'The right to privacy matters'

No I couldn't find it at the Lowe's I was at. I got some silver insulation like that but it's non adhesive. I was just going to screw it on.

1/2" away from the has boards, thanks, I can make it like that. I'm still waiting on the delta fans but have pretty much everything else. I am going to do the wedges tomorrow, so it's all ready to go when the delta fans arrive.

I just have the one s9 because I only have one 220v circuit available for mining, the rest are 110v. Although now that this space heater s9 can run easily on 110v, I can get something else to put on the 220v.

yeah it will do 4th and 400 watts with one board.

if you have the older firmware from dec 2018 low speed does less and is quieter.

I just went to Lowe's to pick up the last items that weren't being shipped. Instead of the tongue and groove you are using (which looks nice in your basement BTW), I bought a 5/4" thick cedar board. Should I just use one of these, or should I double it up? I also have some cedar fence boards that are just under 3/4" thick, I could do one of each. I'm just wondering how thick I should be building these wedges. Obviously I want it close enough to channel the air but not so close it is a fire hazard.

did you get the foamed silver insulation I linked?

It is pretty heat resistant.

I had two wedges say 1/2 inch away from the center board.
I ended up using only the center hash board and I pulled the two outside boards.

I have around 26 s9s with five or six of them having dead boards so it was easy to make the one board s9.

I just ordered all the parts to do this mod and I am waiting for it to be shipped. I just flashed the firmware.

Phil are you running it with both LPM and LPEM boxes checked, as in the original pic? Or are you just running it with the top one checked now that you have the wedge mod in place?

It’s up in Clifton. You can try any combo they all work.

Ie

just LPM
just LPEM

OR check both.

I think both worked better then the bottom one LPEM alone.

Do due diligence

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

*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.

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

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.

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

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.

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.

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

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?

'The right to privacy matters'

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.

i love this.

would it work as a greenhouse heater for the winter? (i am a bit worried oh humidity/moisture/condensation on glass sides)

S7 or s9 controller and board?

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

Just Getting Started...

Quote from: sidehack on July 05, 2019, 11:58:15 PM

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.

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.

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.
