Key item features

  • Vivid Display: Features a 3.5-inch full-color LCD screen on the pump block for displaying live system statistics, custom artwork, animated GIFs, and pre-designed animations from the ROG gallery.
  • Enhanced Cooling: Equipped with an 8th Gen Asetek pump with a 3-phase motor and a 32% larger cold plate for improved CPU temperature management, alongside a thicker 279.5 x 120 x 30 mm radiator.
  • Optimized Airflow: Includes two famously quiet 120mm Noctua industrialPPC PWM fans and an embedded Axial-tech fan that reduces motherboard VRM temperatures by up to 35 Celsius.
  • Improved Tubing: The sleeved rubber tubing has an enlarged inner diameter from 5 mm to 7 mm, reducing flow resistance, and measures 400 mm for extensive compatibility.
  • Software Integration: Offers software for controlling pump and embedded fan speeds, and includes a one-year subscription to AIDA64 Extreme for live system data display on the LCD.
