    Simple question.

    Depends on what direction you want airflow to go..

    Depends on the chassis your using..

    Depends on components installed..

    Depends on your environment..

    Less than simple question, unfortunately

    Haha everywhere else I look it's the same thing. So I don't know if it depends.

    Top + back is exhaust
    Front is intake.

    If you already believe everywhere else, then do that.

    My only problem is that I only have 1 intake fan. Is that enough?

    I only have one intake fan on my case. But then again it mostly depends on how big the fan is.

    Depends on the hardware you are running, are you noticing things running too hot? any other negative things?

    Well I noticed I'm an idiot and my top fans are intake. I flipped them and I think my case is slightly cooler now. I just got a mid tower.

    You talk like all setups are the same.. there is no template for how things go.. it will vary on your components and other stuff as mentioned. Same with case, just cause you have a mid-tower doesn't mean anything... mid-towers vary widely.

    Well I got 2 top fans (exhaust), 1 back fan (exhaust), 1 front fan (intake), and the power supply which i assume is intake. Then just a stock cpu cooler.

    I'd maybe switch one of your top fans to a front/side intake but it really won't matter too much. Usually you want as many or more intake fans as exhaust so that the case naturally will exhaust air and you only get intake through your fans (and hopefully dust filter).

    Ok Maybe I'll switch one of the top ones then,

    You'll have better cooling if you have more exhaust than intake, downside dust (e.g. negative pressure).

    ^This. If you want to reduce dust you should have more intake than exhaust. This produces an ever so slight positive pressure in the case which will reduce dust settling inside. If your case has excellent dust filtering, this is not such a big deal.

    With 1 in and 3 out I'm sure you're fine in terms of temperature, though.
