6. 冷却ソリューション
Due to the increased performance of the Raspberry Pi 5, effective cooling is crucial for stable operation, especially under heavy loads. It is not recommended to use the RPi 5 without a cooling device or with only a heatsink, as this can negatively impact performance. Various cooling solutions are available:
- Pure Copper Heatsink Set: Can be used in conjunction with a cooling fan.
- アクリルケース: Features a removable top cover, includes a PWM cooling fan, and supports camera bracket installation.
- 金属ケース: Made of matte-painted metal and includes a PWM cooling fan.
- Silver ABS Case: Offers a quickly removable design, matte texture, and includes a PWM cooling fan.
- Active Radiator (e.g., Coolbra Pi50): Provides higher heat dissipation efficiency for prolonged full-load operation.
For most users engaged in daily development and learning, a fan-equipped case is recommended. For scenarios requiring the RPi 5 to operate under full load for extended periods, a kit with an active cooler is advisable.
