I have a total of 3 fans for my case right now and I don't know if it's enough or if it's arranged well. I have a front 120mm fan that intakes air. I have an 80mm fan on the side window panel that exhausts air. And I have a rear 120mm fan that exhaust air. Does this seem right? I've seen some people do the same thing but the side panel fan intakes air instead of exhausting it. would this work too? would it get me better temps?
