I'm really not sure what to have positive vs negative. My case is a NZXT Tempest 410 Elite http://www.newegg.com/Product/Product.aspx?Item=N82E16811146080, it has 2 NZXT 120mm fans on the front and 1 NZXt 120mm fan on the back. So I'm wondering if I add another fan should I get 1 or even 2 more exhaust on the top, or an intake on the bottom?
Thanks!
