Setting Up the S19J Pro

Our s19 jpro has been sitting idle for several weeks now because it is too loud and generates too much heat for the garage. We tested a soundproofing box from Cryptology Consulting, which worked well, but could be improved with a proper intake and exhaust setup.

Today, we are installing our Bitmain S19J Pro in our crypto mining shed. Our shed has an 8-inch intake duct, an AC Infinity air filter box, and an 8-inch exhaust duct. Our goal is to test the temperature and sound levels before and after installing the soundproofing box to see the difference it makes.

Baseline Sound Levels

Before installing the miner, we took baseline sound level measurements at three areas: our neighbor’s house, the exhaust side of the shed, and inside the shed. At our neighbor’s house, the sound level was 61 decibels (dB). On the exhaust side of the shed, it was 75 dB, and inside the shed, it was 79 dB. These measurements are important as we want to minimize the noise our mining operation generates for our neighbors.

Before Installing the Soundproofing Box

When we installed the S19J Pro miner in the shed without the soundproofing box, we recorded the following sound levels at the same three areas:

– Neighbor’s house: 63 dB
– Exhaust side of the shed: 74 dB
– Inside the shed: 83 dB
These results show that the miner did not significantly increase the sound levels except for inside the shed, though there was a noticeable high-pitched whine noise coming from the ASIC’s fans that was not captured in the sound level measurements.

With the Soundproofing Box Installed

Next, we installed the S19J Pro inside the soundproofing box, which had dedicated intake and exhaust connections to ensure proper airflow. The sound levels were measured again at the three areas:

– Neighbor’s house: 63 dB
– Exhaust side of the shed: 74 dB
– Inside the shed: 74 dB
While the sound levels at the neighbor’s house and the exhaust side of the shed remained unchanged, there was a significant reduction in sound levels inside the shed. Moreover, the high-pitched whine noise was almost completely eliminated.

However, despite the improved sound levels, the miner’s temperature inside the soundproofing box increased to problematic levels. The inlet temperature was around 84-85 Celsius, and the outlet temperature was 88-90 Celsius. The increased temperature resulted in the miner stopping its mining operations due to overheating.

Potential Solutions and Next Steps

Based on the results of our testing, the soundproofing box does provide a significant reduction in sound levels, particularly inside the shed. However, the airflow restriction caused by the box leads to overheating issues for the S19J Pro miner.

In order to improve airflow and maintain acceptable temperatures for the miner while keeping sound levels down, we are going to implement a customized solution by adding AC Infinity 8-inch inline fans to the intake and exhaust sides of the ASIC. This setup will push air through the miner more efficiently and avoid overheating problems during mining operations.


Overall, our experience installing the S19J Pro into our crypto mining shed has been a learning process, with challenges in achieving both quiet operations and efficient cooling for the miner. Although the Cryptology Consulting soundproofing box did provide a reduction in sound levels, it needs to be modified for better airflow to prevent overheating. By adding AC Infinity inline fans to the system, we hope to achieve the perfect balance between quiet mining and proper cooling for our ASIC miner. Stay tuned for updates on our future progress with this exciting project.

  1. Thanks for the review Hobbyist! And for those watching, every box comes with two shroud to connect to ducting/fans. Also recommended to use the fans for s19 type ASICS unless you are in an area with open air flow.

  2. Take a recording, take the Fourier transform of the sound signal, it will show you the break down of the different frequencies (pitches) found in the sound signal. that will allow you to objectively show if the box decreases the high frequency signals. If you want help you can send me sound recordings, I can send back the frequency distributions

  3. It's generally accepted that a 10db decrease will HALVE the sound volume. A 4db decrease is about 40% quieter give or take. a 4 db INCREASE makes it 40% louder. But it sounds like the sound proofing box is focused on reducing the annoying high end whining frequency. You need something like a spectrum analyzer to see what's happening with that high end frequency. But your ears are hearing the reduction there. My guess is that the sound proof box is designed to reduce the high frequency whine. If you had a room full of ASIC's, in those boxes, it would make a huge difference.

  4. I was going to recommend Space MIner, but you've already discovered him. Replacing the miner fans with an inline fan seems to be the way to go for us mining in residential or space/sound-limited areas.

  5. (1) Detach & toss those four 6000RPM s19 fans. (2) Toss that MERV Filter and just put the miner in the AC Infinity box. The box already has 8" intake/exhaust. (3) Attach an AC Infinity 8" Fan on the intake & exhaust side. Those will push/pull 735 cfm each, when compared to the high pitch 6000 RPM fan which only pull 135 cfm each. (4) Your exhaust duct is acting like a shotgun going right through the shed and blasting the noise out like a cannon. You need some curves in the ducting, or at least move the exhaust port to shoot up out the roof or down under the shed. I think down would be better as the noise would hit the rocks and disperse due to the various rock angles. The shed itself will also act as dampening to the noise. Not to mention the heat blowing underneath would help keep it dry under the shed to prevent wood rot.

  6. Install Wool soundproofing insulation (Home Depot) on the wall facing the neighbors, stops all the noise, which will cover the GPU noise in the future as well.

    Also move the fan "line of sight" to the intake and exhaust vents, Sound does not travel around Coners, and old HVAC trick. Does not have to be 90 degrees just pull the duct and miner more into the room or up on a raised platform should do the trick. If you can "see" the fan you can hear the fan.

    The ASIC fans are designed for no restriction applications. As soon as you add duct you must add fans to compensate for the duct, vent and filter loss and add a fan to overcome the "dirty filter" calculations. Use the AC Infinity temperature probe in the duct and close to the miner's leaving air so the fans can spin up or down as required. After some testing it should balance out keeping the safety of the ASIC fans in place. I do not like bypassing the fans without other safety measures in place and costing me a hash board or a whole miner. YIKES

    And you do NOT need a MERV 14 HEPA Filter, that's for house fresh air exchange filtration of minute particles. The fan curve for that would be a really BIG high static fan to equal a reasonable CFM/LPM calculation as it will fill up in a super short period of time, say weekly filter changes, and that's a huge cost.

    These things run in open warehouses, dirt and all and they do great – You are not breathing this air you just want to keep out the big stuff.

  7. Gotta use 10" ducting and never less than 8" but been down this route enough to know ya can't restrict airflow in or out. 6" restricts too much. 10" is the sweet spot

  8. I don't have an ASIC, but what happens if you add a 8" long tube between the intake fan and the miner using long threaded rod?

  9. Air flow – Sound !!!
    Sound waves are created when air molecules are set into motion and their energy is transmitted to adjacent air molecules. When a rock hits water, waves spread in circles. In exactly the same way a sound source creates waves or pressure variations in the air. These pressure variations are perceived by the ear as sound.
    When you try to make your ASIC to give less sound. What you end up with is Motor Highway traffic jam basically.
    More noise means BETTER air flow.
    So when you put fans before and after the ASIC + a filter. You will reduce some noise. But you loose much more airflow.
    As an ex. 70db is 10.000.000 power ratio but 80db is 100.000.000 power ratio.
    The decibel (symbol: dB) is a relative unit of measurement equal to one tenth of a bel (B). It expresses the ratio of two values of a power or root-power quantity on a logarithmic scale. Two signals whose levels differ by one decibel have a power ratio of 10 1/10

    Take a shed and make hot and cold side. Intake need fans to delivered air. If you also have some holes to let some off the air out. You create airflow and fans will deliver more fresh air. Not a stagnate air. Air + flow is king. Same principle on exhaust side.

    Now you have fresh air with god flow on intake. Miner will transfer heat from one side to the other side. Exhaust side will now remove the hot.
    Basically a bitcoin container 🙂

    Insulating your shed with thick walls will help remove some sound because air don't move true walls so good.
    But intake and exhaust will always carry sound.

  10. Measure different HZ and you will se why its so shitty to have ASIC. And you need to buy the right sound dampening based on HZ. And 77 to 80 is a big different in sound strenght

  11. Have you looked at using something like a centrifugal blower to generate the air flow? As you've got a sealed system for the airflow, you could drop the small noisy fans off the miner and replace them with one big centrifugal blower with its inlet connected to the box outlet, pulling air through the system and then blow it up to the sky, that would eliminate the high pitch loud noise.

    For example, a quick ebay search I find an OBR200M which will do 1800m3/h (~1000cfm) – I think that's enough for 2 asics, noise is ~65 db (it won't be high pitched), as the fan is larger it only needs a lower rpm (1440rpm – vs probably 10k+ for those noisy little 120mm – they need to run fast to generate the airflow because they're small, and hence they become noisy with a high pitch note). This style fans are very common in industry – such as for kitchen extraction, chemical fume cupboards, dust extraction etc, they're commonly used to draw air through a system, rather than blowing, so don't let the name confuse it.

    You would however need to make sure the air flowed over the heatsinks in the miner, and not just around the outside, but that should be fairly easy in that box.

  12. bitmain makes these devices with several constraints in mind – arriving at a balance that meets the needs of those constraints most appropriately for their clients (who mostly don't care about noise!). Those constraints may not necessarily apply to your mining situation. In your case, the SIZE constraint of the fans on your device has some significant wiggle room.

    What can you do with freedom on this constraint? Well, a lot, if you don't mind being creative. I don't know about the fanless idea you have – that seems like it could be interesting. However, it is actually possible to remove those smaller fans on the device and use a high CFM larger fan. The increase in size means a moderate increase in power consumption, but the benefits are less noise (especially that whining noise) and higher CFM.

    The other downside to the moderate increase in power consumption is the fact that you have to do a lot of the machining and fitting yourself – but hey you're a youtuber, that's just content!

    Good luck boss.

  13. I think that the hot air is not coming out straight to the outlet cause the “intake” temperature also raised, so it looks like the box is recirculating the air inside making the hot air coming back to the intake. If the ASIC does not stay in the middle of the box but right against the orange adapter you should get better results with the temperature

  14. If you only had 1 inline duct fan with the box setup, do you think it would be best to place it upstream (pushing air) or downstream (pulling air)? I might end up getting a second fan, but haven't fully figured out how it'll all work.

  15. I don't know – but I'm guessing the microphone on your phone is built for recording human voice. It may even be built to filter out high and low-pitched sound to improve recording quality. That is why I'm guessing an app sound meter is not very good for measuring the dB of machinery.

  16. Sound wave length. To effectively knock down sound waves you need to block 1/3 of the sound wave. Higher pitched sounds have a shorter frequency and are easier to sound proof. Lower sounds have longer wave lengths that are hard to block. Sound gets blocked by thickness of materials. 3" insulation is better than 2", 2' is better than 1", etc. The higher pitched sound got knocked down by material thickness of the box and the thickness of the shed materials which you saw on your dBAs.

  17. If you are worried about the exterior noise and not causing your neighbors to hate you for it. I would suggest an AC Infinity Duct Silencer. It is $70 and you would just need a 3D printed shroud and 8" ducting.
    Silencer: $70
    8" ducting: $18
    3D Shroud: ~$17
    Total $105, not bad for exterior exhaust noise reduction. If you want the noise reduction for inside then that is more equipment. About $200 more for a AC infinity fan and $30 for miner fan spoofer.

  18. THM, I don’t know if you been reading my post or not but as I posted before you do not need a sound proof box, you only need one 8” fan and remove all 4 120mm fans, also the PSU on the miner had 60mm fans you can replace with silent 60mm fans, I have been running this type of setup for a few years now from my S17’s to S19’s, I am even working on getting a custom shroud 3D printed that replace both the 120mm and 60mm PSU fans, using just one 8” external fan to keep it cool, again I have been doing this for years and it works, I have also used AC S8 infinity fans but the iPower 8” fans for $70 works just as good.

    Anyways best of luck but I posted this info for you on your previous videos, I also posted this info some time ago on Space design warehouse channel and I think he said he is working on getting a combo 10” shroud made, so yeah I am happy he is working on a 10” solution as well, vs 8” but you only need one “8 fan..

  19. all these asics have like years roi at this point and "years" in asics seems like a fatal flaw because in 1 year new ones come out that render the old ones unprofitable… does anyone know of one that will actually ROI and then some? Seems like they are all priced to never really be profitable… (at least in the current market)
