Just to post an update, have reached out to both retailers and was given pretty much the same reply; all EU-based stores get them from someone in Germany and they in turn are out of stock. Said German third party is expected to restock early November, so think 'round mid-November for retailers.
So all's fine in the Shire.
and sincere apologies for semi-hijacking your thread
Was just the coincidence of the fan you mention above with the shortage of the 'older' variant, you know? Got me worried, lol
(which sounds a bit.. extreme i guess, granted, but no other fan of this frame type that goes even near 2500RPM; would have sucked if it was no longer an option)
Pride, honour and purity.
