This wall mount has 2 screw holes for mounting the pi to a surface and 4 raised screw holes to mount a 80mm fan above the pi. The pi will be uncovered and the ports will be outside the mount area. This way the cooling air from the fan is only directed at the parts generating heat. I recommend to use fans that can start at 5V and only use them at 5V to have little to no noise. The 80mm format should blow more than enough air over the pi to keep it cool.
