Hmm, didn't see a thread yet so here you go...
No review/benchmark so don't even bother clicking if that's what you're looking for.

MOAR COOLING!!!

I could see that heatsink fuckin shit up, with the density of all those fins combined with the fact that the aluminum version already weighs 750 grams about. Also going to need high speed fans to move the kind of heat that copper can absorb.
 
I don't know if that will make a difference in cooling. Copper isn't as good as aluminum for dissipating heat, thats why heatsinks fins are usually aluminum. Copper is better at absorbing heat, thus why it is used for the heatsink base, and heat pipes.

I'm unsure if I'd want all that weight hanging on my motherboard.:confused:
 
Mmm...CU! Luv it!!! Looks sooo sexy! I must agree with Simpson5774 though that the tight fins on that model will need a good fan fo sho! Weight 'shouldn't' be an issue as long as the mounting is proper for such a beast.

IMHO the Ninja did it right with the wider spaced fins...

That would be a nice mantel piece, you have to admit. It is a beaut!

I see this brought up a lot and I've never seen any proof of it. Copper heatsinks tend to perform better than aluminum. IIRC Aluminum is used for a few reasons; namely, weight, cost and ease of manufacturing.

I think heatpipes have largely equalized the performance of heatsinks now vs years ago when heatsinks were just metal fins (remember those days?) but I haven't seen any reason for the above claim ever.

If copper is better at absorbing heat, it would be at a higher temperature than the surrounding (ambient) air and thus dissipate heat to said air more quickly as well. At least that is what my terrible understanding of thermodynamics is telling me. I could be wrong.

That's actually not true(no pun intended ;)). That statement has been spouted in lots of places, but it's not actually true. I actually believed it was at one point, but the fact of the matter is that copper's higher conductivity of heat actually makes it better at transferring heat to air than aluminum. I don't blame you for believing it though, there are a ton of misguided people out there who repeat claims like this without actually researching it to see whether or not it's true.

That said, there really isn't a significant benefit to using all-copper heatsinks nowadays since most of the heat transfer is done by the heatpipes and base which are almost always made from copper, so the actual differences caused by the poorer conductivity of aluminum don't affect overall performance as much. See the Scythe Ninja Copper as an example of this.

PS: That AXP-140 looks quite interesting. The copper TRUE on the other hand probably weighs a ton, so I wouldn't be too enthusiastic about sticking one of those in a PC(not that it wouldn't cool insanely well, of course).

Beat you by 10 hours; winnar!
(just kidding).

Yeah I see people say that a lot; I seemed to remember the reason aluminum is used more is cost and it was easier to extrude. Now that everyone uses heatpipes copper vs aluminum doesn't even matter and I'm pretty happy with my scythe ninja (aluminum).

Nice to see technology advances making a difference... hard to imagine where we'd be without heatpipes.
 
i would love that copper TRUE, but as already mentioned... that would be some SERIOUS weight !!
 
Damn that thing's sexy. But I do agree, it's gotta weigh a crap-load. Rigging up a support system to the top of the heatsink just so it doesn't rip the mobo in half FTW.
 
If I remember correctly (it was 27 yrs ago so maybe not) in high school auto shop, it was claimed that copper radiators were a better choice for heat disapation than was aluminium. Wouldn't that also apply to heat sinks as well? Even though they have been traditionaly aluminum?
 
Yes. As I have already explained, the idea that aluminum dissipates heat more effectively than copper is a false myth.
 
The weight of that would make me scared to move my computer ever, I don't know if the added weight and cost is worth the what 2 degree (total random number btw don't flame me on that) drop? Just admit it, if you want the bling - go for it
 
just so everyone knows, they will not be making the that

"Seems we did not make things clear yeaterday, beceasue today a Thermalright rep expains that company actually have no plan for producing Ultra 120 Extreme full cooper version. The cooler in this pic is only for ComputeX display only. It is said that the weight will broke any mobo so they won’t debut such a product."

Why does he keep saying cooper? It's COPPER, dammit!

You dont know that for sure. They couldve chopped up someone named Cooper and made a heatsink out of bodyparts. However due to a shortage of Coopers (who wanted to be chopped up) they could only afford to make enough for their computex display.
 
Mmm, big pieces of copper give me wood. But that's gotta be a heavy motha.
