Good fan and helpful

So with all due nagging, I have to say this Lüftsystem works flawlessly and makes plus sense.
The power consumption is not as high as it is claimed, for there the Lüftstärkenregler and in addition, the fan can also be switched off, ie when the PS3 is loud then you can anschmeissen the fan and within 10 minutes is the PS3 again quietly (own experience) ,
If the PS3 not be silent then you can switch off and on again briefly with running fan, run quickly for a go on.
On the subject of dust is only one to say whether external cooling fan or internal fan dust we pulled either way and when I read "dust comes to where he does not hinsoll" the question is where should he go?
My conclusion for the fan system: Mercilessly awesome!
