These fans haven't been officially announced yet but Newegg is already selling the 120mm version of the Corsair LL series. This is a new line of fancy RGB LED fans, they feature a dual RGB lighting loop with 16 independent RGB LEDs.
The LL120 RGB PWM fan promises low noise and has dynamic fan speed control from 600RPM to 1500RPM. It has hydraulic bearing and pushes a maximum of 43.25CFM of air at a noise level of 24.8dBA.
The 120mm version is sold for $34.99 and you can get a pack of three with the Lighting Node PRO for $119.99. Corsair says the single-fan edition is intended as an expansion of the LL120 RGB LED 3 fan kit, because you need a RGB Lighting hub and Lighting Node PRO to use the RGB functionality. Models with 140mm fan size are expected to follow soon.
