The fan most likely DID kick in, it is just very quiet at lower RPMs.
It is possible with NUCs 8-gen and higher, which use much larger fans that run much slower to achive same airflow.
The Nuclus ONE uses a much smaller fan, identical to those used in 4th-7th gen NUCs and those unfortunatley are much louder (due to the fact they spin faster).
@jamie couldn’t hear it - that’s good enough for me.
I have a NUC 8i7BEH which certainly does have a fan that kicks in periodically. I keep it next to my router and nowhere near my listening room. What I find most interesting is that I occasionally hear the NUC fan running when Roon is not in use at all - not even backups. I can only assume that Roon is running some kind of background metadata checks on my library. Perhaps newer NUCs or those with lower CPU power or the Nucleus ONE simply have either much quieter fans or less of a demand that would push the fan to engage.
You should consider the Eversolo DMP A6 streamer/DAC and its HDMI out. It will allow you to connect to your Receiver, costing you just a few 100’s $ than this Nucleus One
… other than it’s more than twice as expensive 
it looks cool.
FWIW, I already have a small Windows NUC as an endpoint, but the HDMI out is flaky, and I’d like a more solid, virtually maintenance-free appliance (like I believe the Nucleus One would be).
Love to have this one, but how can i buy this in Europe ?
You’ll have to wait until it’s shipping to European dealers. No date has been announced as yet, but @jamie has said that it will be happening.
PS I notice that the Nucleus One page in the Roon Labs Store says that the expected release date in the US is 30th June 2024, so I expect that release to the EU will not be before that…
I have the A6, but you will still need a rock or nucleus for the Roon processing. The A6 is a streamer.
I wonder what the backlog is? Release 6/30/2024 but will all orders be filled asap?
I decided to take the Roon plunge from Audirvana. Should I wait for the N1 or install Roon on a laptop?
Install it on a laptop to give it a trial, imho.
If I buy Nucleus One, is any discount on Roon subscription lifetime?
Roon has never done this, but occasionally offers a free subscriptiin with hardware. The Nucleus One is a budget Roon server, and just released, so I’d guess this is unlikely.
Don’t expect a reply from Roon; announcements regarding offers are pinned to the forum, sent in marketing email, or announced in the Roon blog.
I ordered my Nucleus One when it was first announced at that time it was stated it would ship mid May. Now I looked and it showing end of June. Is this for all orders or for newer orders only?
Thanks
I wrote to Roon customer service and they said all orders start shipping at end of June due to “supply chain issues.”
@Robert_Bielecki Thanks for heads up.
Is there any information as to when the new low cost Nucleus will be available in the UK ?
Thanks. Was that specifically about the UK ?
I guess „all orders“ might mean all orders, but don‘t know, it’s the best we have.
Just to note that the beginning of Q3 and the end of June are nearly the same
