3. Setup and Installation
This section provides general guidelines for setting up your Aerocool Cronus Mid Tower Case. For detailed component-specific instructions, please refer to the manuals provided with your motherboard, power supply, and other hardware.
3.1. Preparing the Case
- Unpack the case carefully and remove all packaging materials.
- Place the case on a stable, flat surface.
- Remove the tempered glass side panel by unscrewing the thumb screws and gently pulling it away. Set it aside on a soft, non-abrasive surface to prevent scratches.
- Remove the opposite side panel to access the cable management area.
3.2. Component Installation
- Motherboard Installation: Install the necessary standoffs for your motherboard form factor (E-ATX, ATX, Micro-ATX, Mini-ITX). Carefully place the motherboard into the case, aligning it with the standoffs, and secure it with screws.
- Power Supply Installation: Mount the power supply unit (PSU) in the designated bottom compartment. Secure it with screws from the rear of the case.
- Storage Drive Installation: Install 2.5" SSDs and 3.5" HDDs into their respective drive bays. Utilize the tool-less mechanisms where available or secure with screws.
- Graphics Card (GPU) Installation: Insert your graphics card into the appropriate PCIe slot on the motherboard. For vertical GPU installation, use the additional expansion slots and the included GPU bracket. Secure the GPU firmly.
- Cooling System Installation: Install any additional fans or liquid cooling radiators as desired. The case supports various fan configurations and radiator sizes.
3.3. Cable Management
Utilize the cable grommets and passthrough tubes located behind the motherboard tray to route power cables and data cables neatly. This improves airflow and gives your build a cleaner appearance.
4. Operating Instructions
4.1. Powering On
After all components are installed and cables are connected, ensure the power supply switch is in the 'ON' position. Press the power button on the top I/O panel of the case to start your system.
4.2. ARGB Lighting Control
The Aerocool Cronus case features an X-shaped RGB LED front panel and an ARGB rear fan, controlled via a 6-port PC fan hub. Lighting can be managed in two primary ways:
- LED Control Button: Use the dedicated LED control button on the top I/O panel to cycle through various pre-set lighting effects and colors.
- Motherboard Software: Connect the ARGB hub to a compatible ARGB header on your motherboard (e.g., 5V 3-pin ARGB header). This allows you to synchronize lighting effects across all compatible components using your motherboard's RGB software (e.g., ASUS Aura Sync, MSI Mystic Light Sync, Gigabyte RGB Fusion, ASRock Polychrome Sync). Refer to your motherboard manual for specific software instructions.
5. Maintenance and Care
Regular maintenance helps ensure optimal performance and longevity of your PC case.
- Dust Cleaning: Periodically clean dust filters (if present) and internal components using compressed air. Ensure the system is powered off and unplugged before cleaning.
- Exterior Cleaning: Wipe the exterior surfaces, including the tempered glass panel, with a soft, damp cloth. Avoid abrasive cleaners or solvents that may damage the finish.
- Cable Check: Occasionally check internal cable connections to ensure they are secure and not obstructing airflow.
