Just purchased the Corsair Hydro Series H115i and I want it to exhaust air from my case, is this the correct or recommended setup for the fans? Also looking to replace the stock fans with something better but with a red theme. Would the Corsair SP 120s be a solid choice? And is 120 the right size or should I be looking for 140s? Any fan recommendations with a red theme would be greatly appreciated. Thank you all in advance.
