Firefly-RK3399 Aluminum Alloy Case cooling solution

Recently bought the case for the rk3399 board, it looks very nice also assembly is very straight forward.

Only thing that is disappointing is its capacity of cooling the FireFly. I now constantly run into over heating issues and I cannot get the cores to keep running at 1.5(A53) + 1.2 (A72) (Android 7.1.1), wereas outisde the case this is not an issue at all.

My board has the small heatsink as shipped with the board, this means there is only air in between the housing and heatsink. As the case is mostly closed there is no real airflow.

Is there any specific cooling solution planned for case like a special heatink that would connect to the case or so?
