However during the easter holidays the whole miner just dropped off the grid. When I came to the site all the PSUs were running, so no major power failure like I saw on the Jupiter I have. Eventually I disconnected all the miners from the controller board and the board started flashing its lights at startup. I was hopeful. But the router never found the controller/Neptune. I suspect it might be the beagle (I have never seen such a scruffy beagle in my life, it looks like it had a lobotomy), but I don't know.
Does anyone have any ideas? If it can be fixed, what fans should I get?
When the controller flashes on boot. Is it 3 short white or 1 longer white? If it's 3, the controller is bad. If none, then more likely bbb. I have been able to use a new bbb on the controller board and it seems to work just fine. I've also picked up some spare controller boards from folks getting rid of jupiter, saturn & mercury units.
I didn't bring the miner with me. I was in kind of in a hurry when I was at the site. I 'll check next time I'm there. BTW I have a Mercury with a fully functional controller board. Any link to how I can get that to play nice with the Neptune cubes?
Just flash the mercury with the neptune firmware, update to latest firmware and you are set. (except merc propbably only has 4 connections instead of 6.
I went down to the site this weekend and picked up the Mercury and the Neptune controller board. Haven't had time to test it though. Anyhew, it's getting warmer and it's not much point in doing the controller board bit without improving the cooling. The 3000rpm Noctua are a bit much to throw into this money pit so I was wondering if anyone had any thoughts about these :

They are roughly 1/3 the price of the Noctuas, which is much more palatable considering the build quality and reliability of the Neptune thus far.
Depends on which Noctuas you want to compare it to. You can get Noctuas with 3000 RPM. So if your comparing to that it does not rank so well. But if it's a 2000 vs 2000 RPM I would think it would be ok. (I disclose I have not used a silver stone tek fan I'm comparing RPM as that is more what I would worry about.)
