First of all, the metal fan protection is removed, secondly - it somehow works. I mean temperature drops by ~ 2 degrees and noise drops ~6 dB.
I actually bought it on ebay for another Antminer.

I dont really understand thermodynamics and all but is true that your ambiance temp is below 20c ?, this kind of extension modification not working for tropical climate (ambient above 25c), it only make it hotter (by 2-3 or more in celcius, on s9)
As for the noice reduction, isn it because of projected sound ? The longer the cone will make lower noise but if you measure it on the projection area (in front of the cone) its the same db produced
Anyone tried to put additional exhaust fan on z9 mini ?
It works for me. The temperature is not going up. Today, we have 34C outside (28-29C in the room where this Z9 is located (together with 20 GPUs)
Can you post a picture? I'm in a similar environment.
I did, please look a few posts earlier. Here it is again:
I think he is asking for a picture with it on the miner and hooked up. Would be cool to see.
