CPU air cooler Montech NX400, 120 mm fans, White, dimensions 156×74×120 mm, TDP 270 W

Montech NX400 is a compact single-tower CPU air cooler with two 120 mm white fans and a precision-engineered heatsink. With overall dimensions of 156×74×120 mm and a rated TDP of 270 W, the NX400 is designed to improve thermal performance for desktops used in gaming, productivity and workstation tasks while fitting into compact builds.

Advantages

The cooler combines a dense fin-stack heatsink and a high static-pressure dual-fan configuration to deliver efficient heat transfer in a streamlined housing. Fans operate between 800 and 1950 RPM with a Fluid Dynamic Bearing for reduced noise and longer life, providing a balance of airflow and air pressure suitable for CPU cooling. The white finish integrates with light-coloured or themed builds.

Suitable for

• Gaming desktop PCs requiring effective CPU cooling
• Home and office desktops for productivity and multitasking
• Compact or mid-tower builds where space is limited

How to use

Install the NX400 on a compatible CPU socket following the motherboard and cooler manufacturer instructions. Mount the heatsink securely to the CPU with thermal interface material applied, then attach the dual 120 mm fans to the tower. Connect the fan power cables to the motherboard headers (preferably PWM-controlled CPU_FAN or CPU_OPT) and verify fan operation in BIOS or monitoring software. Ensure there is adequate case airflow for optimal performance.

Recommendations

For best results, use a PWM-controlled header to allow automatic fan speed adjustment and check clearances with RAM modules and case components before installation. Periodically clean dust from the fins and fans to maintain cooling efficiency.
