I'm building my first pc, and I don't know what direction to put my fans in. Currently, the case I have is the Fractal Design Focus G, which has 2 intake fans in the front. The instructions for the H60 recommends to put the H60 fan as intake, but then I would have no fans as exhaust. Is having all my fans as intake fine? Should I put all my fans as intake, put the H60 fan as exhaust instead, or should I buy some more fans as exhaust? If I need more fans, what fans should I buy and how many should I buy? This is my first pc so I don't really know that much.
