amount of heat at the back of these board (all z390 boards) is quite hot, specially if they are using doublers , which half the time is mounted at the back and explains the heatsinks
wonder if we'll start to see a change in case design to get airflow to the back side of boards
I've seen some boards that have a small fan under the shroud next to the backplate. I guess we might see more like that as time goes on.
Asus also has a fan built into an AIO block to cool VRM's now also.
