MasterLiquid Atmos II Stealth Series Commerce Cloud Storefront Reference Architecture Remove Product? 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.*Tested by Cooler Master Lab. 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. Air Pressure Noise Level Temperature Drop 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 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. Default Cover Metallic Finish Cover VRM Fan Mobius 120P Fans Pressure-optimized fans featuring loop dynamic bearings ensure silent, high-performance airflow even under heavy loads. Thicker Radiator for Better Performance Ultra-low Profile Pump Design Easy Installation 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.
