Rainer over @ Teschke.de send words that he has finished his review about the RSG power supply, which works without any fans.
Here´s a snip from the review:The RSG powersupply seems to work very well . We didnt notice any instabilities, even under 3D applications which needs the full power of every component working in the system. During working with standard applications the temperature was approximately 38° C . The black heatsink (outside the case) has a very practical value because it transfers part of the heat outside the case. Read the review over here
