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:
For the back:
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.
Buddha ensures good mining.
Happy mining to all of you and believe in Crypto, share your knowledge and let's change something.
Thank you
