## Long description

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
