Zalman ZM-DF12 Smart Fans Begin Selling
Zalman's most advanced fan, the ZM-DF12, started selling. Built in the 25 mm-thick 120 mm form-factor, the fan features a 'dual-impeller' design, which works to increase air-flow, at lower speeds. The dual-impeller is basically two sets of blades spinning along a common motor. The motor features a nano-polymer bearing that has lower thermal deformation over time than common fluid-dynamic bearing types. The fan features a 'reversed' frame assembly. The frame holds the hub from behind, rather than the front. The back part of the motor hub hence doesn't spin along with the impeller. It instead features the fan's in-built controller, that lets you control speed in three steps - 800 RPM, 1,200 RPM, and 1,600 RPM. The fan takes input from a 3-pin connector. At its maximum speed, it pushes 63.76 CFM of air, with 33 dBA noise output.
