    it depends on where the fans are pointing

    also it could be that the fans are keeping hot air inside the case instead of letting it out

    try unplugging the fans and see how it affects the temps

    i have 2 120mm fans-one is the front, pushing air in and one in the back, pulling air out, 2 80mm in the in the psu blowing out, 1 80mm on top windows pushing air out, 3 80mm fans on the side window pushing in

    see what happens to the temps when you unplug the fans in the side window

    if you have a fan blowing over the cpu then that should help your temps but also if the other fans are keeping the hot air in then it can raise your case temp which is turn can raise your cpu temp because hot air is being blown onto the hot heatsink so it doesn't cool it down as much as cool air

    the ideal method
    same cfm in same cfm out
    front cool on the bootm in
    back hot as close to top out
    I have 2 fans pulling in across drives
    2 fans on cpu's
    the psu fan out and another fan out
    case at 38c
    cpu's at 35 working not idle
    thats my story and I'm stick'n to it

    air flow is specialy designed to send hot air from the front of the case to the back, so check your directions of were the fans are pointing, or maybe there are so many it is caussing a disturbing flow and causing more heat to generate, eather way good luck with that
