Airflow and Cooling
Modern Airflow Concepts (2025)
Positive Pressure Setup: - More intake fans than exhaust - Reduces dust accumulation - Maintains consistent airflow - Recommended: 3x intake front, 1x exhaust rear
Dual-Chamber Design: - Separates hot components (GPU, CPU) from PSU and drives - Improved thermal performance - Cleaner cable management - Examples: NZXT H9 series, Lian Li O11 Dynamic
Mesh Front Panels: - Direct airflow to components - 20-30% better cooling than solid fronts - Essential for high-performance builds - Look for: Large mesh area, removable dust filters
Fan Configuration Guidelines
Budget Builds (RTX 5060/5060 Ti): - Minimum: 2x 120mm intake (front), 1x 120mm exhaust (rear) - Case fans included: Usually sufficient - Upgrade priority: Add top exhaust if temperatures high
Mid-Range Builds (RTX 5070/5070 Ti): - Recommended: 3x 120mm intake (front), 1-2x exhaust (rear/top) - Consider: 140mm fans for better airflow/noise ratio - AIO placement: Top mount for CPU, front mount if GPU runs hot
High-End Builds (RTX 5080/5090): - Minimum: 3x 140mm intake, 2-3x exhaust - AIO cooling: Essential for CPU, consider GPU AIO - Custom curves: Adjust fan speeds based on component temperatures

Building Tips
Pre-Build Planning
Case Preparation: 1. Remove panels: Side panels, front panel if removable 2. Install standoffs: Match motherboard form factor 3. Test fit components: Check clearances before assembly 4. Plan cable routes: Identify paths for major cables
Tool Requirements: - Phillips head screwdriver (magnetic tip recommended) - Anti-static wrist strap (optional but recommended) - Zip ties or velcro straps for cable management - Thermal paste (if not included with cooler)
Assembly Order
Step 1: PSU Installation - Install PSU with fan facing down (if case has bottom ventilation) - Connect modular cables before final positioning - Route 24-pin and CPU power cables early
Step 2: Motherboard Preparation - Install CPU, RAM, and M.2 SSDs outside case - Mount I/O shield in case - Install motherboard with all standoffs aligned
Step 3: Storage and Expansion - Install SATA drives in designated bays - Mount additional M.2 drives if available - Install expansion cards (GPU last)
Step 4: Cooling Installation - Mount case fans in optimal positions - Install CPU cooler (air or AIO) - Connect all fan headers and RGB if applicable
Step 5: Final Connections - Connect all power cables - Route and secure all cables - Connect front panel connectors - Install graphics card last
Cable Management Best Practices
Behind Motherboard Tray: - Route 24-pin ATX cable along edge - Bundle SATA and peripheral cables together - Use tie-down points to secure cables - Leave some slack for component movement
Visible Areas: - Keep only necessary cables visible - Use cable combs for multi-cable connectors - Route cables along case edges - Hide cable connections behind components when possible
RGB and Fan Cables: - Plan RGB controller placement early - Group RGB and fan cables separately - Use case RGB hubs if available - Route RGB cables away from high-heat areas
Common Mistakes to Avoid
Clearance Issues: - Always verify GPU length vs case clearance - Check CPU cooler height before purchase - Confirm PSU length with modular connectors - Test RAM clearance with large CPU coolers
Airflow Problems: - Don't install all fans as exhaust - Avoid blocking mesh panels with components - Don't forget dust filters on intake fans - Plan positive pressure (more intake than exhaust)
Cable Management Errors: - Don't force panels closed over thick cables - Avoid routing cables near hot components - Don't bundle power and signal cables together - Test all connections before final cable routing
Post-Build Checklist
Power On Test: 1. Connect only essential components initially 2. Test power button functionality 3. Verify POST (BIOS screen) 4. Check all fans are spinning
Temperature Monitoring: 1. Install monitoring software (HWiNFO64) 2. Run initial temperature checks 3. Stress test CPU and GPU separately 4. Monitor temperatures under full load
Final Assembly: 1. Install all drives and peripherals 2. Complete cable management 3. Install side panels 4. Test all ports and functionality
Maintenance Schedule
Monthly: - Visual dust filter inspection - Check system temperatures - Verify all fans functioning
Quarterly: - Clean dust filters - Compressed air cleaning - Cable management review
Annually: - Deep clean all components - Replace thermal paste if temperatures rising - Check for any loose connections - Update case firmware if applicable
