I just printed a mounting adapter for the mini. Will try out a few things.

The nice thing is, I actually embedded the nuts so mounting/unmounting is very easy.

Hi, can you share your 3d design. I want to try dual fan setup with my Z9 mini. Thanks.

Thank you very much, but one question. Why do you not use screws to connect the plate with the miner?

Actually my initial plan were to make a cowl that could be attached to the back of Z9 mini with screws.
The design I'm using now is more like a prototype to check if things fit. Surprisingly the prototype fitted perfectly with duct-tape, so I just went with it and dropped the screws part.

@kahc
Can you please upload the plans. I was already thinking about buying a old miner and use the plates, but did not found one cheap enough.


Here is the STL file of the 3D model

The Z9 mini cowl looks like this:

these look pretty cool, but too much $$$ for me:

Interesting. Don't like the price point, but the reality is would need to see how effective these actually are.

Hey minermaster team, wanna send me enough to cover 12 Z9 minis and 3 Z9s? I'll happily do a real-life review!

Watching this with interest, the z9 mini is one loud machine so anything to make it quieter is a god send.

Try the S9... Z9 is a dream by comparison. ;-)

Saw your neat setup with the tent in another thread.
Wondering what noise level you get.

It's still loud, to be honest. ~80db outside of the tent. I figured 'sound isolation' would be another project at some point. The tent isolated it enough that they can't be heard throughout the house and no one flips out if I leave the door to that room open.

It's loud enough that i can't use open ear headphones in that room.. and closed ear is questionable. :/

I would probably recommend running an exhaust fan not on the miner itself but rather on the soundbox is better. You can run inline pipe fans and that helps to lower the antminer fan speed and draws out the air from the miner. However you will get added sound from the exhaust inline fan but they are good at pulling out large volume of air and less high pitch more deeper lower pitch noise

So I tried adding a 2nd fan to my Mini (Delta QFR1212GHE) yesterday, but man it was way to loud.  I found that moving the fan about 1 inch away from the backplate reduced the noise a lot, which I think means most of the noise is turbulence.  Even with that, the point of creating a push/pull fan setup is to either cool better at the same noise level or cool the same with reduced noise level.  I'm not really seeing that with these industrial fans.  Removing the backplate completely should help but not sure I want to void my warranty yet.  Also need a way to mount it if the backplate is removed.  Anyone else try this?

Depends on your setup and where you keep the Antminer(s).
The main reasons for me are heat extraction and noise reduction because I live in a one-room apartment running several Antminers in soundproof boxes.

If you attach a hose to Z9 mini without an extra exhaust fan, the intake fan would have to run at max fan speed most of the time to be able to keep the Temp(Chip) under 85.


Ahh, I always forget people try and run industrial mining equipment in places where they really shouldnt lol

Hehehe just a man on the street trying to make a living.
The upside is that they run no more noisier than GPUs now, I can actually sleep without earplugs.

What exactly is the purpose of adding a second fan other than wasting electricity? Even overclocked these things pull a hair over 400 watts and dont put much heat out at all.

I dont get it?

I am curious if you can reduce the speed of the fans when using 2 and keep the temps low? That would reduce the noise level.

Can you please post the temperatures and noise level (dB) here? Would be curious to see how much dual-fans actually help
