Hi all!

So I currently have a Thermaltake Core X31 https://www.thermaltake.com/products-model.aspx?id=C_00002786 case, and was looking through some of my extra computer parts and realized I have an extra case fan (a noctua NF-F12 PWM). And so, I was thinking of installing it on my case. But I am not sure where to put it. Should I put it at the top as an exhaust or at the bottom as an intake? Or somewhere else? My current fan setup is this; I have 1 120mm fan on the top middle of my case as an exhaust , 2 120mm fans at the front as intake, and I have an CORSAIR HYDRO SERIES H75 AIO Liquid CPU Cooler https://www.amazon.ca/gp/product/B00FZHWFEW/ref=oh_aui_search_asin_title?ie=UTF8&psc=1 with a 120mm radiator/fan combo in the back.

Should I install my extra fan somewhere or should I just leave it how it is?
