3.5″ LCD Display with Custom Animation

The expansive 3.5-inch LCD screen built into the pump block offers real-time system monitoring of clock frequencies, voltages, temperatures, and fan speeds. Users can display custom GIFs, upload personal artwork, or choose from ROG’s pre-designed animations. The doubled internal memory supports clearer animations and longer video playback for personalised system aesthetics.

Magnetic ARGB Fan System

Three ROG 120 mm ARGB fans feature magnetic connectors that snap together, transmitting both power and control signals through a single cable. This daisy-chainable design simplifies installation and dramatically improves cable management. The fans utilise magnetic levitation bearings for reduced noise and enhanced longevity.

Enhanced Cooling Performance

The 8th Gen Asetek pump features a 3-phase motor delivering higher flow rates with quieter operation. A 32% larger cold plate maximises contact area with modern processors, while the 279.5 x 120 x 30 mm radiator provides 3 mm of additional thickness compared to previous generations. Enhanced 7 mm inner diameter tubing reduces flow resistance for improved thermal efficiency.

Embedded VRM Cooling Fan

An integrated Axial-tech fan sits within the pump block, directing airflow across motherboard VRM components. This dedicated cooling solution reduces VRM temperatures by up to 35°C, ensuring stable power delivery during intense gaming sessions or heavy workloads. The fan operates in conjunction with the main radiator fans for comprehensive system cooling.
