The hard disk is fixed at Himura in two half-shells. On the bottom is the plate, the rear is an opening for the interface, a front pubic material block which hold the plate against the rear wall. There is no insulation between wall and plate, it is therefore metal on metal. Dämmefekt nil. The same applies to the soil, here the plate is directly and unentkoppelt on the metal. The lid is the top and side housing. There is a thin thermal pad, the cover itself a very thin layer of foam on both sides. Are lid and caseback, have apart from the cover and the foam block forward all remaining surfaces and direct contact with non-insulated plate. Accordingly, the only sound moderate difference is a slight lowering of the high-frequency engine noise, traffic coming through almost unfiltered.
In addition, the housing has play when you move it is heard inside the plate alternately strike against the cover and base plate. Not good and certainly not optimal for heat transfer, this also goes primarily over the heating pads on the sides. Nevertheless, the plate should be securely fixed, as the pressure transferring heat between two components helps quite.
Of the temperatures the whole looks quite good, the housing holds the plate approximately at the temperature that you previously "naked" and by the rubber rings from the case decouples the airflow of a very slowly rotating front fan had. A firebrand is the Samsung but eh not, the temperatures were about 5 degrees above room temperature.
In conclusion, that the housing thoroughly helps its large surface area for cooling without or with very little breeze, but a noise insulation you should not necessarily expect, this is due to lack of insulation layers between metal plate and not really designed. For comparison, the Quiet Drive a thick foam layer or on top and bottom was around a 5mm thick thermal pad, which caused a very good insulation with rather mediocre cooling. The Himura is the exact opposite.
