This cooler uses a next-generation pump with automotive-grade components. The 3-phase, 6-slot, 4-pole motor drives coolant efficiently for stable CPU temperatures. The dual-side inlet path directs flow evenly across the micro-fin array. This design helps maintain lower temperatures during extended gaming sessions.

Slim Specifications

Real-Time System Monitoring

The water block features a 3-inch digital display. It shows CPU temperature, frequency, and pump speed in real time. This allows you to check vital stats at a glance without opening case panels. You can install the optional Challenger Driver to adjust mode switching times.

Precision Pump and Flow Dynamics

The pump operates between 1200 and 3200 RPM. It uses a continuous magnetic field for higher energy conversion. Low torque ripple ensures smooth operation, while balanced current load minimises copper loss. These features combine to reduce thermal output during prolonged loads.

Optimised Airflow and Static Pressure

The dual 120mm fans use a Ring-Frame Blade design. This reinforced structure concentrates airflow and generates strong static pressure. It helps push air deep through the radiator fins for efficient heat exchange. The rifle bearings support long-term reliability.

Silent Operation Under Load

The cooler features 0dB Silent Cooling Technology. The fans stop completely during low-load scenarios for absolute silence. This extends the lifespan of the fan bearings and reduces dust buildup inside your system.

Wide Compatibility and Integration

This AIO supports Intel LGA1700 and LGA1851 sockets. It also fits AMD AM5 and AM4 platforms. The 3-pin ARGB header connects directly to ASRock motherboards for Polychrome SYNC. It is also compatible with SignalRGB for unified lighting control across your build.

Box contents

Check before you buy

• Confirm your PC case supports a 240mm radiator (clearance for fans and thickness).
• Verify you have a free 4-pin PWM header for the pump and fans.
• Ensure a free internal 9-pin USB 2.0 header is available for the display.
• Check motherboard clearance around the CPU socket, especially tall RAM modules.

Frequently Asked Questions

Q: Does the 3″ display require software to work?

A: The display shows real-time data out of the box. Optional driver software allows you to adjust mode switching times.

Q: Is the thermal paste pre-applied?

A: Yes, ASRock Therm-X1 thermal grease is pre-applied to the copper cold plate.

Q: Can I use this cooler with a non-ASRock motherboard?

A: Yes, the pump and fans use standard 4-pin PWM connectors. The ARGB works best with ASRock Polychrome but supports standard 3-pin headers.

Q: What is the tubing length?

A: The tubing is 450mm long, made from IIR and EPDM materials for durability.

Q: Does the fan stop completely?

A: Yes, the 0dB Silent Cooling Technology stops the fans under low load for silent operation.
