I have "emulate" a total of 3 Turmventis. In the office we have a very good and expensive. Very, very quiet part of the home and a no-name product, but unfortunately this is creaking rotate slightly when. The ventilation, however, is consistently significantly quieter than in this Venti. Level 1 is still okay, but Level 2 and Level 3 are let run too loudly for the part when watching TV. I wonder if I we grab the part in the crate.
The ventilation, however, is useful
