The Raspberry Pi 5 can handle typical client – side workloads without an enclosure and without active cooling. If users wish to use the circuit board without an enclosure to withstand continuous heavy loads without experiencing throttling, they can choose to install an active cooler.
Under typical ambient temperatures and the most severe load conditions, both the chassis and the active cooler can keep the Raspberry Pi 5 below the thermal throttling point.
Active coolers have superior heat dissipation performance and are particularly suitable for overclocking enthusiasts.
