Next-Gen Cooling System

Next-Gen Cooling Pump

Precision-engineered structure and automotive-grade components, powered by a 3-phase, 6-slot, 4-pole motor for stronger flow, extended durability, and peak cooling performance for unwavering CPU stability.

Continuous Magnetic Field: - Continuous rotating magnetic field for higher energy conversion efficiency.
Low Torque Ripple: - Low torque ripple ensures smooth and stable operation.
Balanced Current Load: - Balanced current distribution minimizes copper loss.
Reduced Core Loss: - Reduced core loss improves overall operating efficiency.
Lower Thermal Output: - Lower thermal output maintains efficiency during prolonged operation.
Simplified Motor Architecture: - No starting capacitors or coils required, improving reliability.

Dual-Side Inlet Cooling Path
The dual-side inlet cooling path design shortens coolant flow distance while ensuring balanced distribution across the high-density micro-fin array. By delivering coolant directly to the CPU hot spot from multiple directions, the design helps keep temperatures more even and improves overall thermal efficiency.

Optimized Thermal Fan Design

Targeted Airflow Technology
Integrated ventilation and air-guide design channel airflow directly to heat-critical zones for maximum cooling efficiency.

Striped Ring Fan
The Striped Ring fan design features reinforced blades engineered to optimize airflow across both the VRM module and the radiator, driving high-volume intake to keep power delivery components cool and stable, while generating strong lateral airflow for deep fin penetration and maximum radiator cooling efficiency.

Aerospace-grade LCP Fan

LCP Blade Structure
Crafted from aerospace-grade LCP (Liquid Crystal Polymer), the blades maintain flawless geometry under extreme RPM and thermal stress — ensuring enduring precision, durability, and performance stability.

Copper Alloy Bearing Hub
Crafted for superior concentricity, ensuring stable and effortless rotation under extreme conditions.

Dual-ball Bearing
The dual-bearing mechanism delivers consistent, long-lasting performance even under continuous high-temperature operation.

0dB Silent Cooling Technology
Fan stops completely under low load for absolute silence and extended lifespan.

POLYCHROME RGB
Simply connect the 3-pin ARGB header to an ASRock motherboard to unlock Polychrome SYNC support, experience perfectly synchronized, full-system RGB illumination with seamless control.

SignalRGB
SignalRGB unifies your RGB devices, offering seamless customization, game-reactive effects, macro automation, and system monitoring. ASRock AIO Liquid Coolers have passed comprehensive SignalRGB compatibility testing, ensuring reliable control of the LCD display and lighting effects through the SignalRGB software.

Hidden Connection Design

Clean Build Aesthetic
Cables remain hidden between fans, with only a single cable required to connect to the motherboard for a cleaner build.

ASRock Therm-X1 Thermal Grease
High thermal conductivity enables efficient heat transfer, enhancing system stability and extending CPU lifespan.
