6. Cooling Solutions

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.
• એક્રેલિક કેસ: Features a removable top cover, includes a PWM cooling fan, and supports camera bracket installation.
• મેટલ કેસ: 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.
