Review: Works well - Got this for my Protectli Vault PFSENSE device ( 4 port with J3160 cpu) to cool the giant heat sink fins. Like the USb connection and speed controller, has extra usb port to daisy chain if required. Works well, my cpu was hitting about 58c under 20% load using traffic shaper etc, now its like 37c under 20% load. A bit of noise when its on high however does the job, sits on the top and stays with preinstalled nice ruber feet. Happy with the purchase!
Review: nice little fan with the speed controller - not really that quiet. on lowest RPM setting, it is still audible in my quiet room.
