I have mine sitting on the top of the rack so thers nothingabove it,after watching one movie it is very hot to touch when i put my hands on the top of the case,Is this normal?,Does yours or other owners of this reciever do this,i run lasclas for the mains,i am surprized they put no fan inside the case for cooling,You would think the internals would start to break down after years running this hot,I just might get a cooling fan for the top to suck hot air out.
