Once again moved to a new apartment and thought why my setup does not make even quieter than currently. (15 to 18 Decibel)
SilentX has served me well so far, but I wanted more.
So off in the basement to dig up the box again. All newly taped and insulated inside.
Pipes adapted and rock wool cut to later strip the pipes inside and outside in addition.
Use z9 mini. Adjust tubes and if necessary attach with tape.
Mount the power supply and check cable connections.
Start the engines!
Start the machine and check with the green LED if the mining starts.
Now we have 12-14 Decibel.
Happy Mining at the living Room dear All, thanks for the support!
