Here is a datasheet for a typical remote diode temperature management/fan control IC.

http://www.ti.com/lit/ds/symlink/lm96063.pdf

Note: "The LM96063 is remote diode temperature sensors with integrated fan control that includes remote diode sensing. The LM96063 accurately measures: (1) its own temperature and (2) the temperature of a diode- connected transistor, such as a 2N3904, or a thermal diode commonly found on Computer Processors, Graphics Processor Units (GPU) and other ASIC's."

These type of devices typically integrate with an on die thermal diode.

On the issue of BRM46x thermal design constraints, the spec says 125 C. Not 100 C, not 105 C. Looking at the data sheet, it looks like the device temperature is reported via the PMBus and may also be subject to configuration via a configuration file:

"This product is designed with a digital control circuit. The control circuit uses a configuration file which determines the functionality and performance of the product. The Electrical Specification table shows parameter values of functionality and performance with the default configuration file, unless otherwise specified. The default configuration file is designed to fit most application needs with focus on high efficiency. If different characteristics are required it is possible to change the configuration file to optimize certain performance characteristics. Note that current sharing operation requires changed configuration file. See application notes AN307 for further information."

Is anyone having problems with Neptune's shutting down due to thermal issues or is this yet more FUD being spread by haters and envious ne'er do wells towards KNC ?


Thanks for the information on the LM96063 and pointing out facts throughout this thread. I work with equipment where I can measure temperatures 100s of yards away so I don't understand why anyone would thing a small IC on the side of a board is not capable of reading temperatures directly inside an ASIC several inches away. The more I investigate and sift through the postings of people who don't really know the more comfortable I am feeling with the Neptune.

I have no doubt that a better heat sinking arrangement for the VRMs is in the works or could be made. At the least it's an easy thing to modify and I'll get my 12 year old (because of smaller fingers and  better eyes) to take care of it for me. Based on the specs I would like to see temperatures maintained below 100 and preferably 80 to 90 degrees C on the hottest VRM.

Yes: I'm already working on this.  Many things can be improved.

This shit is crazy.... It really looks like they are mining with our machines RIGHT NOW.
I can think of no other way that hashpower could possibly magically appear
https://blockchain.info/pools?timespan=48hrs


Looks like a BFL replay...   https://bitcointalk.org/index.php?topic=659828.0
The drama of it all....  Holy Swashbucklers.


it is simple ...if you hash while you wait we get your 2nd machine the was gonna be compensation (but we don't wait 3 months for it)
then when you get your machine in 2 weeks the above hash goes back to knc farm

if you don't hash while you wait....we (maybe?) hash while we get a machine out but most likely just get you your machine in line

if you have refunded...we never bothered to pull the equip out of the que.we stall on getting refund to you and then take your
equip (prob a head of everyone else) and put it in the PH farm

either way...all refunded machines that were paid for ...are still being delivered to KNC imho just go to the farm

all GH hosting set aside for customers that did not take it go back to farm or did take it go to farm after we stick a tracking number on the  box and out the door to you

they likely have 2x or more machines made 1x is customer orders (all the above) other lot is KNC farm orders ..to be plug'd played
into the old jupiter racks (i bet boards are just snap/screw in and viola ..replaced the other half is what ships to us (specific to
the considerations i stated above that PH farm has priority)

the cool thing about the above is the 'slow' refund rate to customers but the real cash used to get chips for equp for the machines to
go to ph farm asap w/o interuption...even if customers cancel order....no hicups in the pipeline to the PH farm

as far as i think it is all streamlined to get PH farm equip/hast asap..and with likely over ordering with 'not so fast" pre order $$$ it is likely this is working well
and anyone who want so GH farm on the cloud hosting their 'compensation' machine likely already has been figured into the above equation and it to
jumps to the head of the line

with KNC's jump in share of network at the VERY LEAST they ordered 3x the macines (modules) for themselves vs what they put out for customers imho
the stuff just did not pop out of thin air imho

So I was 3 weeks out. I thought the refunds would be shut off at the beginning of June (because knc promised to give everyone free hashing at start of June, which of course was a typical underhanded knc lie/deception).

But I did warn you all in plenty time to start aggressively demanding your refund if you wanted it, or KNC would take your money.

OKBYE

--snip--
So y'all have 10 days left to bail, then KNC owns your cash  Grin
^^^^^^^^^^^^

If they can delay you another 10 days, like I said, you will get hashing the datacentre and they will get your money. There will be no more refunds after 1st June, believe me.

Ring them up and tear them a new arsehole. You have 10 days left to get a refund.

Hi, Refunds are no longer given on any Neptune orders I am afraid. Your Neptune order is due to be created and shipped very soon.
No changes can be made at this late stage.
Kind regards,

Terms of sale knc agreed with batch 1 customers
Quote
All refunds will be refunded in dollars and you can refund up to shipment

KNC - cheap bastards and lying fucks!


Still, this all happened before.

did I miss anything? mass shipping commenced?
been working on p2pool nodes and haven't had my head out of terminal for a week. nodes now in Iceland, Middle East and Europe, if anyone in those regions needs a local p2pool node  Grin

so... nippy's shipping in mass yet? or are they just mining with them all themselves?

er unclear on this whole refund option...I assume (prob wrongly) that if you asked for a refund BEFORE their announcement of NO refunds you will get a refund...OR
are they simply gonna ship your product instead in lieu of your requested refund (some of which are 3 months late)

am I just being paranoid or could they actually get away with withholding your refund $$$ for that long and say 'screw you' and ship the unit at this late date and be golden?

Yes: I'm already working on this.  Many things can be improved.

Thank you for you postings Elenelen. I've already ordered these because of your postings:

http://www.newark.com/aavid-thermalloy/374124b00032g/heat-sink/dp/53R2166

Conveniently these come with thermal tape already applied although I think thermal glue might be the better option. They are a little large; but, that can't hurt.

It is possible that KNC has a better solution; but, obviously they are under pressure to get everything shipped right now.

Currently if you were waiting for a refund before production started your refund will be honoured (at some point in the future)

However you won't get to "go thru all of this crap" as there are no refunds on Titans Smiley
