Cooling Strategy
Effective cooling extends component lifespan and maintains peak performance:
- Air Cooling: Sufficient for most builds, quieter operation, lower maintenance
- 240mm AIO: Better aesthetics, good performance for mid-range CPUs
- 360mm AIO: Necessary for high-end CPUs under sustained loads
- Custom Loops: Maximum performance and aesthetics, requires maintenance
Essential Tools and Setup
Having the right tools makes building a PC safer, faster, and more enjoyable:
Phillips head #1 and #2, magnetic tips prevent dropped screws
Protects components from electrostatic discharge damage
High-quality thermal compound for optimal heat transfer
Velcro straps and zip ties for clean cable management
Assembly Best Practices
Follow these steps for a smooth building experience:
Pre-Build Preparation
- Workspace Setup: Clean, well-lit area with anti-static precautions
- Component Inspection: Verify all parts are present and undamaged
- Documentation: Have motherboard manual and component guides ready
- Test Components: POST test outside the case first
Assembly Order
- Install CPU and RAM on motherboard outside the case
- Install motherboard standoffs in case
- Mount power supply with fan facing down if case allows
- Install motherboard I/O shield and motherboard
- Connect power cables before installing GPU
- Install storage drives and connect SATA/NVMe
- Install GPU last to avoid interference
- Connect front panel headers carefully using motherboard diagram
Final Checklist Before First Boot
