Air cooler Montech NX400 ARGB, 120 mm fan, FDB, 800–1950 RPM, TDP 270 W, Black

Montech NX400 ARGB is a single-tower air cooler with a 120 mm Fluid Dynamic Bearing (FDB) fan, designed to provide efficient CPU cooling in a compact black housing. The cooler supports fan speeds from 800 to 1950 RPM, a rated TDP of 270 W and delivers up to 2.82 mmH2O static pressure. Its compact dimensions (156 × 74 × 120 mm) make it suitable for most desktop PC builds where space-efficient, effective heat dissipation is required.

Advantages

The NX400 combines a precision-engineered heat sink with a high-performance static-pressure 120 mm FDB fan to balance airflow and pressure for consistent heat transfer. Low-noise operation at typical speeds and a durable bearing design contribute to long-term reliability. The compact single-tower layout and black finish allow easier installation in constrained cases while maintaining cooling performance for mainstream and high-performance CPUs.

Suitable for

• Cooling desktop PC CPUs in mid-tower and compact cases
• Systems requiring a 120 mm single-fan tower cooler
• Builds where a balance of airflow, static pressure and low noise is needed

How to use

Mount the NX400 onto a compatible CPU socket following the motherboard and cooler mounting instructions. Apply a thin, even layer of thermal paste to the CPU heat spreader, align the cooler base and secure the mounting brackets. Connect the fan to the CPU fan header (12 V) and configure fan curves in BIOS or software to match desired noise and cooling balance.

Recommendations

For optimal performance, ensure adequate case airflow (intake and exhaust) and set fan profiles to increase RPM under high CPU load. Verify clearance for RAM modules and large graphics cards before installation.
