Power quieter fan

Acquisition reason: I live on the 5th floor on the sunny side of my building with a huge window front and as a student I prefer to learn at home, so I would come in particular this summer a sweat.
Were it not for this great fan:
Pro:
-er is quiet: Who lives even close to the city and its window has to "tilt" and thereby slight ambient noise is accustomed to taking this fan is no longer true after a few minutes.
-er is persistent: It runs now with me a few months, in recent weeks, up to 12 hours a day almost without interruption. No signs of wear or the like.
-he has Power: I put him forward to the lightest level (the first of three possible) to the other side of the room (3m away). Get closer or more you really only need if you want to catch a cold or at 30 ° +. Nevertheless, for me a pro, because I need no lighter step, and the stronger steps you can to midday heat from and to use already.
Design, weight: I think it looks good (pretty simple, kept black) and it is very easy, so you can stand it without problems elsewhere

Contraindications:
-no automatic swiveling function. That's the only thing you could still get to the bonus.

Conclusion: Silent Power fan for hot days
