Unofficial Spondoolies SP20 thread

[jonnybravo0311]

Great writeup Phil.  Having owned an SP10, and dealing with the ear-piercing scream it put out, how do the fans on the SP20 compare in pitch to those fans?  I don't mind something a little loud as long as it isn't that awful screeching whine.  Don't suppose you could grab a quick audio clip of the fans at a few different speeds and post it could you?

They are just as loud, but personally speaking the pitch on the fans is much more tolerable than the SP10.

Thanks Bob.  Like I wrote, loud is OK as long as it's not screeching.  The miners are in the basement.  With the SP10, I could hear that thing throughout the house, even with the fans on their lowest settings.  I had an S2 and couldn't hear it.  I've currently got 8 S3s and can't hear them either.

still looking for the db meter.  getting too much gear in the house.

I am running 10 s-3's  and 1 sp20e  

I have 9 s-3's in the garage near the work bench and I have the sp20e


Figures I set the gear all up and temps jumped to 74f .  making the attached garage 92f and making the house 85f had to shut gear off over night to be able to sleep.

Today is cooler around 62 f house and garage are both better.

 I will photo setup.

@ sbogovac    raskul was helpful in selling it to me.

@ raskul    thanks.  and I am send some more hash at mmpool

3 s-3's and 1  sp20

they stack well and air is feeding out my garage's back door 2 quality psu's the egva 1300 g2 and a seasonic 1200 watt plat.

my garage can safely do 5k watts I have 5 20 amp 120 volt  circuits  into it.  when i am running all 10 s-3's and the  1 sp20 I am at 4.kwatts

for now the issue is heat since it is about 57f the garage is warm but my entire home is also warm.  So realistically  I am close to max. my hashrate is 5.5th .

 I could fit 2 more s-3's or try to arrange a few more sp20's .  my 10 s-3  to 1 sp20  =  5.4th 4kwatts

should be  5 s-3's  to 3 sp20's  = 6.5th same 4 kwatts.




3 more s-3s'  they are above the fist photo

the gratitude is all mine to you Mr Ph. the small commission earned from your sale went towards a month hosting on a couple of SP10 that I had in SP-Tech datacentre.

re: mmpool, i reckon everyone mining with SP-Tech gear should try it out for a round and see what they've been missing

You'll hear the SP20

Don't get me wrong, I think its one of the best miners out there and I'm probably going to get another one soon, but don't think that its quiet like an S3 or a Jupiter.

What level was the fan in that video, 80%?  Definitely not anywhere near what the SP10 was.  Loud, but low-pitched enough that I wouldn't hear it from the basement.  Thanks for sharing that video Biffa!

is that there SUNSHINE i see peeking through that door?

You want to bring some of that to Scotland, there's an APB out on it, hasn't been seen since the clocks changed

yeah that is a lot better then 40 or 50 setting. I can get away with it as it is in my garage but if you have an apartment not a home the sp20e is loud.

gotta say what a nice piece of gear compared to the asicminer prisma.




comparing this to the newest ant miner s-3+ that has voltage and freq settings is tough.  you can argue a lot of ways as to what is better.

since the sp20e uses 1 ethernet wire cost shipped to the usa is about 910 usd power settings allow for 750 watts and 1350 gh fans is loud.

the s-3  4 of them cost  1034 usd you can set them to do 4x 450 = 1800gh and 1350 watts.

 both are under clock under vote options.  

  if you have a lot of room and cheap power the s-3 may be your choice.

if you are tight on space and power costs more the sp20e is better.

a blend of the two may be better for some.

I think these two are the best gear around.

s-4's and or sp30's have never entered my testing space. so tough to say what I think of them.

as a 2.5 year miner my choice today is an s-3/ sp20e mix.

I run it with a s-3   so the 2 unit's on the evga 1300 pull 1100 watts and are doing 1330 + 466 = 1796.

I get nice cool numbers with fan at 60,but it is loud.  I have a way to manage sound.  see photos of white fire blanket and blue moving blanket.  I will pick up a few pieces of sheet metal on black fri.



 I think I will buy 2 or 3  more of these and sell off 6  of my s-3's.

3 of these would use 2250- 2400 watts with under clock get 4th
4 of these would use 3000 - 3200 watts with under clock and get 5.3 th

I wonder if someone had adapted a garden box (wooden or plastic) or a small shed to put miners inside.
If you have done this with any miner-let me know, I would greatly appreciate it.
I am looking for a solution like this so I can enjoy Sp-20 or some other miner(s) outside of the house-I have small patch of a garden, so I cannot put a large shed in.
Garage would not work for me because I live in a 40-50 house gated "community" and I don't want people who walk around to peer at my equipment constantly.

Okay I purchased one last week it arrived today. I will show lots of photo .  I will test it on various settings with different psu's.

Thanks for the review.
My 2 cents:
In your underclocking settings the miner is running cold, and you can set the fans to lower settings for sure.
As long as none of your ASICs above 100c, your fan setting is too high   They can go to 115c before throttling starts.

thanks for info.  but some of the time I close the garage door and I then need the faster fan.  for me I can  manage the sound of the fan at 60 rpm.

this is the asic temps with fan at setting 60 and garage door closed for 15 hours.  with these numbers I don't fear a meltdown when I travel out of my home for 1 or 2 days.
