Deepcool GF140 is a round frame Hydro Bearing 140mm fan, 26mm thick that comes in Green and Red color options. Its operating voltage is from 10.8～13.2VDC achieving speed of 700±200~1200±10%RPM. At 1200 RPM it pushes around 71.8CFM with noise level of 26.7dB(A), where the lowest noise is 17.6dB(A). There is PWM connector on the fan cable, meaning that it could be system-controlled. Another nice touch is that the cable itself is made from PTFE (Poly Tetra Fluoro Ethylene), which is fire resistant.
The fan frame is covered with TPE (Thermoplastic Polyurethane Elastomer) that absorbs vibrations, allowing for silent operation. Airflow is optimized by implementation of AACC technology (Airflow Auto-Control Channel) on the fan blades.
