I just wanted a Gbit switch with many ports, efficient and fanless. And that's what this switch fulfills perfectly. All Ethernet-cans in the house are connected to this switch. Power needs a port only if really a device depends on the other side off. If no port is active, the switch needs only 3 watts. My model (bought about a year ago) has def. no fan. You hear anything at all. Perfect Home-Switch for me.
