I might not be a native speaker and sometimes my sentencing ends up a bit odd, but I've never been mistaken for a google translator before...

Perhaps do you have some support to your belief?
I can't point out an isolated bunch of reviews supporting this, no. Most alpenföhn reviews I've read have focused on that cooler exclusively and have been in German. (now there's a language that does not auto-translate well into English).
My current stance is mostly a gut feeling from having read a lot of different GPU-cooling reviews. The Shaman was actually my first choice but I didn't find it in stock anywhere, so I began investigating the Alpenföhn instead.
I particularly like the flexibility of being able to completely customize the fan setup (in number and size).
Negative points on the Alpenföhn Peter mostly seem to be about its size and price, not about cooling performance or quietness (which of course comes down to the choice and number of fans used).
The goal for me is to have every single fan in the case customizable and fixed well below 1000RPM at all times. This is like my current setup and that has given me a sonic environment I find acceptable.
I don't have much experience with aftermarket GPU coolers (my current card is a passive GTS 8800) so I don't know if it's possible.

No it is actually a bit smaller. It is not as tall and my biggest concern is diminished space between the PSU and the GPU cooling fans compared to a P180.

Ok good, so the PSU isn't going to be a problem then. Unfortunately the 600-series does not appear to be compatible with the Alpenföhn and they are also quite expensive.

Thanks, I'll look into that.
