Not cool, but quiet

At first I was a little surprised, because the CPU temperature in idle quasi equal to the temperature with the Boxedlüfter, about 50 ° C in the unventilated and insulated housing. The main difference, however, is that the smaller Boxedlüfter for ~ 3000rpm needed and therefore was much louder, while the Sella requires only ~ 1000rpm and is inaudible. If I place the chassis fan I come to ~ 40 ° C, which remain due to their volume but from a rule. Under load it rotates at about 1500-2000rpm (needed the Boxed 5000) on, the temperature is in the range 55-60 ° C, but the fan is still barely audible. When it is quiet, you can perceive it, that's all. No comparison to the high and loud speed of Boxedlüfters.

I admit that I had expected to lower temperatures, but as long as they do not move in a critical area and the computer remains silent, they may be to me ultimately care less. The loudest at my computer is now the BE QUIET Power Supply, and that's saying something)
