Precision VRM Cooling

Validated by Cooler Master Lab, the VRM fan delivers targeted cooling, reducing temperatures by up to 10.2°C across critical components for enhanced performance and stability.

• 28 mmH₂O Air Pressure
• 36 dB(A) Noise Level
• 13°C Temperature Drop

Cooling System - Dual Chamber Design

Patented Design

Our latest patented dual chamber design has been refined for enhanced cooling synergy. The new design increases water pressure and optimises water flow directly to CPU hot spot.

Improved Quality

Fully automated production and assembly of the pump with fully recorded production history.

Tough. Reliable. Built to Endure.

Engineered with PPS and fibreglass, the MasterLiquid Atmos II pump housing delivers industrial-grade strength, exceptional heat resistance, and unmatched durability—designed for builders who demand long-lasting, high-performance cooling. It also passes extreme testing at 70°C for 3,000 hours and 120 °C for 12 hours (Tested by Cooler Master Lab using only the liquid cooling module. Results may vary by system and conditions.), ensuring reliable performance under the harshest conditions.

Pre-Installed SickleFlow Edge ARGB Fan

High RPM fan with low vibration ensure strong cooling with minimal noise, while the dual colour options complement different system aesthetics.

• Speed 2500 RPM
• Noise Level 38.5 dB(A)
• Airflow 190 CFM
• Air Pressure 3.61 mmH₂O

Engineered for Simplicity

Say goodbye to messy cables and hello to a cleaner, faster build. We‘ve seamlessly hidden the wiring inside the tubes—no more exposed pump cables cluttering your setup. Plus, by combining all fan connectors into a single streamlined cable, you get a sleek, minimalist look with less hassle. It’s smarter design that looks as good as it performs.

Ultra-Low Profile Pump Design

The flat design allows installation in cases of different sizes while maintaining strong performance.

Quick and Easy Installation

A quick-mount kit ensures compatibility with mainstream processor sockets and the pre-installed fans simplify setup.

Offset Mounting Brackets for LGA 1851

Due to the varying CPU hotspots across different platforms, there are corresponding mounting bracket solutions tailored for each. We recommend you use the included offset mounting brackets for LGA 1851 (Please check whether your motherboard is compatible with this offset bracket.), which precisely dissipate 4°C of heat from the centre of the CPU.
