Strato Pi Fan

Sfera Labs Strato Pi Fan is used to enhance the Raspberry Pi Model B version 2, 3, and 4 with a high-speed, temperature-controlled fan. It expands the operating temperature range of the Raspberry Pi. It also reduces or delays CPU throttling under heavy CPU load. NOTE: Raspberry Pi not included.
