I do not know anything about aftermarket fans for pcs, hence why I'm consulting the forum. The BitFenix Ronin has a window and I'd love for it to be green lit up inside and I also know the Ronin only comes with 2 fans so from my understanding it'd be a good idea to buy more aftermarket fans for better cooling, but I don't have any idea which ones to get of what sizes or how many. I'm all ears.
