Water/air cooling

    If this question as been asked, could you please direct me to it.


    It's about air/water cooling, it says in a 3x3 sphere, but could anyone tell me which bloc it is exactly !!!
    As of what im getting, there's suppose to be 26 of them, some help would be gladly welcomed !


    Telling me like this :


    -1 floor
    [n][n][n][n][n]
    [n][o][o][o][n]
    [n][o][o][o][n]
    [n][o][o][o][n]
    [n][n][n][n][n]


    0 floor
    [n][n][n][n][n]
    [n][o][o][o][n]
    [n][o][x][o][n]
    [n][o][o][o][n]
    [n][n][n][n][n]


    1 floor ...


    [n] : non-cooling bloc
    [o] : cooling bloc (if water 1, air 1/4, something 0)
    [x] : reactor


    EDIT : Added color (just more easy to see that way)

    I take it you are meaning a 0-chamber reactor? If so, the -1 floor and +1 floor would be the same. It looks like your diagrams have the right idea.
