However, they do bring a bit of bling with various color options, including red, white, green, and yellow trim. >Starting with the fans, the Bionix come in 120mm (Bionix F120) and 140mm (Bionic F140) sizes. These are PWM fans that can spin anywhere from 200 to 1,800 RPM, powered by a low-noise motor for quiet operation.
