2. Key Features
- 4-Pin PWM Smart Control: Allows for dynamic fan speed adjustment from 800 RPM up to 1600 RPM, based on system temperature, ensuring efficient cooling and reduced noise.
- Advanced ARGB Lighting: Integrates 20 LEDs with a hexagonal RGB ring, offering various lighting modes and supporting 5V3PIN motherboard connectors for software control and full customization.
- Optimized Airflow and Quietness: Features nine specialized wing-shaped blades and a tailored frame designed for maximum quietness, operating under 27 dB(A) even at peak RPM.
- Hydro Dynamic Bearing (HDB): Provides an extended lifespan of 40,000 hours, offering superior durability, longevity, and lower noise compared to traditional hydraulic bearings.
- Anti-Vibration Pads: Equipped with 8 rounded anti-vibration pads to reduce resonance and noise.
- Reverse Fan Blade Design: Unique design allows the fan to be used as an intake fan while showcasing the ARGB lighting and design from the visible side, preventing obstruction by the fan frame.
3. Installation Guide
3.1 Safety Precautions
- Ensure your computer is powered off and unplugged from the wall outlet before installation.
- Discharge any static electricity by touching a grounded metal object before handling components.
- Handle the fan by its frame, avoiding contact with the blades.
3.2 Mounting the Fan
- Identify the desired mounting location within your PC case (e.g., front, top, rear, bottom, or on a radiator).
- Position the Montech RX 120 fan. Due to its reverse blade design, the side with the visible ARGB ring and Montech logo will be the intake side. This allows for clean aesthetics when pulling air into the case.
- Align the fan's screw holes with the mounting points on your case or radiator.
- Secure the fan using the provided screws. Do not overtighten.

3.3 Connecting the Cables
- PWM Connection: Connect the fan's 4-pin PWM cable to an available 4-pin fan header on your motherboard. This allows for speed control.
- ARGB Connection: Connect the fan's 5V3PIN ARGB cable to an available 5V3PIN addressable RGB header on your motherboard. Ensure it is a 5V ARGB header and not a 12V RGB header to prevent damage.
- Route cables neatly to avoid interference with other components and to improve airflow.
4. Operation
4.1 Fan Speed Control (PWM)
The Montech RX 120 fan utilizes PWM (Pulse Width Modulation) technology for precise speed control. Once connected to a 4-pin fan header on your motherboard, the fan speed will automatically adjust based on your system's temperature, as monitored by the motherboard. You can typically fine-tune fan curves and set custom speed profiles through your motherboard's BIOS/UEFI settings or dedicated software provided by your motherboard manufacturer.
4.2 ARGB Lighting Control
The fan's ARGB lighting is controlled via the 5V3PIN addressable RGB header on your motherboard. To customize lighting effects, colors, and synchronization with other ARGB components, use the RGB control software provided by your motherboard manufacturer (e.g., ASUS Aura Sync, MSI Mystic Light Sync, GIGABYTE RGB Fusion, ASRock Polychrome Sync). Ensure the software is up-to-date for the best experience.
5. Maintenance
Regular maintenance helps ensure optimal performance and longevity of your Montech RX 120 fan.
- Cleaning: Periodically clean the fan blades and frame to remove dust buildup. Use compressed air or a soft, dry cloth. Ensure the fan is powered off and unplugged before cleaning.
- Cable Check: Occasionally inspect all cable connections (PWM and ARGB) to ensure they are securely seated and not damaged.
- Environmental Factors: Operate the fan in a clean, dry environment to prevent dust accumulation and moisture damage.
6. Troubleshooting
6.1 Fan Not Spinning
- Verify the 4-pin PWM cable is securely connected to the motherboard fan header.
- Check your motherboard's BIOS/UEFI settings to ensure the fan header is enabled and configured correctly (e.g., not set to 0% duty cycle).
- Ensure the PC power supply is functioning correctly.
6.2 No ARGB Lighting
- Confirm the 5V3PIN ARGB cable is correctly connected to a 5V addressable RGB header on your motherboard. Do NOT connect to a 12V RGB header.
- Check your motherboard's ARGB control software to ensure lighting is enabled and configured.
- Ensure the ARGB header on the motherboard is functioning. Test with another ARGB device if possible.
6.3 Excessive Noise
- Ensure the fan is securely mounted and screws are tightened appropriately.
- Check for any cables or obstructions interfering with the fan blades.
- Adjust fan speed settings in your motherboard's BIOS/UEFI or software to a lower RPM if noise is a concern.
