I bought the fan especially for the night, and currently it is again quite hot. Therefore, the fan runs all night.
However, I awake by the sound unfortunately again and again, which is why I turn him pretty quickly.
I have two loud ticking clocks in my room and I live in Frankfurt with train and air transport, etc., so I am not at all fussy about noise concerns.
What works great ear plugs, but you have the also can sleep with earplugs!
But I had got used to it fairly quickly.
(The earplugs I had been catching up because of my neighbors because the walls are very thin and my dear neighbor but gladly throw one or the other party, but I must go to bed early - otherwise I would of course celebrate;))
With Turbo Silence I think the name is somewhat misleading, therefore only four stars, but otherwise the fan is really great!
