EK-Quantum Impulse 120 D-RGB is a silence-oriented 120mm computer cooling fan designed and built primarily with the lushest RGB LED illumination in mind. They are not a replacement for other EK fans that maintain a focus on high radiator performance but more of an aesthetic-focused offering that provides silent operation and balanced performance. MagLev Fans EK-Quantum Impulse fans have the VAPO bearing and Magnetic Levitation motor. Addressable RGB LED MagLev Fans EK-Quantum Impulse are 120mm PC radiator and case fans optimized for rich and lush D-RGB effects while maintaining very silent operation across their entire operational range. There is one LED-lit zone around the frame on both sides of the fan, so no matter which fan orientation you require, you'll get the rich illumination of the addressable RGB diffused through a milky white cover. The rotor is also illuminated by its own D-RGB strip for stylish aesthetics while spinning.
