ASRock Challenger 240 Digital White All in One Liquid CPU Cooler

Forge the Future. Dominate the Game

The ASRock Challenger Digital combines capable CPU cooling with a bold feature set built for modern gaming systems. Compatible with AMD AM5 and AM4, as well as Intel LGA1851 and LGA1700 sockets, it pairs a copper cold plate and 1200–3200 ±10% RPM PWM pump with rifle bearing fans delivering up to 62.6 CFM airflow at 31 dB(A). A 3-inch segment LED display adds real-time system monitoring, while ARGB lighting and durable 450mm IIR + EPDM tubing complete a cooler built around ASRock’s Challenger philosophy of fearless play, bold breakthroughs and relentless evolution.

3" Smart Digital Display

The water block features a vivid 3" digital display with ARGB lighting, providing real-time CPU temperature, frequency and pump speed for at-a-glance system monitoring. The Challenger Driver also allows users to display system information and adjust mode switching time.

3-Phase Pump Motor

The pump uses a precision-engineered structure and automotive-grade components, powered by a 3-phase, 6-slot, 4-pole motor. Its design delivers stronger coolant flow, extended durability and consistent cooling performance for CPU stability.

Next-Gen Cooling System

The pump incorporates a continuous rotating magnetic field for higher energy conversion efficiency, while low torque ripple supports smooth, stable operation. Balanced current distribution minimises copper loss, with reduced core loss improving overall operating efficiency. Lower thermal output helps maintain efficiency during prolonged operation, while the simplified motor architecture removes the need for starting capacitors or coils to improve reliability.

Dual-Side Inlet Cooling Path

A dual-side inlet cooling path shortens the coolant flow distance while distributing coolant evenly across the high-density micro-fin array. Coolant is delivered directly to the CPU hot spot from multiple directions, helping maintain more even temperatures and improving overall thermal efficiency.

Ring-Frame Blade Fans

The Ring-Frame Blade design features a reinforced structure that concentrates airflow for stronger static pressure and deeper radiator penetration. The rifle bearing fans operate from 0–2100 ±10% RPM, delivering up to 62.6 CFM airflow at 31 dB(A) noise. A Zero RPM mode is also supported.

Precision-Machined Copper Cold Plate

The finely crafted copper cold plate provides close surface contact for efficient heat conductivity and long-lasting cooling performance.

ASRock Polychrome Compatible

Connect the 3-pin ARGB header to an ASRock motherboard to enable Polychrome SYNC, with synchronised full-system RGB illumination and control of the ambient AIO lighting. The cooler is also compatible with SignalRGB, which supports control of the LCD display and lighting effects alongside game-reactive effects, macro automation and system monitoring.

Premium Durable Tubing

The tubing uses an IIR+EPDM core designed to resist coolant evaporation and deformation, reinforced with a braided sleeve for added durability and protection.

Pre-Installed Fans & Tube Clips

Radiator fans come pre-installed with neatly routed cables to simplify installation. Multifunctional tube clips secure tubing placement and help maintain a tidy finished build.

ASRock Therm-X1 Thermal Grease

ASRock Therm-X1 thermal grease offers high thermal conductivity for efficient heat transfer, supporting system stability and helping extend CPU lifespan.
