Why this product
3.4-inch LCD display with real-time stats
The IPS LCD shows system metrics and custom visuals in 480 x 480 resolution at 60 FPS. Connect via USB Type-C to your motherboard for instant access to temperature, clock speed and animations.
Aerospace-grade LCP fan blades
Crafted from Liquid Crystal Polymer, the blades hold their geometry under extreme RPM and thermal stress, ensuring stable rotation and long service life.
0dB silent mode under low load
The radiator fans stop completely when demand is light, eliminating noise and extending bearing lifespan during quiet operation.
3-phase 6-slot pump with dual-inlet path
The precision motor runs 1200–3100 RPM and delivers stronger flow and extended durability for stable CPU power delivery and cooling.
RGB sync with Polychrome and SignalRGB
Connect the ARGB header to an ASRock motherboard for full-system synchronized lighting, or use SignalRGB software for game-reactive effects and macro automation.
6-year cooler and 2-year LCD warranty
Industrial components and dual-ball bearings back the promise of long-lasting reliability.
