Since the built-in CPU cooler Scythe Mugen 4 (he also runs at full load with 580 U / min) and d PSU fan is inaudible, the only noise source is in the PC, a Western Digital Green hard drive that I have installed in addition to an SSD. The case fan I according to c't recommendation not connected, because there is enough circulation because of the many ventilation holes.
The hard drive mounting is unfortunately a weak point of the case. The hard disk must be inserted on the left, and the cables are connected right. So you have to dismantle both side panels. The hard drive is very tight fixed, while the access noise is transmitted to the entire body and are clearly audible. I have therefore decided the hard drive in a Sharkoon HDD Vibe-Fixer be mounted in one of three 5.25 "-Schächt what is ideal place but because of Lüftung.kein.
A second weakness of the ventilation holes, in particular in the upper part, which can be freely dust into the housing. There are by the company Demciflex a Staubfilterset which was cut to size for the Carbide 200R, however, will cost almost as much as the body itself. When I built in hardware but I can safely holes in the top cover completely airtight without the temperature inside rises.
