Thermalright Ultra 120 Cu Limited Edition up for Grabs Next Month

I highly doubt this, water cooling can stay good near ambient, but cant got below it. Nor can aircooling, and nor a combination of them.

Anyway, looks nice. But that heat sink is really only practical in a horizantal installation. Maybe your motherboard wouldnt break right away, but with the varieing temperatures from CPU load/idleness, not even to think about the added ambient temperature fluctations... Sooner than later it will at least get some damage there.

Anyway... sounds like a nice solution for a HTPC and passive cooling (or at least very low airflow then)

Actually, yes this type of watercooling will go below ambient. I really don't feel like explaining it so here's a link that explains the concept: http://forum.overclock3d.net/showthread.php?t=3856
The wikipedia explaination: http://en.wikipedia.org/wiki/Bong_cooler

There are many other sites out there too that will show you just about any way possible to make one of these bong type coolers. When setup properly, there is no radiator out there that would beat one of these (since no traditional radiator will ever cool below ambient). The only problem is that it is an open system so biocide is necessary but with the evaporation taking place that biocide will also make it into the surrounding air, that also means you always need to keep a close eye on your water levels.

i wanted to post the answer to this no fun

You all need to shut up arguing about copper vs aluminum. Wait till the freaking cooler comes out and someone compares the two. If the all copper one wins or the aluminum one wins then you have your answer to which material is best as the two versions seem the same design minus material differences.

Yea, I can't wait to see some benchies. I doubt it'll make much of a difference, maybe like 1°C. Plus there's only gonna be 3000 made so the chances of getting one will be very slim. I bet they'll be about £75 here in the UK.

Yes, but in other coolers the materials are not reacting with the air or going through any physical reaction or phase change.

And the water is reacting with the air. Actually, the water vapor in the air, is reacting with the liquid water. Evaporation is actually caused by a reaction of the material to itself. The molecules collide(react) with eachother and transfer energy, if one gets enough energy to change state, evaperation happens. Now, the water vapor in the air is also reacting with the liquid water. As the water vapor in the air collides(reacts) with the liquid water, it often takes the energy from a molecule that would normally have enough energy to change states. This is the reason that water evaporates more slowly when the air is humid. There are more water molecules in the air colliding with the liquid water molecules and preventing them from changing state.

I had a lot more written down then I noticed this is becoming more like a book than a thread, and yeah the statement that started this way back with chron about aluminum magically keeping things around it cooler than ambient.... well we just found a way to cure any thought of global warming So since the start I'm in agreement with you, there is no metal alone that you can place on your cpu that will take the temp below the ambient temp of the heatsink and air which is why I started with I was just being a smartass and showing a way of going below ambient with water and a fan. In a very simple way, it's just a poor man's phase change cooling system.

Thanks, haven't read that article on here before. Pretty much all anyone needs to know for it.

I refuse to be impressed by any cpu heatsinks until I see one specifically designed to to fry food when under load. Then I can fully bring my girlfriend into the realm of computers because she loves cooking.

Thanks, I hadn't seen that one yet

I saw one with an xbox360 where they used the stock heatsink without any mods, just let the egg go through all the fins and it fried in a few seconds I wanted to see something more like what you posted though, where they actually make a more "practical" frying surface.

 

[eidairaman1]

watch as they release a entire line of these copper coolers.

 

[eidairaman1]

3kg OMFG! I thought the Alu one was heavy. Bye bye mobo! I guess this will only work in desktop oriented chassis? Even then wont it fubar your board? Gonna need some sort of packing to stop it bending your mobo something wrotten.

Isnt copper heatpipes and Alu fins the best combo though? Cus alu is better at dissipating heat? I would imagine this thing will be damn expensive.

I didnt buy the 120 cus of its weight but thats ridiculous!

Aluminum was only selected because its more abundant, and weighs less, thats why many vehicles use aluminum for their radiators. Copper conducts/dissipates heat faster.

 

[Hayder_Master]

more copper more cooler , nice and cool , but only tip is why it is not touch pips

 

[DrPepper]

Higher density = better transfer NOT better release. It retains heat better due to being more dense than Al.

I tell you what. We'll heat a 12 guage piece of Cu and Al wire up to 200F and them cool for a few secs. Which wire are you going to grab?

That's what I thought.

You were the one who said it dissipated it faster and I wouldn't grab either that would be stupid. The Al would take more energy to heat upto 200F than copper. I don't even know why I bother arguing about the properties of copper and aluminium on the internet, it's not like its something you can have an opinion on.

I agree with you. As I quoted before, the metal does not care if the heat is coming or going. It's a thermal conductivity constant for a reason.

EDIT: Meh. no need to overdo the theory behind it.

 

[lilkiduno]

well i think i would want to buy one just to have it, even if i weren't to use it i would like to have a full copper air cup cooler

 

[Deleted member 24505]

I was reading a thread on XS about this,i think its more like 1.5kg,not 3kg.

Whoa, interesting. In that case, yes you're right. It's a bit like human body and sweating obviously, but then different

I am so sure about that.

I lived in Phoenix Arizona one summer, we had what is known as a "Swamp Cooler" on the house which used water evaporation (basically a big box with water dripping through fiber mats and a blower), and even when it was 45°-50° outside, it was a comfortable 23°-25° inside.

That's quite amazing indeed.

Some interesting facts for copper and aluminium: copper weight is 8.96 g/cm3 , aluminium weight is 2.7 g/cm3. This means that copper is 3.32 times heavier then aluminium and "yes" it is possible a 790g Thermalright Ultra-120 eXtreme to weight 3 kg in "all copper".
It will take 3 kg metal to make a single copper cooler and only material will cost 3kg x 8 USD = 24 USD. When it is made from aluminium the price for the metal is 0.79kg x 2.5 USD = 1.98 USD.

well its about density aswell, more dense a material it is the better a conductor it will be.

 

[DrPepper]

Arn't humans quite good conductors of heat

 

[Zehnsucht]

well its about density aswell, more dense a material it is the better a conductor it will be.

Copper
Density: 8.96 g/cm³
Thermal conductivity : 401 W·m^−1·K^−1

Lead
Density: 11.34 g/cm³
Thermal conductivity : 35.3 W·m^−1·K^−1

Diamond
Density: 3.53 g/cm³
Thermal conductivity : 2000-2500 W·m^−1·K^−1

The thermal conductivity is dependent on how the atoms which build the material in question interact.

 

[theJesus]

If I made money faster than I could spend it, I'd commission myself a custom diamond heatsink

Is the thermal conductivity still awesome sauce if it's a synthetic diamond?

 

[DrPepper]

It should be, I think someone check zirconium's thermal conductivity. They would be hard as hell to manufacture.

 

[theJesus]

yeah, that's why I would expect to pay an assload and have to have it custom-made. mmm, just the thought of diamond heatpipes and cooling fins

 

[exodusprime1337]

here's an interesting link into which metals conduct heat better. remember when comparing thermal conductivity and what dissapates and collects heat faster it's the same both ways, the difference is the temperatures outside of the metal that matter. people are too often mislead that one item conducts heat faster then the other because the larger the distance between the air and the metal temps the more the cooling capacity.

copper is a better conductor of heat then aluminum. having alu. fins doesn't make the cooler work better, the all copper cooler should conduct and diss. heat faster.

second the review on the sythe cooler or whatnot was totally blown out of proportion. if you read the last page, the replaced the cooler with the spring/screws from the thermalright unit and from what i appears beat out the alu. version.

imho the best would be a mercury based cooler. because merc is a metal and at the top of the list or close to it it'd be interesting to see how it could be implemented to cool a chip. (without killing/making you go crazy of course)
