In addition to a wide control range, the Alphacool Rise fan also offers outstanding digital RGB LED lighting. The individually controllable 5V aRGB LEDs paired with the special design of the fan create unique effects. Brilliant lighting 20 digitally addressable 5V RGB LEDs are installed in the frame and hub that illuminate the entire fan. This creates a unique lighting that looks very noble. Thanks to the recessed diffusers, the light is evenly distributed. Selective illumination is thus avoided. Individual LEDs are no longer recognizable. Wide control range and silent The fan can be controlled from 0 to 2500 rpm via the 4-pin PWM connector. In addition, it offers zero control, with which the fan can be regulated down to 0 rpm and then starts at about 350 rpm. At 800 rpm, the fan is almost silent, but still offers a good air flow (118.9m 3 /h) paired with a high static pressure (3.17mm/H 2 O). This makes the fan perfect for mounting on radiators of a water cooling system or for the ventilation of a housing. Directly on the frame there are decouplers. The soft foam pads reduce the transmission of vibrations to the housing. Tear-off edges on the fan blades also significantly reduce the background noise. The fan is controlled by a 4-pin PWM connector. The cable is 40 cm long. This allows you to connect the fan to the motherboard or a special controller without further adapter cables or extensions. The digital aRGB LED lighting is controlled via a JST 3-pin connector.
