Sharkoon Technologies has introduced the Sharkoon SilentStorm 120 PWM and SilentStorm 140 PWM case fans. As you can tell from the numbers in the designations, the first model is 120mm, the second is 140mm. Both support PWM speed control. The maximum speed is 1400 rpm. Each model is decorated with nine addressable LEDs and equipped with interchangeable vibration dampers in two colors.
Spinning at maximum speed, the SilentStorm 140 PWM fan generates airflow of 121.9 m3/h and the SilentStorm 120 PWM fan generates 93.6 m3/h. Noise levels are less than 20dB and 35dB. The fans use hydrodynamic bearings.
Addressable RGB lighting can be controlled using Asus Aura Sync, MSI Mystic Light Sync and other similar software by connecting RGB LEDs to the motherboard or RGB controller via either a three-pin 5V-DG connector or a four-pin 5V-D-coded-G connector.
The SilentStorm 120 PWM fan costs 11 euros and the SilentStorm 140 PWM costs 13 euros.
