An excellent, quiet choice for heatsinks and radiators The wide body, low-pitch blades of the SP120 fans combined with the custom housing provides outstanding static pressure and airflow through heatsinks or radiators. With rubberized corners, a quiet and reliable Advanced Hydraulic Bearing, and PWM support for increased fan speed control, the SP120 truly is the strong, silent type. Included in the box are the three user-replaceable colored rings, in red, blue, and white, so you can customize your fan to match your case's components. Each fan also features blacked-out wires and connectors, so your build looks elegant and clean when done. Available in single and twin packs.
