The little 45mm fans are normally quite quiet. I had two of our 120's sitting on my desk for a few days when we first got them and never heard them over the rest of the ambient noise.
If the fan is really loud, or making some sort of rhythmic sound, that could be a warning it's going to fail. In that case you may want to contact Astaro support through your usual channel's to request approval to replace the fan. We recently had a fan go on one unit and Astaro authorized me to replace the fan without having to do a full RMA.
