Or do they just just type anything and hope for the best? :stick:
OT: Funky looking cooler, can't wait for some reviews. Also, just to reiterate the point, carbon fibre is completely different from carbon.
Dont bash OCZ for trying new things with technology, if every one had your attitude we would all still be using CRT's. Even if some thing is worthless when invented it may spark new things.Quote:

lol i was gonna say "if this cooler actually beats tower 120 or ultra 120 extreme, then hell yeah ill buy it"Quote:

However, the question is how fast heat transfer coefficient draws out of the cooler using silent fan + copper& water cool? Another thing: by looking on the picture, not sure what they mean about “carbon core”. Is it just a thin sheet of carbon foam attached to copper, and then its thermal diffusivity won’t be effective. But if it’s the whole core of carbon foam (except the copper fin for water cool) then it may help. Keep in mind that carbon foam is not cheap.

My question, how would this perform better in your oppinions, considering the IHS and fins are copper?
Maybe they develop a graphite thermal paste - shouldnt be hard to do.

By the way...the google search was made to determine the if the thermal conductivity of graphite (not specifically foam because it had not even come into the thread at that point) in response to this post:
"Nah look at the 2nd pic, top right. The base is clearly shown in copper, render, actual, artist's conception, whatever. It can't possibly be carbon, the thermal conductivity of carbon sucks compared to copper."
How about I go back to forums where the goal is not just bashing newbies.
I read years ago about pocofoam which was an interesting but expensive idea. Is this an extension of that?
yeah i know it's the inq but it offeres the best explanation of the cooler i can find thus far:
http://www.theinquirer.net/default.aspx?article=38294
"You end up with .5 square meters of surface area for cooling so the Hydrojet can dissipate 350-400W of heat with very low noise."
carbon nano tubes it sounds good to me but as always pending benches for opinion
Folks, ... The proof is in the pudding .... just wait till review pop up ! Then start arguing ! :D
Is this coming out within the next 2 years? What ever happened to the OCZ phase cooler??
While the ligaments do indeed have such thermal conductivity, the material as a whole does not, it is more than just aligned ligaments. The link you provided shows a bulk conductivity of 135 w/m*k in one direction and less in the other.Quote:

Even *if* the base is made of graphitic foam and outperforms copper, this monstrosity will still be held back by the fact that water CONVECTION with that little water is just not enough of a force to effectively cool a hot CPU. Add on to that the fact that *at best* this uses a single 120mm fan. Regardless of what it's made of - it could be made of pure diamond for all I care - the maximum amount of cooling power it has will be limited as well by that one fan. You can only remove as much heat as you can put into air coming into/out of the device, and the more air you put in per second, the more you heat you can transfer. A single "silent" (read - low CFM) 120mm (hopefully) fan just doesn't pull in enough air to make this the best thing since sliced bread, especially when you consider all the restriction the air is going though. That's going to slow it down even more.
Again, I hope that the OCZ ocgineers have looked at some of these issues and designed them out... but there are certain facts this in this universe, and until I see some info that says otherwise, this thing just won't be the best thing out there.
I'm not saying it won't work at all, it will. The thing is though that unlike many popular heatpipe soultions today who can achieve a minimum temperature of around 20 degrees C (because that's the condensing point for many heatpipes, they simply don't make use of the heaptipes themselves beyond using the copper tubing as a conductor, making no use of the liquid inside), the *minimum* temperature attainable by this design will be by definition of the engineering, higher than that. Now, it may very well be that if the target minimum is around, say, 40 degrees (complete guess without a better glimpse of the inside) that it is very effective at holding it near that temperature, but it just DOES NOT have the capacity to go much lower.
Why do everybody think it is "foam"? Maybe it is similar to the graphite found inside pencils, but molded as a base.
If they would use graphite base to "speed up" the heat transfer to the copper fins, the watter probably is used to further up the potential of the cooler even though it is contained in there, they surely tested it with air and found that water is better.
Funny thing is that we are here discussing it while that OCZ guy is reading our post speculations and laughing it up :D
Edit: I just saw Inq is talking about nano tubes... Please is no news big enough for them... How much would that thing cost if it was using nano tubes... really inq, ccccc...

I read it wasn't water at all, but it was oil, and there is a pump in there etc.

Very interesting read indeed.
So, if a graphite based material is such a good heat conductor, why we don't have a carbon thermal paste already ? Would cost much less than silver !
Probably because graphite doesn't fit in crevices as well.
Actually Carbon in the correct form has excellent thermal properties. Just look at Diamond.
I can't wait to see how it works when it comes out.
If they do indeed use micro tubes and a pump of some description (even something thermally-powered), that is good. Certainly better than had been suggested by the first review of it (not that they knew I would assume).
Still, my statement about heat removal capabilities being directly related to amount of air that passes through remains, as does my assertion that while this may be very capable of holding a CPU to some temperature, that temperature will be decently above ambient (which can still be fine for a CPU) if only because the closer to ambient you get the less heat will be able to transfer to the air in the same amount of time.
If I understood how the inq described it, it works like this: carbon pickes up the heat then transfers it on to the water tank. That tank has copper fins partly immersed in it while the other part of the fins are cooled by air.
One issue could be surfface area of the graphite base immersed in the watter...

will be waiting for results before saying that it might be bad or good
