I have 2 SP10's, 1 was a slow corner the other a fast corner model. Today I found the fast corner idol, upon reboot I noticed a strange glow coming from the intake. Yep she was a blaze, intake temps are 29c as always so it was not excessive heat, looks like the advertisement as a "professional" piece of equipment was ALL hype. At less then 10 months of operations and she is up in smoke, to date I have 30 antMiner products NOT a single fire yet. SP-T has joined the ranks of "Fire-starters"..  Ugh what a let down, there goes buying a SP31 and now I have to worry about my remaining SP10 and SP20.


Pics to come, have to feed the family before tear down.

could it be dust? I always worry about this for any miner-eager to see the cause.

pics or it didn't happen

Which part of the SP10 started the fire? Would be v+helpful for debugging.  
My guess is a wrong voltage rated cap.

"i'm not buying GEN2 because GEN1 had an issue"

like...

"i'm not eating steak because the chicken is bad"


 :D

LOL Raskul, I am not buying it because they are over priced, which was "excused" because they were a "better" built piece of hardware. I NO longer believe that and in fact I would say these POS are REALLY EXPENSIVE AM Tube dangerous.

So anyone from SP-T see the problem?  This machine was running in a Rack with 29c intake temps, on 220v power.

Now you are just being silly comparing an SP-T miner to an AM. Also use imgur for pics...yours are proxy blocked.

All they're seeing for now is "bitcointalk.org image proxy: Invalid image" :)

Looks like a suspicious link:

Most likely an attempt to discover IP's.

I wish I was, thank GOD I was on site when it went up. There were visible flames as I reached to pull the plug.

Sorry for the technical diff..  had file permissions set wrong, vpn is under repair..

LOL even the peanut gallery?? S.A.D

While I can not rule that out, the 33 other machines in the room seem to suggest different. Obviously the board is NOW dirty, cap blew dust everywhere. Guess I need to pull a board tonight..  JOY!!

Really I would say the heatsink came loose/ lost contact to that section of the board. Since I was unable to speak to machine had to do a hard reset, the temp of that asic bank was probably reason for machine hanging. Lesson I suppose is after a few months of ops, you should tighten mount points. Now where is my SP10 manual, maybe their website..  HAHAHA  LMAO yep "The best CS and most professionally built".

Might want to shut your SP10's down for a quick inspection!

Ok, so you want to play the part of being an intelligent human being? I got you covered.

First, [all!] Electronics fail.
Yes, even medical grade electronics that are critical for sustaining a life. (redundant electronics necessary)

Second, you seem "surprised" because an SP10 caught fire, you therefore seem to consider it an issue of quality.
You also stated "you were lucky" because you were there to pull the plug. (?) <--

I am guessing you aren't properly hosting said device to be worried about burning down the place where you host them.
Not taking appropriate precautions is the bigger issue to keep in mind.

---------------------

Next, I see your SP10 did fail, (like all electronics from all manufacturers eventually will).
The question is, how often do these fail when operated properly.
I don't recall seeing many SP10's failing in this board. So I assume they are safe enough.
But don't take that as a sense of false relief, instead be prepared for when they do fail.

You stated you have ~40 some Ant miners. I am guessing you haven't set those up either in case of a fire in one unit.
Again, you don't sound like you are prepared for that eventuality.

Recommendation --> STOP overreacting.
There are no hardware from all these manufacturers that are not liable to catch fire.
Avoid the ones from manufacturers that consistently do have known issues.

When they do catch fire, have a plan in place.
If you don't, you might have one ANT catch fire and take out the entire [ANT farm]/lot.
It is ten times better if you had a plan for when you aren't there to watch for a fire.

Thank you for reporting the issue with an SP10, but it sounds like you have alot more serious issues than just one box that recently caught fire.

LOL You have an amazing ability to remote view my mind and my data room, WOW!

I did not say Thx GOD, because I was afraid something was going to destroy my place. Even it I had let her burn at best it would have caused the building to stink. But hey thx for the free anal-lysis it was really helpful.

Likewise I agree shit fails, the difference is will it catch a blaze. I have had several ants fry the difference being they popped, smoked, dead. This SP10, like the AM Turds, caught a blaze which did not extinguish without aid.

Thus FIRE STARTER!

Sometimes stating the obvious is necessary.
Try not to make a fool of yourself.

What on Earth are you saying? How do you even know one thing about my preparedness?

I've had two SP10s in my custody for hosting since about July, and this has happened to me three times (twice on one machine). One of them blew a VRM in January when the intake temps were about 14C. That grey bead to the uppper right corner is the only connection between your VRM/bank and the 12V rail, which means if you're worried just remove it and thew hole burnt section is now electrically cut off. Both my SP10s still work at reduced capacity.

When we're talking about fire, is it safe to assume that this one self extinguished?

Thanks for that HELPFUL comment sidehack, that would be best case to save the remainder of the board's functionality.

Negative, had to pull from rack and extinguish with wet towel. Did not want to over react and kill the room.

I just bought a 15# halotron for events like this.  I would recommend the same.  you can get them NOS for around 120-150$shipped on ebay

Mom says: You look prettier when you don't say too much.

(I am really joking, but thanks for saying too much)

You could also do what AbuGarcia says, but those are pretty expensive alternatives. And consider you might not be there when it happens next time. Might want to look into a kit triggered by smoke. One integrated with a breaker box. (Halon has it's problems.)

Sounds like your mom gives good advice you should take it.

Yes problem with Halon bomb is it shit cans the rest of the GOOD equipment. If these guys like AM are planning to shove 5KW thru a board I would have to say NO THANKS!

 S1, S3 are solid had several pop but never ignite.

S5 same low power unit as S1-S3, SP20 being smaller but using the same power using 1/2 the power as SP10 leaves me feeling better.

@whonesta contact sales@
We would like to buy the SP10 back for analysis.

Regarding SP20, we had to date zero reports of similar issue.

Thanks I imagine it has a story for ya. And after looking at the SP20 in OPs, I was incorrect about the power usage, like the ant's it too is a lower power unit.

Email sent. Subject: SP10 Ignites

If you do your homework on Halon and it's various alternatives, you can apply "an equipment safe" alternative to water. (hence why I mentioned the (general kit) with a breaker function.)

Halon does not always entail damage to Good equipment. If you design things properly you can avoid that without too much trouble.
Don't take my word for it, just read.

----------------

On the S1 through S3, these are subjective opinions. You are putting yourself in an area of misplaced confidence. It will eventually happen even in the best of situations.

If you lul yourself into a false sense of manufacturer superiority then you'll pay for it big time when your time comes.

Ugh man you have been of NO USE on this thread, your information is erroneous and off base, please GTH! I have had ALL miners fail, I have had 2 which have caught a blaze and failed to extinguish without intervention.

I'll GTH...but when you suffer the consequences of misplaced "ideas" i'll keep your seat nice and warm. LOL. Some never learn.

!

I hope it would have self extinguished if you had wait..

Glad no one was hurt.

Halotron is not the same as halon, halon was started to phase out of circulation more than 2 decades ago because of ozone depletion.  
So you have two choices:
Halotron
or
3M novec - which is about 300 dollars a gallon.

Yeah I am phasing out miners with a draw north of 1000w, in my experience that is the threshold which leads to fire. I have had the lower wattage miners burn up, but never with a resulting flame. Shrink the mine down to 20TH and hold, expansion with current return and specs on gen 3 just does not make sense. 

I like these for automatic fire extinguishing.

whats inside?

not sure how thats really the problem - power density is a greater issue than overall power. SP3x draws >2800W but is extremely reliable. KNC draws 300W/box and caused dozens of fires (generally all related to wiring though)

was the SP10 running at full specs still (1200W/1400GH) or was it undervolted (770W/1000GH)

Please, don't be smart (or informative) in front of him. He really hates that.

They were my units hosted. Luckily Sidehack, the hardware guru that he is, had them both running at only a slightly reduced speed the same day. If you're looking for hosting I truly believe you won't find better.

Cheeseater, SP tells me you should contact them about those two units. They might want to buy them back so they can analyze them and find the problem, same as they said to the OP.

Like I said, you won't find better hosting anywhere. Pm'd Spondoolies Thanks!

I was operating on the assumption that the SP10 was reliable as well. It was running @ 1kW/1200GH, 80% fan.

She is heading back to SP-T, I hope they are able to discern the cause. Make the MEGA mines safer....

No idea but it says it is safe for electronics.

What's safe for electronics might not be safe for people .. please check what's inside before buying.
 

Especially if that 120 dba 'warning' sound goes off near people.
