The fans on these sticks may not be good.
One now shudders making noise and vibrating the stick.
I pull the two fans and now use external fans all is well in fact better then when I ran with the little fans also not as loud.
I can not find it but someone else said their fan became unbalanced and vibrated.
This happens even though the fan screws are tight and correctly installed,
I have similar issue with fan ( only one of the 3 sticks ordered ).
Time to time starts making really annoying noise ... i also think is's increasing in speed as the noise level is increasing as well (and i can feel unusual vibrations when touch it) but after restarting the miner it's back to normal.
I also tried to tighten/loose the screws but that just change the noise frequency (pitch or what it's called)

... I have quite wide range of fans on hand so will try to find some that fits ... so no big issue.
But have other question.
Wanted to put one of sticks on USB cable and put it between window frames to keep it cold ( i have double windows in my house ) ... miner recognize the stick (green led is on) but won't show any hashrate (just zeros).
Can be the long cable cause of this issue? It's 2 meters long. I tried it with shorter one (1 m) and that works well.
Anyhow, OP you did a great job, thanks for these awesome miniminers.
