1x200mm front intake, 1x140mm rear exhaust. Where should I put my extra 140mm? Bottom intake or top exhaust?

Noctua NH-D15
Phanteks Enthoo Pro

The Phanteks Enthoo Pro comes with a 200mm front intake fan and a 140mm rear exhaust fan. I'm planning to buy an additional 140mm case fan. Where should I put it?
