Thermaltake's Pure Duo 14 ARGB Sync is a PWM controlled fan with addressable LEDs and 16.8 million colours. Radiators in particular benefit from its very quiet operation and low heat generation thanks to the self-lubricating hydraulic bearing. The 9-blade design allows a very high airflow and efficient cooling. The anti-vibration pads also ensure low noise levels. As the sealing cap prevents the lubricant from escaping, a long service life is also guaranteed. The two rings, each with nine addressable LEDs, are independent of each other and impress with an even light coverage and high colour intensity. The extensive effects give your housing the finishing touch and give it a unique look. Using the included controller, which does not require a 5V ARGB port, seven breathtaking effects can be selected. Alternatively, the fans can be connected to a 5V ARGB port on the mainboard and synchronised via compatible software such as AsRock Polychrome, ASUS Aura Sync, GIGABYTE RGB Fusion and MSI Mystic Light Sync.
