hello I have an corsair 460x case and also a corsair h80i v2 120mil radiator cpu cooler... I want to know is it better to use it at the back of the case with push pull and let it exhaust at the back or but the radiator in the front of the front fans? and also what is the best fan config if I have 7 fans for my case (2 for the radiator) and please tell me what position all fans should be placed for best temps ( my room is hot at day time so want the best for what I can do) thanks.
