New s9 upgrade thread. Some info is 🆙❤⚡

[philipma1957]

this is the latest s9 thread and will stay open this is not bitmain hash boards.

the builder has asked me to not reveal whom he or she is.

this is more,effficient then bitmain gear.

i have a one board and a two board build.

edit  I am doing 1 board mods only as I have developed an air flow idea that works much better as a one board mod.


Teaser for now.

Some info is below.

photos

right is new hash board the pcb is same size as s9 as it needs to fit in an s9 case.
note a blocked a serial number.
top has 7 caps  on pcie jack side of the board.

if you could the chips it looks like 51

the older s9 left has 63 chips
it has zero caps on pcie jack side of the board.



same as above twisted  for a better view



second photo

s9 is on bottom and has 6 caps
and burnt pcie jacks since it is an old hash board.



So 51 chips vs 63 chips

7 caps vs 6 caps.

the smaller shit I left out and won't get into detail with super close ups.

June 6 edit.

I am getting an s9 upgrade kit.

3 drop in hashboards.

If you have spare s9's you could hold them and wait for my test results.

The boards are due today.

Working firmware will be released to me on Monday.

I have agreed to not say the builder's name.

I have been told the new boards will have high medium low settings.

When I do testing I will test

1 board  miner on all 3 speeds
2 board miner  on all 3 speeds
3 board miner on all  3 speeds

info here and info at YouTube will be posted.

if gear is as speed and watts have been told to me. they may be worth holding onto your s9's for a few weeks.

Since I don't have boards or firmware or prices.

I will leave this thread locked for now.

I have told by the builder that

They are more efficient and they hash more than the s9e.

so they will hash higher than 16.0 th and burn less then 1280 watts

[philipma1957]

So I will set a three board unit up and show the hashing differences soon.  Maybe Sunday morning.

So pcb boards = same size.   this is smart enough. have to drop into the s9 case.

heat sinks = very close or the same.  makes sense as it is a generic part.



chip count        bitmain = 63

chip count.      mystery builder = 51


cap count      bitmain = 6

cap count.    mystery builder = 7


My goal will be determine if the gear does as well as promised.

Make some more s9 space heater units.


note I sold 7 pieces of braiins based gear and used 2 boards .  I don't want those people to feel screwed over.

So if this turns out good. I will see what I can do.

Those sales helped me talk with this builder into the idea of building better space heaters.

I will just see how if all plays out.  But if it plays out well those buyers will be happy they supported me.



I have finally gotten gear to mine.
I have some old controllers.
So I was to load this firmware into the controller via the gui option.

new bitmain firmware means burn an sdcard.

and load via sd card slot.

I will try that tomorrow.

Right now I set gear to low and auto tune.

I am running it to   btc.viabtc.com its mining away.  I will know iif it makes specs for low in the morning.

[MoparMiningLLC]

interesting - when you say mystery builder - do you mean these are not bitmain boards?

edit - I re-read it and see that you have another company making these - at first I thought you were modifying the S9's

[philipma1957]

Exactly they are a non bitmain company .

They made 51 chip boards vs 63 chips.

But the pcb board is the exact size as an Antminer board.

Here are some screen shots. showing a two board  running. the gui mining status and the pool numbers.

this uses 616 watts. to do 11th. about 56-57 watts a th.

I need a lot more testing on this.

I will be making  a you tube soon.



since it is a non bitmain chip the freq range is different then the s9 chips.

low setting with tuning tries freq 450 with best volts/watts

pll option allows you to pick any freq from 450-570 and then try to tune for best efficient numbers

since my hope is building better space heaters I asked if I can go lower then freq 450 and use the pll tuning .

so I am trying 2 boards and pll freq 400 option.

hope to drop hash rate to 9-10th and power to 520-560

auto tuning takes more then 20 minutes

here is a nice feature temp of every chip.
look at middle board it is not connected in any way  reads -99



freq set of 400 yields

watts at 531
hash at 10.31
only 51-52 watts a th

this is actually better then expected

looked pool side and I get

watts at 531
hash at 9.84 th
about 53-54 watts a th.  this is what I expected to get.

I use this psu and volts supplied to it are 240

https://www.ebay.com/itm/HP-643956-201-1200W-HSTNS-PL30-Platinum-Plus-Hot-Plug-Power-Supply-643933-101/312798058602?

My braiins gear does about 85 watts a th. I can set it lower then freq 400. so I can do 300 watts to 350 watts with a two board miner braiins. but far less efficient then this gear.

I will run this at freq 400 for a few more hours

I will drop to freq 350   to see if we can get lower watts and not lose efficiency.

It would be nice to go to 475 watts and 8.75 th.  on freq 350.


here are freq 350 numbers.

the settings



the hash gui
note that fan sensor is weird I will replace fan to see if it goes away




replaced fan. and get correct readings so fan had a bad tach wire.
looks like at freq 350   watts are steady at 463

and hash fluxes from 7700 to 8400.  I am going to run over night to see if it gets a more stable hash rate.

I will also see viabtc long time avg

if it does 8000 at 463  it is 56-58 watts.  if it does 8400 it is 54-55 watts

[philipma1957]

I like these hash boards so much I ordered some better quality fans and will test some more.

I locked the older s9 mod threads.

I would not mind having three 1 board miners using these hash boards.

hashing at 6th and using about 320 watts.

[MoparMiningLLC]

let me know when they come available, I still have one S9 I could swap them in on and see how it works. 1 or 2 boards would be great as it could run on 110 v - with proper fans maybe even be decent enough to put in the house lol

thinking of my grandson who wants to mine but has no job so he is not getting any large power hungry asic lol

[philipma1957]

the new boards need some work in terms of correct fan and best down clock.

The stock s9 fans are shit.  and i have a lot of old ones.

I ordered some higher end fans.

the ones i order for my sales thread were nice with braiins firmware which allow huge downclock and a very quiet miner that uses 80 watts a th. about 5th for two boards and four hundred watts.

these boards auto tune to 450 freq at about 55 watts a th.
but that 5.3-5.5 hashing at say 325 watts. it has flakey tuning i kind of want to play with it more.

[MoparMiningLLC]

55 watts per th isnt bad especially if you can run them on 110v - will allow for a lot more home mining if they have decent electricity.

[philipma1957]

It cycles a bit when it tunes.

Older Avalons would do this. Some times they would boot every 2-4 hours or

It means fans pick up speed just a bit every 2-4 hours.

I know the fans I am using are some of the lower quality ones bitmain would use on s9's

I am hoping to get the gear to run really stable with out upticks in the fan and or reboots.

At 55 watts  a th for a lottery machine burning well under 400 watts closer to 290-310 watts it should be good For space heating and pretty quiet.

New fans come next week.

Now if you just want to run it with 3 board at low speed  and don't care about noise   I am doing 910 watts and 16.1 th about 56-57 watts a th at the k-watt meter.

I use the 1200 watt hp psu blue jack for platinum. Found on ebay for cheap

https://www.ebay.com/itm/HP-643956-201-1200W-HSTNS-PL30-Platinum-Plus-Hot-Plug-Power-Supply-643933-101/312798058602?

[MoparMiningLLC]

when they come up for sale, let me know.

[philipma1957]

I hope to do 1 board miners

that do 4.8 th at 266-286 watts

the three testing boards were sold to me for the shipping cost  about 60 USD from asia to USA no taxes due to cheap price.

If the new fans come and don't get lost with fedex I will have 3 fully operational next week.

I will also be talking with builder about purchase of boards in order to make more of these.

I have some very specific ideas on one board units I think I can mod inside of the s9 cases in a better way.

I would like to get the units to run at 500 or 550 freq

I have tested

freq
300 -------
350 ------- 228 watts and 4.1th good sound levels
400 ------- 266 watts and 4.8th good sound levels
450 ------- 291 watts and 5.3th a bit too loud
500 -------
550 -------

[MoparMiningLLC]

well when you can get more - i would be wanting 4 boards - I have 2 s9 cases would do 2 boards per case. the S9 boards I can sell or even donate to sidehack to use for his r606's maybe.

[philipma1957]

two board run decent.

My issues so far are quiet. not efficient .  I can get 53 to 59 watts on different settings   which are within the specs I was given. 54 to 60. with 54 at the 450 freq setting.

The new fans come next week I will see what I can do.

I will also ask them for boards.


I did a different one board design. I have same shitty fans.

But my airflow  is working better it Seems good.

not very loud.

but nice temps

on middle setting.

6.3 th and 335watts.

the mod takes ten minutes.

it should be fire resistant.

[Artemis3]

this is the latest s9 thread and will stay open this is not bitmain hash boards.

the builder has asked me to not reveal whom he or she is.

this is more,effficient then bitmain gear.

i have a one board and a two board build.

Oh noes this is not fair... Does it use the same Xilinx controllers? Did he supply its own custom controller?

Will this mystery maker ever use the R4 form factor? Because that's a winner for a heat spreader right there...

Is this going to become commercially available for others?

I wonder what chips are those asics...

[mikeywith]

Oh noes this is not fair... Does it use the same Xilinx controllers? Did he supply its own custom controller?

Yes, it does.

It cycles a bit when it tunes.

Older Avalons would do this. Some times they would boot every 2-4 hours or

It means fans pick up speed just a bit every 2-4 hours.

Phill, this is pretty normal, I ran a custom firmware on a few gears and some of them needed over 10 hours, some even need a whole day to actually stop rebooting, the reason why this happens is the fact that the step-down settings are set at minimum to ensure that you are getting the best of each chip, so even if 50 chips are lowered to the frequency they like and you are left with 1 chip that needs to go lower, say chip 5

chip no 5 > frequency 450 > run for 5 mins > collect results > bad > lower frequency to current frequency -1
chip no 5 > frequency 449 > run for 5 mins > collect results > bad > lower frequency to current frequency -1

sometimes a chip may only run well at say 350, so that's nearly a 100 steps-down if each reporting cycle needs 5 mins that's 400 mins or nearly 7 hours, and then eventually that bad chip might actually not like the voltage at all, and then voltage needs to be changed and the auto-tune starts all over again, so you should allow more time, let them tune for 24 hours, if they fail, then go with the lower settings.

[philipma1957]

[...]

I use a bitmain controller I have a lot of them mine had old firmware and I was able to use Bitmain gui to upgrade it.

Most will need to burn a micro sd card and move the pin to boot with the card.

I can make a really good one board out of it.

I came up with a very nice way to maximize cooling off 1 board.

Running the unit on low with lessor fans I can keep chips under 80c and fans under 3000 rpm.

note how exit chips are warmer.



below it fired up on low with custom 3000 rpm fans
the flow design I did seems to work on keeping chips cool

[mikeywith]

What is the best Watts per TH you achieved for this type of cooling with a single board? also, it would be best if you ask the "mystery maker" about the max temp their chips can handle, 80 is pretty good for the regular BM1387B/ BM1387 chips but it could be a bit high for the new chips, so better safe than sorry, especially that you are planning on selling these gears, so it's not just about you losing a few boards, but also getting yourself in troubles with your clients.

Good luck with this great project phill, let me know if you need my help at any point.

[philipma1957]

With the new air flow design I can get 54-56 watts.

But this will take a lot more design and testing.

I have good 3000 rpm fans
I have shit 6000 rpm fans

I am waiting on really good 4900 rpm fans.

When you are making a niche product you some times have to restrict  stuff of it fucks up.
I need to know what fans are strong enough  but not too strong as I am not trying to run hard and fast and loud.

A one board unit burning 295 watts and doing 5.3 th is about 55.67 watts

I have a lot of testing.  As I don't fully understand the firmware quirks.

I need to know what pools work.

Ie.

I want to get it working with solo.ckpool.org
I want to get it working with mmpool.org

I have it working fine with viabtc and slush.

[mikeywith]

With the new air flow design I can get 54-56 watts.

That is pretty much T17 efficiency which is very impressive, those guys did a great work for sure.

I want to get it working with solo.ckpool.org
I want to get it working with mmpool.org

It probably uses cgminer and almost all things pool related are the same so I wouldn't expect any issues like this, it will work on those pools without a doubt.

Took the image you posted above, I like how it shows the temp of each chip



I think the design can be improved, the chips I circled are located right behind the fan's motor, and they tend to get hotter than the rest, the design on the normal S9 board is better as they leave a few empty slots in the middle like a V shape, you might want to discuss that with the maker, you could also use a spacer to allow more cooling for those poor front chips, that will allow you to run fans at even lower RPM to save a tiny bit of power and get some noise reduction.

[philipma1957]

The newest design has a spacer .  It is why I have been getting away with the 3000 rpm fans.

I use 4 things
Some 2 by 4 wood
some silicone epoxy
some metal tape
some screws

I cut 3 pieces of 2 by 4 into trapezoids
I silicone them into 1 piece
I wrap them with metal tape
I put them into an s9 shell.

You can use wood glue or silicone epoxy





here is a you tube of assemble with silicone epoxy. it is in 3 parts.

1st video

https://www.youtube.com/watch?v=KYw5PxWqRSg

2 more videos coming.

more on assembly of air flow guide

https://youtu.be/Ttt5HsUUDI8

third video will come in a while as YouTube is slow to upload  today.

I am really pleased with these  air flow mods.

https://www.youtube.com/watch?v=QNri1LpEGAU&feature=youtu.be


At this point I am going to run 2 1 board units over night.

They are fully built and I will be test and comparing them for 3-4 nights.

In 5 nights I will be running a third unit with 1 board and really good fans hi end long life fans from san ace.

made of metal not plastic.  they are 4700 rpm fans and fairly quiet.

So I should have 3 comparison units. fully tested by next weekend.

[ATCkit2]

Very interesting thread, Phil. Great idea for space heaters with decent efficiency.
Please let me know when you have dashboards available for sale or if they can be purchased from the "mystery builder".

[philipma1957]

I asked for pricing on :

   10
   50
 100
 500

boards.

Mostly depends on what he or she tells me for price.

These make

quiet one board 290-320 watts about 5.5 th

yeah you can do a two board but so far I can’t get them to be quiet as  I like.

and of course you can do a three board but fan speeds on low setting make them pretty loud.

So far simply set to low speed and let it tune for a day.

after 15-16 hours it locks in and does not reboot much.

I will be getting a covid-19 antibody test tomorrow. As will my wife.

we finally have them available to take.

I am hoping they find antibodies in both of us.

we were both really sick in Mid Jan.  I fully recovered,but my wife seems to have damaged her sinuses as she is now on month five of a post nasal drip. Simply can not stop 🛑 it.

Good news for her is the O2 meter we got read 96,97,98 % and even 99%

when she got out of hospital 🏥 it read  91,92,93%. so what ever the double pneumonia did to her lungs is healed. her temps are 96-97.9 last 70 days and her pulse is 67-78. unless she had a cough fit from the endless post nasal drip.

we will be going to more doctors for her once we get the test result.

This is all not off topic even though it seems to be.  I and my wife have been spending tons of time with different treatments and studying many pages of info on meds and treatments. So it slows my btc work.

covid-19 and now the protests and riots have slowed me up a lot this year.

[ATCkit2]

Yes- we live in crazy times. However, we did survive the 70s... when we all felt tomorrow could be the day the nukes are unleashed. I think most of us will get through this too. I'm sorry to hear your wife has had such a hard time. Nice to see her O2 back to a normal range. My wife had a double lung transplant last fall.  We all forget how vital this organ is.

Nice to hear you have the antibodies test available there. After such a rough Winter, I hope they find antibodies in both of you. The next thing is "how long will the antibodies last"? I know they're collecting data on that. Hopefully, they last at least until a vaccine is available.

[philipma1957]

We just got back from blood🩸 drawing.

Results on Friday.

If we show positive antibodies we will look to see a few ear 👂 nose 👃 throat doctors.

Years ago I had my nose 👃 cauterized due to endless post nasal drip 💧.

It worked pretty well.

I will also be able to go back and forth to Clifton and work on the mining farm more.

I am talking about getting a large board order for these boards.
I hope to get a reply today.

Depending on deal offer and time line I may ask for pre order money 💵 but I really don’t want to do that.

Ideal would be an order of 750usd worth of boards.
Get the boards.
Then another order of 750 usd worth of boards
get the boards
then another order of 750 usd worth of boards.

No news on boards but china is locking down sections again.

Note: this is from another post of mine

https://bitcointalk.org/index.php?topic=5256466.msg54642018#msg54642018

To all don't order from China for a few weeks. ... "

I got the high quality $50 usd a piece  fans I got them used for $14 each.

They are so good you only need one like an older Avalon
I also redesigned them yet again and look at the cooling



only 3 hardware errors



I have another fan on order I will build the unit with that and test. I will also do a movie today.

[MoparMiningLLC]

can you share where you got the fans - I would like to have some back ups and better fans are always better - I assume they will work on all the antminers?

[philipma1957]

This is the video I just made.

https://youtu.be/6niZ_J37x1U

maybe have to think about it.  they need to be spliced as they come cut.

check video.

[MoparMiningLLC]

wish you had shown the temps of the other one with the  better fan.

[philipma1957]

Battery died it is charging.

I have come to the conclusion that the 120mm x 25mm 3000 rpm delta's are not good enough.

The better fan does work well it is all metal 120mm x 38mm. 4900 rpm A guy on eBay has 10 or more to sell.

I can set the gear to normal speed in a warm room. 85f

lock the fan in at 50% minimum and it does the job

Here are current settings 'normal'

takes an hour to tune somewhat

room is getting too warm 86f

https://i.imgur.com/cZkoA47.png

I am going to eat lunch

I will show temps
I will show hash rate
I will make YouTube

2-3 hours


https://i.imgur.com/BfzUAMp.png

That is the better fans running as a pair I can go to highest speed with no issue.

To update.

I liked these boards and made inquires into purchase of

  10
  50
100
500

boards.

It has been more then 2 weeks since I asked so I have decided he may have no interest in selling to me.

After much testing I did discover a 1 fan push worked best for cooling and saved more power.

Kind of like the older avalons.

I was able to get very good numbers at normal speed. which is a freq of 510

I did 6.1th and used 340 watts  this is 55 watts a th

since the builder has not offer these to me in bulk and i have 3 boards in 3 separate units I will most likely use them to space heat the house this winter.

[qctechno_isback]

I love the numbers, perfect small space heater with good efficiency ( not cutting edge but super respectable ). I'm seasonal miner now, quiet space heater is huge market IMO. Lot's of friends wanna mine and heat but can't handle a 3KW+ beast mode miner.

I'm following your thread closely, waiting for price per board.

[philipma1957]

And a  new update.

I was replied to on June 16th it went to my spam folder.

My bad.

They told me they have a 600 board minimum. I replied today letting them know I could be interested in a 600 board shipment.

Details are pay 1/2 up front

3-5 weeks to set up the assembly

1 week to make the 600 boards.

So In theory if I pull the trigger I could get them 6 weeks from now.

Frankly I do not need 600 for myself.

I could do with 60 to 100 for myself.

I will see what price with shipping to New Jersey , USA   will cost for 600 boards.

I will post back when I get a reply.
I will check my spam folder a lot more closely  

[gt_addict]

Are you thinking of selling the additional boards on? Would you be selling just the boards or complete "plug and play" units Phillip?

[philipma1957]

Well frankly 600 boards would be 200 to 600 miners depends on the  boards per unit.

I have 28-29 shells. So even if I build 28 miners to use at the Clifton ware house that is 28 x 3 = 84 boards

so I only need 84-100 boards.

Assuming the offer for 600 boards is a decent price.

I would have 500 boards to sell.

I am not going to source s9 shells 🐚 with controllers and fans.

I would need to be able to sell 500 boards. I am not sure of the demand for that many boards.

Remember while these are pretty good doing 55 watts a th. they are not super good. say 35-40 watts a th.

Now I will wait and see what he wants to charge me for the order of 600 boards.
Lets say I like the price.
I need to see what can be done to ensure delivery 🚚  of the gear.
I need to see if someone wants boards.

Well if the price is good enough I'm sure there would be a lot of people who would like to convert their S9 paperweights into something useful. Break-even for 55W/Th is about 5.6c/kWh. Could work if the price is around $60 per board. Of course if BTC tanks you'd be left holding the bag unless you got commitments before ordering.

Well we can forget about this project.  I just got pricing for 118 a board.

Even if I go  with custom 2 board  build designed for quiet. 

 Parts would 2x 118 = 236

Shells are 30-40.    =  276

Newer fans            =   14
A few other parts.  =   10

a grand total of     $300 for a 2 board that does 10-12-14th. and uses 550-660-770 watts

  This is my cost to build it.  So even If I restrict to USA only.  it is 30 to ship

330 cost at zero profit for me.   Not going to work.

yea they are wanting too much per board. good job on the work you did but yea I dont blame ya for not going in on 600 boards at that price.

[gt_addict]

Yep thats not worth doing. You need to be making something for all the time and effort in building the things.

[mikeywith]

If we ignore the noise, and use 3 boards instead of 2, total cost will be

3*118 =  $354

so 21th at 55w/th  for $354  or 42th at $708, that is like buying a T17 42th for $708, now if someone has a dead S9 that is worth nothing and APW3/7 that sitting there doing nothing, this might be not to bad a deal, for the following reasons

1- T17 quality sucks
2- T17 Requires 220v while these can work with 110v and don't need a stable voltage
3- The cost of power supply on T17 is about $200, while a used APW3/7 can go for as low as $10
4- If you lose 1 board on a T17 that's about $200 gone, and only 50% of that if you lose one of these boards

With that being said, given the efforts, it might still not worth $118, my initial thought was 60-65$, given the lack of gears supply nowadays I think they will do just fine with about $75-80.

... given the lack of gears supply nowadays I think they will do just fine with about $75-80.

agreed with this - at that price, I would fit the two shells I have and put the psu's to use. right now they are just gathering dust.

[philipma1957]

Can’t do 600 x 118 =  70800. and I may get stuck paying 18000 import tax.

yeah they need to be three board .
set to normal
about 1150 watts and 20th.

[NotFuzzyWarm]

Too bad as I have dead s9's up the wahzoo and would have been interested in being able to reviving a few of the carcasses by using new innards. Ah well.

yeah disappointing.
My 28 s9 shells 🐚 could have done 560-600 th

vs 300-330th

and use less power.

Not that interested in a group buy as I don’t  want to handle the funds along with the risk of trump tax.

I was hoping for lower order level and lower price.

But parts and setup are costly for builder.

[Artemis3]

All right, its not good for you. But can't you ask them to directly provide their service here, or via some website? Not everyone lives in America.

They should just use their own company name, and sell them as "s9 form factor boards" or such, with their own controller. So all they would sell is controllers and hash boards.

Honestly those franken S9s should not be called S9 at all, they have nothing from Bitmain (unless the chips themselves are the ones from the newer families, but do these each report temp? i know the inno ones did). I'm surprised they are not already selling a whole miner that way. There is market for "half a T17", for example.

The min power requirement of the latest units is getting ridiculous. The way things are going they might as well skip with the home stuff and go straight to industrial plugs...

Shells are plenty on ebay and alibaba, and if demand comes, someone would keep building them (especially in China).

Not like the S9 shell is any worth preserving... It just happens that there is a lot of them and could see some reuse.

[philipma1957laptop]

they monitor thread.

I would think if they want to do sales here they can post.

They told me 600 board minimum.
1/2 up front. 118 usd a board.

maybe they will offer a sale thread.
but for me in the usa they are not a fit .  maybe they are a fit for you.

they are using the shell and the controller along with fans.

and the wires .

Semantically speaking s9 up grade is kind of accurate. your name is also accurate.

but my conditions were not to reveal builder so if he wants to post and try to do  sales he will do so not me.

He knows it is not a fit for me.

[AniceInovation]

Is it a chinese company or something from europe?

[philipma1957]

They are not based in North America or Central America . I am in USA package was sent from a foreign Country via DHL.

It is pretty obvious to me since they are not posting here so my guess is they do not want to sell here.

[mikeywith]

Is it a chinese company or something from europe?

My best guess is they are from China, or any other Asian country for that matter, cost wise U.S and Europe can't compete with China as far as mining is concerned, so nobody in their right mind would try to make those boards in EU.

.It is pretty obvious to me since they are not posting here so my guess is they do not want to sell here.

I find it strange, they do seem serious, you have a proof that their hash boards work as advertised, yet they don't seem desperate to sell their products, it is possible that somebody found his way to them and bought everything in bulk, thousands of S9 control boards are lying around doing nothing.

[MoparMiningLLC]

i would buy maybe enough to do 2 s9 shells and then donate the s9 boards to gekkoscience for his r606's.

[philipma1957]

I was looking for 100 at most.

600 minimum and import tax make them a no go.

They have chosen to not post here. I would guess they found someone. And built out  a run for them.

BTW with the crazy heat we have had 2 boards shut down on two units.

One still works.

But they were being torture tested as input temps are 95 f  and output temps  of mining room are 110 f


the one that lasted had the higher quality fans.

all fans are under the rpm of the normal s9 fans.

I Used 3600 rpm 150 cfm fans and they were not good enough

The 4800  rpm super high end all metal san ace is working great.

So i would say the fails are a reflection of the fans not the boards

[mikeywith]

Phill. Can you check in with these guys? Are they still selling? Did they change the moq and price? I lost thier contant.

[philipma1957]
