Be Quiet + Silent Eagle SE fans

Now from my understanding the be quiet psu is supposed to keep fans running after the pc is switched off in order to cool everything down - but with these fans the computer turns off and the fans stop. They then being "ticking" for the 3 minutes they are meant to stay running - I presume because there is not enough voltage being supplied.... (I think silent eagles start at 6.5v?). Strangely however the stock lian li fans keep running.

Is it just the case that these silent eagle fans have an unusually high starting voltage or is something actually wrong with them?

From what I can remember as long as you have the fans connected to the PSU outlets they should run on - I can't remember if you need to have the 3pin header from the PSU connected to the mobo - it'd be worth trying this if you haven't. Mine did run on fine, but have since changed to a fan controller anyway so don't use that feature anymore.

The 3pin from the psu is connected to the motherboard header. I've tried the fans connected to the dedicated be quiet fan sockets and via standard molex, but on both of these the fans still stop (3 of them! so surely not faulty). They just rock back and forth trying to start!

As I've said what confuses me is that the stock lian li fans work fine but these supposedly good silent eagle fans don't!

Tis a strange one that - I would think the fans have to be connected to the dedicated fan ports of the PSU - mine were Noctua's and worked fine. What I don't understand though is if the fans are running with the PC switched on, why do they stop and 'twitch' when it's off...? I would have thought they should just continue and that any kind of 'start-up inertia' shouldn't be a factor anyway. Might be worth an email to BeQuiet! support?

edit: just had another thought - when the fans sit there trying to start, if you give a bit of manual assist... do they then spin ok? If so then I would think the PSU could be faulty as they shouldn't be stopping and then trying to restart, they should just run on surely? (I'm sure mine did as your other ones seem to as well)

If the fans are trying to rotate it just sounds like they ain't getting enough juice to get them going.

Like you say as well its very unlikely to be all 3 faulty as well
