IT'S FINALLY HERE!TRUE COPPER!!!!
I have a bunch of pennies in a large jar in my closet and they are true copper.
Is that really the best material for fins? Higher capacity but lower conductivity. Plus the board-bending weight.
well they cant cool CPU so AH! there is the difference!
copper is the best conductor better the aluminium.
When will they make a pure gold heatsink?
The following materials are commonly used for heatsinks:
* Aluminum. It has a thermal conductivity of 205W/mK, which is good (as a comparison: steel has about 50W/mK). The production of aluminum heatsinks is inexpensive; they can be made using extrusion Due to its softness, aluminum can also be milled quickly; die-casting and even cold forging are also possible (see part 2 of this guide for more information about production methods). Aluminum is also very light (thus, an aluminum heatsink will put less stress on its mounting when the unit is moved around).
* Copper's thermal conductivity is about twice as high as aluminum - almost 400W/mK. This makes it an excellent material for heatsinks; but its disadvantages include high weight, high price, and less choice as far as production methods are concerned. Copper heatsinks can be milled, die-cast, or made of copper plates bonded together; extrusion is not possible.
* To combine the advantages of aluminum and copper, heatsinks can be made of aluminum and copper bonded together. Here, the area in contact with the heat source is made of copper, which helps lead the heat away to the outer parts of the heatsink. The first heatsink for PC CPUs with an embedded copper piece was the Alpha P7125 (for first-generation Slot A Athlon CPUs). Keep in mind that a copper embedding is only useful if it is tightly bonded to the aluminum part for good thermal transfer. This is not always the case, especially not with inexpensive coolers. If the thermal transfer between the copper and the aluminum is poor, the copper embedding may do more harm than good.
* Silver has an even higher thermal conductivity than copper, but only by about 10%. This does not justify the much higher price for heatsink production - however, pulverized silver is a common ingredient in high-end thermal compounds.

3 kg....omg (hope ppls boards dont break)
It looks awesome though. almost can put it in a modern art museum (better than most other stuff
)
Too bad i might go H20 cooling
Did someone say that AL is a better conductor than CU? I hope I'm reading it wrong.
i think i was under the misconception that copper retains the heat and cant dissipate it as fast as AL that's why they are CU base with AL fins
anyone know what i am talking about and want to clarify?
also i envision horror stories of those snapping of mounts and busting vid cards or things of the like
@ silverion77 dont most people get upset they cant go h20

Copper has significantly better thermal conductivity the aluminium (about 30 - 40 % better)
The reason that they use the copper (a thin layer) at the base of cheap coolers is that its the best thing to take the heat from the cpu and conduct it to the fins. The only reason it isnt used anywhere else is cost.

Right on the money.
With the surface area of the fins and the copper itself, I can't wait to see some test results using this heatink!
3KG??? Holly c**p!!! No way in hell i'm putting this over my 4870!!
^^ Cinder block suspended by fishing line = same result.
it was revised to 1.8 kg

That was shown at Computex08, but it was thought it would not be released because of the weight.
[ Hardware.Info ] - [Computex08] Thermalright launches new CPU coolers
| Quote : The company also showed a version of its Ultra 120 eXtreme made entirely out of copper. Though this cooler would most likely have excellent performance, it will not be released because Thermalright reports the motherboard would crack under the heavy weight. |
All this talk of cracking motherboards....whats stopping somebody from turning their tower on its side??
i like my side... =[
but yeah copper cant dissipate heat as fast, unless of course, it has an insane surface area!
i, myself, am waiting for the danamics lm10 liquid metal cpu cooler... its supposed to be godly against these air coolers, and rival the best watercoolers too... it was supposed to be release q3, but since they're getting so many requests from companies [hopefully one is newegg (^-^)b]
that they know they're gonna be in backorder, so they're upping the production...so q4 it is =[

I googled that cooler, and it sounds very interesting! I wonder how much it will cost....
re: non-air coolers: the Coolit Pure has a price point of $129, that's the one to get, imho.
re: all copper heatsinks:

i dont think that skinny ass can cool a Q6600@4Ghz.
i think suspenders will be included in the box with the TRUE Copper!haha
They need to make a pure Silver one. Pure Silver is a better thermal conducter than Copper.
if you are willing to pay im sure you can order one from them directly

I'm telling you, gold is where it's at.
Gold is the 3rd best conductor. First is silver, then copper, then gold. I wonder how much more heavy it would be if it was silver or gold.
actually, diamond is the best heat conductor.
Your right Diamond is... Think they need to make manufactured diamonds now see this chart to see the difference in thermal condictivity. We need to move from copper to the Diamond era.
Aluminium 237
Gold 318
Copper 401
Silver 429
Diamond 900 - 2320
Next question would be forming the diamond into a solid design such as what we are used to seeing. Not like we can liquidate and make a mold for diamond to form how we want. over 2x the thermal capacity of thermal conductivity. Thanks eklipz for mentioning diamond.
Why do I need a car, I need a diamond cooler.
thanks for clearing that up for me lameness
200K for a CPU cooler anyone?purely diamond made!LOL
how to address heavy weight heatsinks.... didn't they do that with the p4? but that was by design by intel, and quite proprietary. in theory any back plate will work with the standard 775 mounting holes as long as the threads are good. soooooo... in order to address the mounting issue, you just modify the back plate
Options include -
1. a bigger expanse spreading the load out to neighboring stronger areas such as all of the motherboard mounting screws where there will be minimal to no flex.
2. a leveraging device that attaches to the studs off the mount through the board, that lever goes vertical one way or another and also can attach to the case to limit flexing.
3. direct suspension of the weight of the heatsink via bungee, or card slot related adjustable bracket.
4. hold it with your hand while computer is vertical.
5. extend the studs of the heatsink so they make contact with the chassis to avoid some deflection (leverage will still exist on this one, but it will be less)
6. This would be the custom solution http://i268.photobucket.com/albums [...] 0_0010.jpg
Weight wouldn't be an issue if you had a non conductive material that would be like a foam like substance to carry the weight, just have to make sure you don't flex the board and I think it would carry anything you put on it.
200k for a heat sink that would be one of a kind made of diamond would be kewl, last longer than a lamborgini, and wouldn't cost anything to operate, and should also sustain its value too.
I wonder what the molecular weight of diamond is in comparison to copper, gold and silver.
lol actually no it wouldn't last as long as a lambo, once the socket changes, YOUR SCREWED
lol agreed...^^
Also how do u compare Diamond to a lambo?!?!
Any car, as soon as u sit ur butt in that seat and turn on the engine for ur first drive, the resale value drops and continues to drop.
Diamonds actually go UP in resale value lol
^owned!LOL better luck next time eklipz330!
well u got 2 choices w/ diamonds
a) put it on ur current/future wife's finger
or
b) use it as a awesome heatsink for ur computer LOL
Ill take the computer
U dont need fancy ones, just get off colored ones. Not as expensive
how about crystal?
Highest thermal conductivity of any known material is carbon nanotubes.
^=.=|||
how come frosty says the thermalright ultra has less performance than the ultra extreme? confused...
cause of the convex issue of the extreme
The Extreme i believe is still #1 but Frosty refuses to change hardware = lapping that horrible base of the extreme
carbon nanotubes now that sounds really cheap. Carbon is in everything.
sure the carbon part sounds cheap....
but the nanotubes part HAHA
ever heard of carbon fiber (not the same thing) but its still expensive same for nanotubes.
err carbon fiber is stong and light... i have a feeling its completely hopeless at conductingh eat though..
exotic metals are far from ever happening. Currently we see copper, aluminum, heatpipes, and fans. That sums up all current cooling options, but what is the next evolution for thinking outside the box. how can we dissipate 200 watts of heat energy using copper or aluminum? maybe a precharged r-134 circuit? Big pieces of metal aren't the answer.
i just carefully busted open a coolermaster gemini II heatpipe to see whats inside, to discover a powder substance. Anyone want to explain that one? perhaps it was filled with argon or some other inert gas?
i thought the heatpipes had a liquid with a low boiling temp so it evaporated up the pipe to get cooled by the fan and heatsink and then condense back down to a puddle at the bottom of the cooler..
yea, that is whats inside their (sort of liquid cooling in the pipes)
but a powdery substance is sort of weird, unless it reacted once u opened the pipe

Cu has much higher thermal conductivity modulus than Al. it transfers energy (heat) faster, be it absorbing or dissipating.
the reason Al seems to be better at dissipation is that it doesnt absorb nearly as much energy in the first place. but the copper is faster at collecting and dissipating, which is goverened by the same property (IS the same thing, only in reverse). dont let anyone tell you otherwise.
aluminum is used due to its cost/performance ratio. and it is very light.
