I switched to this case after zalman i3. In appearance, AeroCool does it in all aspects, but the Zalman itself was quieter, perhaps due to other turntables, but they + everything could be turned off if necessary. In AeroCool, they will work constantly and at medium speeds. Perhaps I did not understand the controls, but even when the control unit was connected to the motherboard, I could not reduce their speed. In general, the body is good, but it needs to be improved, its price is currently too high due to PR
