Antminer Z9 Mini meets Sussuro - from 42 to 30 decibels!

in #mining6 years ago

My Z9Mini(modification-for-home) -- Noctua experiment was very successful but still it irritated me to get the miner even quieter.

After a long search and hundreds of test reports, I came across ALPHACOOL and found the Sussuro fan 120mm -1700rpm Black / Blue Edition.
I ordered them and they arrived already.

Everything is set up and temperatures are monitored for the next 3 days. No problems still full overclocking (750mhz- constant since July2018).
The temperatures are on average 5-8 degrees colder than before in the box.

Volume 36-42 decibels.

That was not enough for me because I still have tubing and rock wool insulation from my MinerBox.
A hose for the front which draws the air and for the back of an exhaust hose with curvature upwards.
For the front:

Everything cut to size and ready to be attached to the miner.
With hoses the volume is constantly 30 decibels.
Termometer shows room temperature above and below the hose heat.
