The input fan has a 7mm or 1/4 inch spacer. It is in the links.
Wood is quiet.
The silver faced foam fully surrounds the wood wedge.
Makes it fire resistant.

I plan to do some variations with the brains model which is in Clifton.

Price and ease of build has real meaning here.
You can mod an s9 in under 30 minutes and under 30 dollars.

I would do more videos and photos but I hurt my ankle early Wednesday and have it iced .

I am in my bedroom watching first type flippers while I type.
Ankle on ice for swelling☹️☹️

Hope to get back on my feet by mon or tue

I have an S7 currently down-clocked to around 3.7 TH. I think it would be better to swap in an S9 controller and a single S9 board along with your airflow mods. I am going to have to start scouring for parts Smiley

I think the s-7  is a little shorter  but the height allows for the s9 board to fit.

When you cut the 2   wedge boards they would need to be long enough to protect the s-9 board.

I should have a working model by weds or thurs. Maybe friday.

Is it just downclocked or also undervolted? Because you can get an S7 at 3.7TH to around 800W with an undervolt hack, and then replace the firmware with S7-F1 version you can run a single fan. Not dead silent but pretty quiet.

Obviously an S9 board is better, as you can get that hashrate from less than half the power draw. But it's still an option.

Also Phil's right, the housings aren't the same length. S9 is somewhere 1-2 inches longer.

yeah the s7lns are good for noise level.

But I am thinking if I use 2 s7LN cases one s9 board set to 4th with brains

It will be really good.

4th
38db
390 watts.

Psu will be built in.

Just downclocked via the software, I think I am running it at a frequency of 525. Is the undervolt hack the hardware mod in your thread? I looked at that, but I was not 100% sure what all to do.

S7 or s9 controller and board?

My hack is for s9 controller and s9 board with. Dec 2018 firmware.

maybe  maybe not.  worth a try.

I am still running the one test model



my apologies on not posting a second build.

but my ankle was slow to heal.

It delayed my trip to Clifton Farm.

We had a major net fail in Clifton and I have been pre occupied getting a better net setup.

So no action here.

but I will be going back to clifton this week and I will look to grab a few s-9s to toy with.

Did you consider just leaving all 3 S9 boards in place, only running the middle one but otherwise following your procedure with the delta fans, firmware and LPM?  I'm just wondering how much the wedge mod is worth doing vs just leaving the old hashboards in there to accomplish the same purpose.  I know you mentioned a 7c drop in temperature after the wedge mod, but was this from the case empty of the other two hashboards or with them in?

If the other hashboards still function, they can be used somewhere else instead of sitting as dummies. Waste of resources.

Also  the wedges work better at cooling along with the spacers I put in.

Might be more complicated than you want to go, but you might consider building an adapter to fit a larger diameter fan. This one moves 1.7 times more air at about same noise level.

Is there a way to run them without the controller?   If so then it would be a waste of resources but I'm not resourceful enough to know how to use them.

Technically yes, they could be adapted to USB and run natively with VH's NewPac/R606 driver. You wouldn't have voltage control (without additional custom hardware) and even with ASICBoost you'd be limited to about 2.5TH per board, which is around half speed. Note I have not tested this. Maybe if I get bored I'll prototype an adapter and see what happens.

However, controllers fail much less often than do hashboards so anyone running multiple miners for very long probably has at least one spare.

I would be very interested to see your prototype.  I'm sure you would make a thread about it if you get around to it.   Wink

And a custom case to fit one board to it... Hmmm i see a potential product here Smiley

take out the boards and turn them into pocket knives like these...
Cuda CY1

http://camillusknives.ru/2mainframe.htm?cuda/cam_cy1_en.shtml~main


*I'd post a picture of my old  CY1 pocket knife but I can't remember how  Grin

I left one of my undervolted S1's with a friend years ago and plan to eventually do something like that with the boards when he's done with it.
