KOTELOTUULETIN 120MM GF120R V2/ARGB PWM 3I1 (V) MONTECH

Montech GF120R V2 ARGB is a set of 120 mm case fans designed for PC cooling. The V2 model features a one-piece seamless frame and a reverse-blade design that allows flexible intake or exhaust configurations while maintaining a consistent visual appearance. Each fan integrates full-addressable RGB across the blade surface and supports PWM for speed control. The fans use hydro dynamic bearings for quieter, longer-lasting operation and are supplied in a 3-in-1 pack suitable for multi-fan installations.

Advantages

The one-piece seamless frame provides a minimalist look and simple replacement or upgrade path. Reverse-blade geometry increases flexibility for airflow orientation without compromising aesthetics. Full ARGB illumination covers the whole blade area for uniform, customizable lighting. PWM support enables precise fan speed control, and hydro dynamic bearings (HDB) improve reliability and reduce noise during prolonged use.

Suitable for

• PC chassis fan mounting
• Radiator cooling in liquid-cooled systems
• Front or rear intake/exhaust configurations

How to use

Mount the fans in standard 120 mm fan locations in the case or on compatible radiators using the included screws. Connect the 4-pin fan connector to a PWM-capable fan header on the motherboard or to a compatible fan controller for speed control. Connect the 3-pin ARGB LED connector to an addressable RGB header or to the included RGB controller to enable lighting control. Configure PWM curves and ARGB effects through the motherboard software or the supplied controller according to your cooling and lighting preferences.

Recommendations

For optimal cooling and balanced airflow, arrange intake and exhaust fans to create a consistent front-to-back or bottom-to-top airflow path. Use PWM control to reduce fan speed and noise during low loads, and ensure ARGB connections match the motherboard header voltage and pinout before powering the system.
