Is something missing from my gimbal?

I was watching the DJI official video for the firmware update and noticed something at the 2:20 mark. There appears to be a fan on the top of the gimbal. My P3A doesn't have this, it simply has a vacant area where this would go. Is this something that is exclusive to the P3P?
