Big Boy / alfawise U20 silent fang 80 mm fan
thingiverse
I've installed a very quiet cooling system for my alfawise U20.\r\nI replaced the two small and loud original fans with an 80 mm Noctua fan.\r\nThe new fan is connected to the heating block's fan wiring, with two resistors provided with the Noctua fans added.\r\nIt cools the heatsink and the freshly extruded filament.\r\nNow I only hear the motors.\r\rnThe photos show the old version.\r\nThe V4 will be photographed soon, once the printing is finalized.\r\nI fixed the tube that blows onto the filament. (it should no longer blow on the nozzle...)\r\n
