Nice to see you totally ignored how I proved TDP in that test was 175W 75% of the time.

Um, no you didn't. A screenshot of a graph with no Y axis labels proves exactly nothing.  Especially since it doesn't even show the temperature going up by more then 70% over 41C, yet the article claims the temp was 79C.

It doesn't particularly work that way in heatsinks, that cooling power is higher at 90C. The limit of heatsinks is the immediate transfer of energy from the base plate to the cooling fins, where THEN the cooling is increased. Heatpipes max out pretty quickly,

Every part of the heatsink moves energy more efficiently when the thermal gradient is higher. Heatpipes, fins, etc. Thermal conductivity is measured in W/m^2 K because as temprature differences increases so does heat flow. It's a straight linear relationship.   Nothing can "max out" on heat transfer, unless it burns or goes through a chemical reaction and turns into another substance. (like from diamond to graphite)

Seriously, you're just proving over and over again you have zero clue when it comes to thermodynamics.

Dear Non Engineer,

You don't have a clue about any of the technical information in this thread. Again you're just dismissing the logic spelt out line by line with the sentiment "they must be getting it right".

tldr: Greed/desperation > logic.

WTF are you talking about?  You haven't done any "engineering" or said anything "logical" all you did was post a random screenshot of a graph with no labels and that doesn't even match up with the other numbers and claimed.... something.

LOL so much fail in this post. I linked you to an impartial review, and you're dismissing it as if it was specifically written to backup my statement. Yes, that graph is definitely wrong isnt it *sigh*

No, it doesn't work that way in a heatpipe based super tower. Heatpipes do max out, it gets to the point where the working fluid can't condense again.

As I've said many times, you're really clueless and its not worth arguing with. You turn real science into "it must be a shill". Leaving you ignored now.

This is not good for my Chi... Yifu
I dont recall that, I received the newsletter to my e-mail address and I thought that it said both 12V & 5V supply.
Even if it only said 5V Anyone would have thought that they had made a typo otherwise they would have been shipping ESAB Welding sets instead of Bitcoin miners,  Oh hang on  minute, Isnt ESAB Swedish?    Wink

Its quite obvious what the 5V supply is for and to see so much confusion in this thread is quite surprising.

Initially the release said ONLY 5V (as in no 12V connector) which is what resulted in confusion for the first half of the thread.

Its been said before but it probably needs saying again,

5V is for the RasPi
12V is for the mainboard

cheers,
kev

+1

Well ORSoC's own made Linux based equiv. of the R Pi.

I seriously doubt they are going to "make their own RPi."

They might buy RPi's and slap their logo on them, but I don't think they are making even a "custom" RPi for this--if so, where is the information in regards to them stating this?


When I said RasPi, I was (as Bitcoinorama pointed out) referring to any generic linux based mini controller board which, If you have been listening to KNC, it is what they hinted they would be using so that the Jupiter is literally a plug and play and walk away device. I dont know what is so unbelievable about them developing such a device if they wanted to, it would cost under 10 bucks and they would prolly use it in all the models.
Go back and read the news releases if you want the "information"

Its quite obvious what the 5V supply is for and to see so much confusion in this thread is quite surprising.

cheers,

Shipment is supposed to start very soon, in June I was told in August they would present a working ASIC prototype - any news on that?

Nope, they were just joking.  Ya know, those crazy Swedes

Actually yes. It's already been proven that the chicken came first Cool


Uh... that's not really what people mean when they say "which came first, the chicken or the egg", typically they asking whether "eggs" or "chickens" came into existence sooner, in general. not whether an egg starts growing before the chicken embryo inside of it.

KNC is looking good so far IMO. Can't wait to see the PCB samples next week...

I cant tell if they paid you or you're just dumb

Who cares, if it heats up I'll mod my freezer lid for the wires and throw it in there

That would be a bad idea (freezers not designed for continual heat loads).

Still I would expect (hope) that KNC already thermal load tested the cooling equipment.  They don't need chips for that, just an test heat source (heat plate).  They should be able to properly measure both chip and overall system cooling without the need for any chips.


well they will be arriving after the summer, so in the winter they can go in the garage!!

I dunno, I run an Arctic A30, with the supplied fan (which only does 1100rpm full speed) cooling a FX8320 overclocked to 4.5GHz.  That chip pumps out a LOT of heat.  The fan is slow.  Adding a decent fan would obviously cool the heatsink a lot more than the silent one supplied in the box.

I think their ASICs would need to be pumping out a ridiculous amount of heat to overwhelm an A30.  It's a ridiculously big unit - mine is hard against the side panel of my Fractal Define XL case, that's how big it is.
Which on 100% theoretical OC'ed load is still only 150-175W. But actual games/other uses never 100%. Now more than double that heat output.

You haters think the diff is already too high to run it more than 5hours once we get it so who cares about some short term rigging we'll do while it hashes

people seem to forget the whole mars prototype they made, took pictures of, took video, did an open day with, showed it hashing, pcb with the mistake "bitcoin makes the world go around" on it. what more do you people want, jesus.

You are practically inviting a comment from eve here, you do realise that?

Ok, I do want to see pictures of the PCB.  That would relieve further doubts.

I DO have a KnC preorder and will take any additional information that puts me closer to a solid delivery in September.

Of course I have my doubts. Let's be honest though, would you bet on some of these other companies over KnC? CoinTerra? Hashfast?  Seems like KnC has been the most forthright in this process and they have followed through on things they say publicly thus far.

somebody please put down this dog.
Again, rather than actually refuse my claims directly you just dismiss them nonchalantly. No problem, I don't have KNC preorders. Ignore away.

When you see a retard do something retarded, you don't go and try to correct him. You just snicker and walk away.

Hats off to you sir! you just made my day.
