Got mine S1 last night and plugged it in straight away. Is it normal for it to be that loud? Also when it starts, the fan seems to be making some clicking noises, they sort of disappear over time as you can hear them anymore over the noise of the fan spinning, is this expected behavior?
are you sure the clicking noise isn't from the the board itself? when it doesn't have internet connection, clicking noise will appear.
100% sure, I had that "no internet connection noise" couple of times and its different. When I start mining, the fan tries to spin itself but somehow fails to do so and only after a minute or so starts to properly spin. Do you reckon the fan might be somehow broken, or is it the power supply to the fan thats causing it?
My two arrived yesterday, one had the same clicking noise you described which was the machine overheating as it's fan was DOA, tried swapping between the two connectors and the two machines to verify.
As soon as I pointed a desktop fan at it, the temps dropped and the clicking stopped.
Asked them to send me a replacement fan with my next order as struggling to find a replacement here in the UK.
