Pure Loop 2 water cooling units offer very high cooling performance and an impressive illumination. Pure Loop 2 FX includes Light Wings PWM high-speed fans with brilliant light effects, and an ARGB- and PWM hub. Pure Loop 2 comes with Pure Wings 3 PWM high-speed fans, that offer a closed loop motor technology. Similar to a cars cruise control, this feature keeps the fan speed at a steady pace, no matter the resistance. Both fans provide high air pressure at low noise. All coolers in this series come with a doubly decoupled pump. This pump is PWM-regulated, making it easy to adjust the water cooling units for silence or performance.
