Hello, I'm trying to find information on the behavior of the 1x fan that is present in the TL-SG2210MP, part of the JetStream Smart Switch portfolio;

• Is the fan always on, or only under high PoE load?
• What is the typical noise profile like? (dB profile ideally)

For context and comparison, the TL-SG2210P V3.20, which has a lower PoE budget but is otherwise quite similar, is fanless. I'm trying to assess whether the extra PoE headroom weighs up to any fan noise.

Thanks in advance!
