Something is wrong here with this simulation. Its a side view of the board at the bottom, with package and chip slightly above, with a 4 heatpipe heatsink. The left, blue side is showing an ambient intake of 25C, exhausting at ~50C.
Now, look at the chip area; its deep oranges at best. Their own simulation is telling us the chip's heatspreader [not even the chip itself] is somewhere between 125-150C. I don't know a consumer grade chip that gets even close to these temps, nor materials creating using conventional techniques that would withstand 24/7 at these temperates.
Its hard to tell without a larger image but it looks like an auto scaled legend, so its reporting a spot temperature somewhere on the chip of 223C. I am not aware of the limitations of the exact simulations they ran, but if mine came back and showed that I would be weeing myself.
tldr: Either that simulation is made up, fake, wrong, set up horrifically - or the chips are running @150C+.
Exactly. Even companies like AMD or Nvidia, with the best thermal engineers and ASIC designers on the planet, barely manage to approach 200-250W consumed by the GPU ASIC chip only (even then, a good 50W+ is consumed by the rest of the card, so the GPU ASIC itself is closer to 200W, not 250W).
KnCMiner is so ridiculously underestimating the complexity of their technical choices... There is absolutely
no way they will ship a ~250W 100Gh/s chip (their claims) in October 2013. Mark my words.
It is mind-boggling to see the number of people who accept KnCMiner's claims of feasibility without blinking an eye.
KnCMiner will either spectacularly fail to deliver anything. Or they will have to underclock their chips and increase the number of chips per device to match their performance numbers per device (like BFL did with the Single SC).
