Hi i am building my first pc and the end of this year and my case (Aerocool P7-C1 Tempered Glass Mid Tower Black) only comes with one fan. I will be purchasing 2 corsair red led fans (120mm) and i am not sure where to put them? The stock exhaust fan is in the rear and the case supports either 3 120's in the front or 2 120's in the top. Not sure whether i should put them in front, top or split them up. Thanks alot
