Well it's only been a few days since the last fan rant thread, will it ever end?
FAS installs the fan it feels best cools the unit and is reliable, FULLY REALIZING it is not the quietest option. G66 chooses to change out the fans on the units they ship, but I believe they do so at their own risk.
Your US shipped unit will come with the FAS fan, including its noise issues, get use to it.
So, the European distributor is modifying the unit in a way not recommended by Fractal and at their own risk?
If it didn't provide enough cooling I strongly doubt they would have put it in there.
I'm not in Europe so it doesn't affect me, but the statement from G66 doesn't specifically mention the Axe-FX II - it could be they only upgraded the Standard and Ultra.
