Cryorig's QF120 Balance lies between the Performance and Silent models, giving you the best of both worlds. While keeping quiet, it still pushes a good amount of air through your system. The RPM ranges from 330 to 1600 RPM, a good balance for everyday PC use. The Quad Air Inlet system provides additional open space for air to be taken in, areas where your average fan just has the frame. Rubber pads mounted where screws or pins will further reduces the noise level the fan makes. Use it as a system fan or CPU fan; it is well-suited for both applications.
