Human: Dual Fan Cooling System for Alfawise U20/30 v2.0 (review of https://www.thingiverse.com/thing:3767237).\r\n\r\nIt uses three 40x40 fans (12/24v) with a spacing of about 31.5mm between holes.\r\nThe intake mouth is 38mm in diameter, with walls shaped like X inside the channel for approximately 20mm (useful to stabilize air flow without creating vortices...or at least limiting their formation).\r\n\r\nThe channel is approximately 100mm long and allows a good vortex of the air to improve its exit flow.\r\n\r\nIt integrates a cable support and canaline...there is an anterior hole for connecting the front fan directly in the rear area without having cables in front.\r\n\r\n
