the front. I've always gone positive pressure on my past builds.. but with this one I am not sure if I should do the 480 and 360 as intake and only have the rear exhaust. Btw, I went with the reverse layout. Other option would be rear fan and front 360 as intake and 480 up top as exhaust..a neutral setup. Any feedback would be appreciated.
