KNC just posted pics of their case, PCB samples coming next week \o/

[ASIC-K]

Wait wait wait wait wait... that's they're Jupiter cooling? ROFLMAO. Those heatsinks are rated for peak of ~140W, not 250. And they think they can exhaust 1kw of heat with 2 standard 120mm fans?

My 1x250mm 1x200mm, 5x140mm and 2x120mm case was struggling with 800-900W. I told you those thermal simulations were really, really wrong.

Sorry to disappoint you guys, KNC lives in the clouds.

You are obviously clueless, I suggest you check the specs of the components before pretending you know better.

thanks for this. yup. 320 watts max. well within limits.

We want to see the Asic Chips.

Heatsinks are Arctic i/A30 which are rated for Max. Cooling Capacity 320 Watts
You are some sort of an expert, aren't you?

Your move do·gie

Here's a proper avatar for you as well.

Uh, no.  As other people have pointed out, they're 320W each.

I've worked with 100s of desktop based heatsinks, but whatever go ahead. They still never explained their simulations that were FAILED.

Enjoy your vapourware/house fire.

Oh, hundreds huh? But apparently you were totally wrong about the specs of the Artic A30...

LOL at the desperation in this thread, people going to be sad when KNC runs away.

It was a larger model than I thought as I just skimmed over the pic, but just try running that at 320W 24/7 LOL.

So now the chip is 320W instead of 250W? When did that happen.

Apparently it's really difficult for you to keep numbers straight in your head.

It's not desperation, we're basically laughing at you... .

You're saying its rated at 320W, I'm saying its not. AC are renowned for overstating their numbers. Just look at the CFM on that 12CM 1200RPM fan ^_^

[DobZombie]

All this arguing.

I'm getting BFL flashbacks...circa November 2012

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

Cool ..then put your money where your mouth is !!!

http://bitbet.us/bet/472/kncminer-will-deliver-asic-devices-before-october-1st/

Or are you a little biatch ! 

we did, by buying miners!!  This seems more like a hedge bet anyway

Exactly, I already bet on the KNC horse with a $7000 pre-order, I'm good. Plus after bitbet.us totally screwed up the "BLF ships in April" bet I'm not betting a single satoshi on that site.

So what you're saying is: you actually can't tell the difference between the fan and the chip? The fan is 320W, but the chip is only 250W, or less (probably a lot less)

Also, trying to argue that KnC won't ship because Artic is straight up lying about their heatsink specs is moronic.

You have to types of wattage :

• Electrical watts
• Thermal watts

If a chip uses 250 of electrical watts and gives 250 of thermal watts, that means you have a chip with no hashing power.
The cooling capacity of the fan (320w) is the amount of thermal watts it can deal with. Not the amount of electrical watts, consumed by the chip, it can deal with.

There will be no heating problems. Personally I think one chip will not give more then 125 thermal watts.

Not sure if serious?

All (or 99.9999999% so we can just say "all") electricity used by an electronic circuit is converted to heat.
A chip does not real "work" (in the physics sense).  Law of conservation of energy.  If 100W (electricity) goes in then 100W (heat) comes out.

LOLwhat?

[dogie]

Yeah don't know what that was... anyway, I was remarking that I don't believe the heatsink to be able to dissipate 320W of heat - as they claim it to be able to. And as you can see, the fan CFMs just don't make sense. If it was really 70+ @1200rpm, it would be the best on the market, and not the £4 retail it actually is.

[Ytterbium]

This 120mm fan does 74CFM @ 1300RPM.   It's $9. And actually it's the exact same fan used in the heatsink, as a separate product. Here's another fan from another company 1500RPM, 71CFM, $12 and this one is 1400 RPM and 74CFM, for $11.50.

Seriously dude, WTF are you talking about? You're obviously wrong and clearly don't know that much about fans and heatsinks, as these specs are clearly possible and readily available.

Each one is about $40 on Newegg, btw - so that's $160 on cooling if you bought them retail. plus the main case fans.   And even if the specs were off, it wouldn't matter as they're actually overpowered for the expected thermal output.

[ASIC-K]

hes just trying to sound like he knows what hes talking about (which he clearly doesnt) and is obviously trolling. just ignore him.
