LCD

The LCD panel provides a real-time display, and the MasterCTRL software supports the creation of GIFs, PNGs, JPGs, scrolling text, and the display of your music or video source.??

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.

*Tested by Cooler Master Lab using only the liquid cooling module. Results may vary by system and 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.**

*Please check whether your motherboard is compatible with this offset bracket.

**Tested by Cooler Master Lab.
