Extremely beginner Builder here. From what I can understand this case has 5 case fan spots, I planned to have 2 140mm fans on the front, and running them as intake fans, and then running the fans in the back as exhaust. I have no idea what to do with the fans I'm going to put on the top. Also I just want to know if the fans on the front should actually be 140mm? i was not able to find a concise answer to this on the product info page.
I already bought three 120mm fans for the top and back. Please inform me is a was wrong about those sizes.
Offtopic question: I plan to overclock my GPU(the MSI DUKE OC 2080), Will i need a aftermarket cooler or will the stock coolers be enough for overclocking?
