2. Setup and Installation
Montech X3 Mesh Case Installation
- Accessing the Interior: The tempered glass side panel is hinged and swings open for easy access to the case interior. Gently pull the fabric loop on the side panel to open it.
- Motherboard and Component Installation: Install your motherboard, CPU, GPU, and other components into the case. Ensure all standoffs are correctly aligned.
- Cable Management: Utilize the cable routing cutouts and tie-down points behind the motherboard tray for clean cable management. Note that some cable routing holes near the PSU shroud may be partially obstructed depending on your power supply and cable thickness.
- Fan Connections: The six pre-installed RGB fans are connected to a fan hub/controller. This hub typically requires a SATA power connection from your power supply. It also provides additional RGB connectors for other compatible components, such as AIO coolers.
- Front Panel I/O Connections: Connect the front panel I/O cables (USB 2.0, USB 3.0, HD Audio, power, reset, LED) to your motherboard. Ensure correct pin alignment for proper functionality.

4. Maintenance
Case Maintenance
- Dust Filters: The Montech X3 Mesh case features removable dust filters, including a magnetic filter on the top panel and a spring-loaded filter on the front. Regularly remove and clean these filters to prevent dust buildup and maintain optimal airflow.
- Tempered Glass Panels: Clean the tempered glass panels with a soft, lint-free cloth and a glass cleaner. Avoid abrasive materials that could scratch the glass.
- Interior Cleaning: Periodically use compressed air to remove dust from internal components and fans.
Power Supply Maintenance
- Fan Cleaning: Ensure the 120mm fan on the power supply remains free of dust and obstructions to allow for proper cooling. Use compressed air to gently clear any dust.
- Ventilation: Ensure adequate ventilation around the power supply unit within the case to prevent overheating.
5. Troubleshooting
- Cable Routing Obstruction: Some users have reported that the two cable routing holes closest to the PSU shroud may be difficult to use due to the power supply's position. Utilize the third, larger routing hole if needed.
- Fan Controller Connectivity: If the fan controller is not functioning as expected or connecting to the motherboard is unclear, refer to your motherboard's manual for specific fan header locations and consult Montech's support resources for detailed wiring diagrams.
- 5V Cable Length: The 5V cable for the fan hub may be short for some motherboard configurations. Plan your cable routing carefully to ensure it reaches the appropriate header.
- Front Panel Fragility: The front panel is a single piece of tempered glass and is not designed to be removed. Exercise caution when handling or transporting the case to prevent damage to the front glass.
