I agree. The cooling design in the CCR 1036 and 1016 is not perfect
There is a single front to back shroud over the CPU. This means the processor is cooled excellently!
However everything else (RAM, Voltage Regulators, PSU, SFP's) relies on passive cooling in to aan almost closed cavity.
A simple low cost design solution would be to punch a grill into the alloy back or sides of the CCR to let the warm air out. .
I will add that the cooling design on the CCR1072 is much improved over the earlier CCR models
