you must have some special tiny long 'hose' compressed air to be able to get at those lower heatsinks...

but then pretty much everything you said is based upon NON-ASIC hardware.

i am yet to see any ASIC hardware that doesnt need to be opened for one reason or another regardless who assumes to the contrary.. (please try to refrain from pointlessly mentioning single chip usb miners!)

since upgrading to 2.5.12 (the improve stabilty FW) - the fans were auto lowered causing overheating. Once that was 'rectified' despite silence from SPT i noticed that even with Max watts lowered the rig STILL runs hotter than it did on 2.3.46 FW





trying to operate at a profit means these rigs need to be running at optimal 24/7, anything less (including RMA) shaves off the limited profit potential.

or am i living in a cuckoo clock??

Please provide images of yourself cleaning the lower back heatsinks using compressed air - unless you are just guessing, which i assume you must be if you havent voided your 90 day limited warranty by opening the lid without permission!

Its pretty tight in there...

Sounds like your usage of the device isnt really covered by the warranty. As was mentioned, its common sense (and in the T&C) that most devices and electronics may have their warranty voided if opened or otherwise modified - often at the discretion of the manufacturer.

For cleaning the heatsinks use compressed air - works like a charm, and if you blast it in the back it works well to clean fuzz and dust out of the heatsinks.

Is there any reason why none of my SP20's hit the adversited hashing speed of 1700.  All of them are 1650 -1500. 

I never seen such issue. Please contact support regarding serial cable.
Workarounds I can think of -

- Boot from SD card (see technical blog) or
- Add cron to reboot daily (if problem always happens after X days) - you will loose 2 minutes of mining per day, which is about 0.25% - just set start voltage close to working voltage.

If none of this works we will RMA the unit.

It seems like sd or emc/ram issue. I do not have spondtech gear but this happens when linux file system or hdd gets corrupt. It happen to me with pi and broken sd card once. And with PC with corrupt ram or hdd many times
If spond gear has rs232 you can open shell. So when/if this happens again you can see Dmesg and some stuff eventually logged in console
In general you can reboot your gear power off on remotely with additional hw  

Thanks bud, but i already snipped out the front panel, and cleaned the ones that i could reach with a toothbrush.


i may post a pic or 2 tomorrow, and the next time i have a power cut i shall attempt to take the top board off to clean the lower back 9 heat sinks. (maybe check out the thermal paste? under there)

I have a rare problem. Sometimes SP30/31 occasionally stops working after many days of good work, and I cannot reboot it remotely.
The symptoms:
- it doesn't mine;
- I cannot open its WWW page (it asked for name and password, but then no communication at all);
- PING answers correctly;
- SSH every time shows "Login as:" prompt, but after entering user name, there is no any answer;
- the green LED at the front is blinking.

It looks like there was no free memory (but then I checked in the log there was free memory (348)) or no new process can be spawned.
The power off and on by hand is needed, which is a bit troublesome.

It happened two times before to one of my SP30 (which was then replaced because of misbehaving DC2DC circuits).
Yesterday it happened to SP31. (Two other SP30 machines work well there.)

The support is very helpful (Zvisha as always and two new people as well), but this time they found no reason, despite connecting remotely (after the reboot of course) and analyzing logs and settings. The problem isn't known and I don't want to waste their time more with it (until it begin to happen more often).

The stopping would not be as bad if I could restart it remotely. But, I suppose, the inability of communication is what cause the machine to stop mining.
It would be nice to have a watchdog working inside, which would restart the machine when such condition occurs (e.g. too many processes, low memory, connection problems...). To prepare it I need to know the exact cause.

So my questions are: What could make sshd to stop between asking for login name and asking for a password? Does it need to spawn new process? Or is it another reason like something wrong with TCP/IP? Do anyone had similar problem?

 since you only have 4 days on your warranty why not post a few photos of the issue and maybe some of us  can figure a way to clean your heatsinks.  right now multiple cans of air all at the same time with some external fans sucking comes to mind.  or a shop vac sucking with an air blower blowing and the  let the unit stay fully sealed. when I get my sp20 I may use 2 of these fans

http://www.ebay.com/itm/Comair-Rotron-032237-550CFM-10-Axial-Fan-Dayton-4C847-/111519168628?pt=LH_DefaultDomain_0&hash=item19f70f7874

as push pull with a variac as a speed controller and make sure I deactivate the stock fan .  this would cool better and would allow a quiet speed by lower the volts to 85 to the external fans.  this would also clean heat sinks if I speed the two fans up.

I am a compulsive tinkerer when I get my sp20 I will most likely do a long thread on how to make it work better. I will post 20 or more photos and I will post the policy that mentions you break it you are on your own.
  to be fair to the builders of gear they do need some control over people the tinker with the gear.

Thank you for the link, Is 90 days warranty the legal minimum?

Resenting the comparison (as i have come to resent some of the off-hand remarks that help no-one) doesnt make it any less factual.

Sam & his team would rather have his 'clients' homes burn down than fix the problems he and his team refuse to even acknowledge.


Please dont blame the end user for problems that are out of both our hands. If the rig catches fire or constantly shuts down because it isnt cooling properly then it needs cleaning... Obviously?!


Furthermore, my 3 month limited warranty runs out in 4 days, so rather than worry about it i have solved the overheating issue without the previously requested ability to turn the fans higher than 90. but it would be nice to be able to clean ALL the heat sinks as and when they need it. or should i just blow the crumbs of profit i might make on hosting the rigs and make a guaranteed loss?

I resent the comparison.
I agree that loosing warranty over cleaning heat sink is indeed draconian a bit. On the other hand, mishandling the ASICs, like applying too much pressure can cause damage.

Giy

cleaning would hardly be described as a physical modification (other than by notorious scammers KnC/CoinTerra)

that being said, i can find no mention of warranty terms on the spondoolies-tech site.

so either way, cleaning the heatsinks that i could reach seems to have helped.

the ability to adjust the fans to a higher speed than 90 may also help with my ambient heat concerns... i'm sure i mentioned that long before discussing opening the rig to clean it & thus voiding the warranty.

does anyne have a copy of these terms at hand?

i recall having to click on some agreement when first connecting to the sp20 but not the sp30.

i think it's not unusual for any kind of electrical equipment to have this - in fact the majority of electronic devices have that little sticker on them:
 'warranty void if removed'
it's not exclusive to bitcoin mining equipment and the same would be true for every PSU you buy.
if you expect to be able to tinker with the components and when you break it, warranty remain intact, you really need to consider the facts of the matter.
of course you are voiding a warranty, because you are changing the way a device works which is contrary to manufacturer recommendations.

that said, i normally mostly always strip my rigs to barebones, toss the casing to the corner and add extra cooling /fans. I would never expect, if I were to make the unit stop working by doing so, that the manufacturer would RMA the unit.

There is no need to do any physical modifications inside the unit.
Everything that should have been cleaned cleaned at the factory.

Some people, who are technical, changed fans or made emersion cooling systems and so far that didn't cause any problems.
But you must be aware that if someone changes something and the units stops working we have the right to decide that the warranty no longer applies because of the nature of the change or the way the change was done.
 

If cleaning them makes such a big difference it should have been done at the factory before the units were shipped.

cleaning the heatsinks voids the warranty?

how very sam cole

Please contact support.

Dear clients.
Please note that by terms of sale, opening the unit without explicit approval from Spondoolies-Tech engineers voids your warranty.
We can tell, when we get units, if they were opened.
Regards`

not a bad suggestion if i could find some locally. but it will be a bit of a mission either way.

since brushing the top sinks, my front temp has dropped from 41 to 39 and back from 90 to 88!

im half tempted to just snip the front 'mesh' panel out and brush the ones i can reach..

Maybe use compressed air the other way the fans blow

only Adv, IP-scanner. if that doenst work you'll need to contact support.


On another note - has anyone opened their sp30 up yet?

i took off the lid and brushed the heatsinks on the top board but found no way to loosen the seemingly sheared torx screws on the front panel to access the lower board/heatsinks...

any ideas other than drilling through each torx screw?

 i really need to brush those lower heatsinks!
