Checking temperatures
There’s no passive cooling here, so because the device heats up quickly, it uses an active heatsink-based cooling system with a small fan to keep the PCB components cool. Overall, it runs quietly and isn’t very noisy. In idle mode without stress, temperatures can reach up to 63°C or higher. When under heavy loads, the PWM fan adjusts its speed to keep temperatures stable, becoming slightly noisier, though in our opinion it remains very quiet.
