With exceptional cooling performance, quieter operation, and the Atmos II VRM Fan delivers the perfect blend of performance, customization, and silence. Make it yours with the MasterLiquid Atmos II VRM Fan.

VRM FAN

The VRM fan module cools motherboard hot zones with airflow in six directions. It can reduce temperatures by up to 10.2°C*, to improve both stability and performance.

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.

Patented design

Our latest patented dual chamber design has been refined for enhanced cooling synergy. The new design increases water pressure and optimizes 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 fiberglass, 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*, 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 color options complement different system aesthetics.

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*, which precisely dissipate 4°C of heat from the center of the CPU.
