several s19 units is 10kwatts.
as 3 x 3.4= 10.2 kwatts this is around 45,000 btus.
I have a 100,000 btu furnace to heat my home it runs under three hours a day on cold winter temps like 20f.
my point is you will struggle dumping heat if three are in a small space.
Topic: Help Making S19 Quieter (Read 224 times)
Why are placing the miner in the middle of the room? you want to exhaust duct to be as short as possible, post a clear image of the whole set-up showing the end of the intake duct as well as the exhaust, keep in mind that the S19 is nothing like the S9, and these APW12 PSUs are very sensitive to both voltage and heat, so even if the chip temps are good but the PSU is warm to touch, then you still have problems.
Eventually, I believe you will end up having an inline fan which itself will be making some noise that you might not like, any of these cooling methods are effienct enough, why? because these gears were not meant to run quiet, have you considered immersion cooling?

I have a few S19j’s coming, and I was looking at this method to reduce noise as well. I may have to rethink this.
I think you're good if you connect hoses directly to intake and outtake + add some good blowers in the tubes and keep the tubes as short as possible. It's not a bad idea to sound-proof the device using a box and hoses, but for +3kW you just need to be a little more sophisticated than with S9s.
The general concept is still fine though.
I would recommend to have a look at this blog post, he has a big power hungry miner as well:

I bought a cooler to do the enclosure trick I used to do with my S9. When I close it, the S19 promptly overheats.
3300w vs 1300w, the little air that was getting through those ducts was enough for the s9 but not for the new beast.
As the other said, either a boost fan or connect the fans to the ducting, although I doubt it will work for a long circuit.
I'm intrigued a bit about that picture, where does that duct lead to, I assume it gets cool air from the window and then blows it ..where?
Do you plan on using it as a heat source in winter? Either way, the best improvement would be to short the whole circuit a lot unless you plan on using some extra fans, and extra noise.
Probably a small blower is best.
I wonder if a grow tent kit would do the job, those things would be the easiest to latch on that setup.
Have you got inline fans in the ducting or are you only relying on the S19 itself to move the air?
I would buy some 3D printed ducts designed for the S19 which include the PSU aswell (yes they do exist). Then plumb it up front and back direct to those ducts in your box.
As gt mentioned - unless the ducting leading into & out of the box is VERY short you need booster fans as well to overcome airflow resistance through the ducts. The fans on a miner were sized assuming free airflow into/out of the miner. Ductwork of any kind - especially flexible ducts - add a LOT of resistance to the airflow. Considering the fans are rated for 250CFM each and we only need to consider one side (inlet or outlet, take your pick w/2 fans) that means you should have a booster good for at least 500CFM and >750CFM would be better.

I have shrouds to connect the fans to the ducting but I wanted to keep air going to the power supply.
The main reason for the overheating part is due to the fact that the hot air is getting trapped in the cooler! It doesn't matter even if you've perfectly aligned the intake and outtake fans to both of those holes [air moves a lot slower when there's an empty space between them].I have shrouds to connect the fans to the ducting but I wanted to keep air going to the power supply.
Note: I haven't mined in a very long time, so make sure to do more research on what I'm about to suggest.
- In theory, you should be able to detach the PSU [e.g. like how Bitmain did for "S17/S17 Pro"] and install it outside with some kind of bracket, then make sure there's no empty space between the fans and the holes.
- BTW, I don't think using a shroud to connect the fans to the ducting parts would be enough [most of the air would still pass through], so try to extend the insulated ducting instead [e.g. it should cover everything like in this picture].
A hollow object like such a cooler can actually work like an echo chamber for some frequencies.
I find the 'noise treatment' section in this blog post very interesting; the guy is an audio engineer. Some of the things he did may not do any meaningful differences, but he covered tons of factors and I can't think of other measures that he hasn't taken into consideration.
He even based the size of the container on the frequencies that his unit emits.
