Fan noise without being in battery mode

Hi,

I already have my Elite 100 V2 connected to several devices in my house. A router that is powered directly from the front USB DC port and others from the AC output. Everything is fine so far.
The device is connected to the electrical grid and the average consumption of the devices does not exceed 100-200W on average. But from time to time I hear the fan activate and I don’t know why if it is connected to the grid and the battery is at 100%.
The room temperature is around 23ºC.

Thank you

On the AC500 the fan runs during charging and/or discharging. Although I’m not familiar with the Elite model my guess is that it’s normal. A sensor determines when the electronics need cooling.
