Liquid cooling kit Cooler Master MasterLiquid Atmos II 360 VRM Fan White 120 mm, 322.8 m³/h, LDB bearing

Cooler Master MasterLiquid Atmos II 360 VRM Fan in white is a 12 cm processor liquid cooling kit designed to improve CPU and motherboard VRM thermal performance. The low-profile pump and pre-installed SickleFlow Edge ARGB fans allow installation in compact cases while delivering targeted cooling. The kit includes a VRM fan module that directs airflow in six directions to cool motherboard hot zones and a patented dual-chamber pump that increases water pressure and optimizes flow to CPU hotspots. Cryofuze thermal paste and tube clips are included, and the cooler is validated in Cooler Master Lab testing for targeted VRM temperature reductions.

Advantages

The Atmos II VRM Fan provides precision VRM cooling that can reduce critical component temperatures by up to 10.2°C in Cooler Master Lab tests. Its patented dual chamber pump design improves water pressure and flow to the CPU hot spot, while the ultra-low profile pump enables compatibility with smaller cases. The SickleFlow Edge ARGB fans run at high RPM with low vibration for effective cooling and minimal noise. The pump housing is made of PPS with fiberglass for enhanced strength and heat resistance and is produced with a fully automated process with recorded production history.

Suitable for

• Enthusiast and mainstream desktop builds requiring improved VRM and CPU cooling
• Small form factor cases where a low-profile pump is needed
• Systems using supported sockets (LGA 1150/1151/1155/1156/1200/1700/1851, AM4, AM5)

How to use

Install the MasterLiquid Atmos II 360 following the quick-mount kit instructions for your motherboard socket. Fit the radiator and fans into your case, attach the ultra-low profile pump over the CPU, and connect the pre-installed fan and pump cables to the appropriate headers for power and PWM/ARGB control. If your system uses LGA 1851, use the included offset mounting brackets to align cooling over the CPU hotspot. Apply the included Cryofuze thermal paste between the CPU and pump cold plate before final mounting.

Recommendations

Check motherboard compatibility before installation, especially for the LGA 1851 offset bracket. Results for temperature reduction were obtained in Cooler Master Lab testing and may vary by system configuration and operating conditions.
