We have received customer feedback indicating that TV boxes can become hot during use. Under normal operation, most TV boxes do not include a cooling fan and rely only on a small heat sink. During extended playback, CPU temperature may rise significantly, potentially reaching 60-70C, which can lead to video freezing, system instability, or shutdowns, and may shorten the device's lifespan. Using a cooling fan with your TV box helps maintain optimal operating temperature. Our tests show that with the cooling fan, the internal CPU temperature remains consistently between 40C and 50C even after continuous operation for a full day. This helps prevent freezing, system crashes, and overheating, contributing to improved performance and extended device longevity.
