It must have a smaller compressor.....I doubt it will go as low as -40C
I have a feeling it will work like a good peltier block, mayby down to -20C....
If we see the ECT Prometeia Mach 2 drop in price considerably over the next few months, then mayby OCZ is onto something.....

Ok, I'm obviously missing something here, but how would -40º be any better than -20º?!
They are both so cold that I would imagine you are quickly approaching the point of diminishing returns....
I know a few people that got them just to say that they have them. They don't even OC any higher than I do with my water cooling........... And I'm sure that there are a bunch more poor little rich boys out the the same way.

-40C will be WITHOUT any cpu on the block.....so that would be -20C under load
If it does -20C without a cpu, then under load it could be near 0C
I doubt 0C is enough to add ALOT more vcore.......If it was -20C under load then I'd think about adding 1.7v+ vcore........
We'll see when it comes out.....
I need to stop looking at this thread......I don't need phase change, can't afford it, but it's soo tempting!! LOL

Ok, yeah, but even going from 0º to -20º or even -40º, is there really that much of a gain?! I mean, you can argue that maybe the atoms and stuff in the silicon are closer together and the electrons fire faster or something when it is colder, but how much difference can all that really even make??
A chip should always scale well with added vcore.....If it doesn't the chip is a bad design and shouldn't have gone into production......The problem is that, as you know more vcore can/will kill a cpu....
If you can hit sub-zero temps you have a better chance of getting good returns for added vcore....
The above link aslo explains how vcore alone will/can kill a chip, even with sub-zero temps.....the Intel guy says vcore is waay more dangerous than heat.......
Nordic hardware done an article Overclocking Athlon 64 FX-57 It gives you an idea how a chip scales with lower temps and more vcore.......
In the end.....I wait for someone else to buy this and let them be guinea pig......Or if I ever decide to get a Intel preiser chip :p
So it just basically adds the possibility to increase vcore, to eventually get a better overclock. But, like you said, you are still increasing the vcore to dangerious levels, no matter what the temperature. I guess if you have that much to spend on a cooling system, you don't bother with keeping a chip long enough for it to get burned out with too much vcore
I just didn't know if there was more to it than that. Thanks ken
that's all it is......the further you go from stock the bigger the risks.....sub-zero cooling just allows you to go further....(increasing risks)
That's why I'm unsure about the whoe phase change thing....OC'in is one thing....it's a calculated risk....I'm also a greedy OC'er......So if I went phase...I know I'll kill my proc....
I'm conservative in OCing, and I figure if I can get at least, say, 300-400 MHz OC out of a chip, I'm happy....which I guess is why I'm only deciding on high-end air for now (XP-90C w/ a Delta high-flow fan).....when I get more greedy, I'll get something more expensive, lol

Your not infected yet!!! OC'in is a bug...It eats away @ you....slowly but surely it gets you.....It's fun....and doesn't have to be expensive, no wait my bank balance says otherwise.. lol
haha, just ask Joe....he got so much so that he wanted to reduce his temps by removing the IHS on his opty, tsk tsk, killed it deader than dirt too, rofl
yeah I'm not infected with the OC bug yet, but I think that'll change when I decide to OC the video card.......I'm a sucker for hellacious eye-candy, lol
Something to keep in mind.... the temp sensor is nowhere near the head on these things..... its back a ways, so the reported temperatures are not accurate and can be off as much as 20C.
If they are saying 20C, then you need to know if thats the BIOS reported, or accurate temperature..... or if thats the temperature the unit is reporting.
Well my prescott not overclocked with the huge heat pipe i have still runs at 40C. higher when under load from gaming. Its an intel, so i expect it to run hot. Not, say i spend 300 on this unit, and get my temps under load to 0C, then id be happy. then i would consider OC it.
I personnaly dont care about -40 vs -20. I just want to get the temp on my system down, so i can pull a few fans, and but down the aircraft engine sound i get from the lower right of my desk.
OCZ informed me that they have these units made and are sitting in China because they can't find a way to ship the gas legally to the united states from China... Just an update if anyone is wondering what is going on with these suckers.
And I'm sure that there are a bunch more poor little rich boys out the the same way.
