As I can't reach warranty@minereu.com (overzealous antispam filter that bounces my emails), here is the message I sent 2 days ago to warranty@minereu.com, posted on the Google group used for support and retried sending to warranty@minereu.com a couple of minutes ago (with another bounce) :

Hi,

out of the 3 miners in order #1664, one just died.
The Raspberry is still working fine, but it can't reach the 2 blades at all.
The main fan isn't spinning on startup either. I opened the top panel of
the a2mini to check for any obvious problem but couldn't find any (no
burn trace or physical damage visible).

It seems the problem comes from the controller board : the main fan and
the 2 blades are connected to it and stopped working at the same time
while the Raspberry is working fine.

Is it possible to get a replacement for the controller board ? Better :
can I purchase an additional one on top of the replacement one to avoid
too much downtime in the future if it happens again ?

Best regards,

(sig removed to avoid privacy problems)

How can I proceed to reach minereu.com support and deal with this problem?

You could get the blades working in the mean time by plugging them in (including the fan) the controller of one of your other working miners. It should work then, you then just have a 60 MH/s miner.
Than you know for sure as well it is the controller.

How to contact them otherwise then mail or PM I don't know

Yes I realized that the controller had free ports and I thought about connecting the blades and the fans to another controller (I didn't take the miner apart yet so I didn't find a free port for a second fan though).
What worries me is that I would connect the two PSUs together at least by their ground. They are clearly cheap PSUs and if there's any defect where the grounds aren't properly grounded there will be leakage current and this could fry something. Unless minereu.com tells me it's fine to use the miners like this while waiting for a replacement, I'll probably remove both PSUs and use a common standard PC 80+ Gold PSU instead to avoid any problem, this is far more invasive and I would like to avoid it.

Will try a PM too, thanks for the suggestion.
