    Use the bigger of your fans to pull air out the top through your light and depending on your setup you can use the other out the top through a filter or as an intake...personally I only use 1 can fan style on my whole setup with a passive intake

    i tried runnning the fun blowing into refelctor still got up to 93 i think the light is just either too strong for such a small box or i need to get a air cooled hood so i can actually run air around the bulb....

    both should be exhausting from the space, passive airflow into the growing area is how you want to run it.

    The more your fans suck, the greater the negative pressure is inside of the tent/room, that pulls in fresh cold air from a supply vent or under the doors into your room and back out of the light

    this guy is right. i would use both fans for exhaust and just have open holes that are twice the size of the exhaust holes
