It is. Has no heat problems at all though I disconnected the rear fan of the case, that just came to my mind… it wasn’t loud but I did want it to be silent.
It has no heat (and therefore fan noise) problems probably because the CPU is idling on 30% when my ASIO load of a project is near red 
Don’t want the possible noise but I’d be happy if a future Cubase could somehow improve that ratio!
