Next we will need the bottom half of the cooler.You want to put the cooler up on 1 end and in the center up high but not interfiering with the lid closing make 2 holes about 1 inch in diameter ( these can vary some if you have no hole saw or spade bit you can cut a slit about 4 inches long 1 inch wide.This will allow air to be sucked into the cooler by the fan which is sucking cool air from inside and expelling it into the room.You can also add some flex hose to the inline fan and vent it right into a small grow box or area.These will cool grow boxes nicely and even a small room will be able to have a noticeable temp drop.I used 3 of these in an 8 x8 room and got a 15 degree drop.Your coller should now have these intake holes like these pictures...
