I drilled 3 x 120mm breather holes in the front of the lower skirt of my ARB bar as there was very restricted cooling air entry...especially with quite large spot lights and a winch in the way of air flow. I also drilled some smaller 25mm holes at the bottom of the skirt to assist air movement....and allow water etc to drain out...all good.
