Eric.......These two fans pull air from the cabinet. They draw enough air from the cabinet to keep the metal grill on top nearly cool to the touch. In addition, the control room is kept at a comfortable 74 degrees which adds to the efficiency of the fan's cooling effect on the interior of the wooden cabinet. There is no issue with overheating.
My original MA230 that I owned back in the 70's did not have fans. I kept the MA230 in an identical cabinet. The metal vent in the top of the cabinet got hot as hell over the power tubes. In fact, over the years of use the grill had four discolored circles in the metal from where the heat off the tubes had cooked the finish. As you can see from my photo above, there is no discoloration on the metal vent in my current McIntosh cabinet. I can place my hand on the metal without discomfort and it is barely warm to the touch. The two SilenX fans do a fine job of evacuating the heat.
