Thermalright Unveils True Copper Ultra-120 Extreme Coolers

[tiro_uspsss]

Remember, since copper's thermal conductivity is much MUCH higher than aluminum's, you need really good fans + air flow in your case to cool this baby down and get rid of all the heat it stores.

epic fail... seriously...

Buddy, copper has the 3rd highest thermal conductivity on Earth, behind diamond and silver. That means that whatever heat was transferred to the aluminum was dependent on the aluminum's ability to conduct heat energy. Now, since copper's conductivity is HIGHER, much MUCH higher (401 vs 237 W/(m·K)). That means that at any given time, it will be transferring and thus storing more heat energy than the aluminum version. Soooo that means that in order for the heatsink to not become overpowered by its own thermal conductivity, it needs to GET RID of the heat it conducts at a faster pace as well. Hence, the reason for more powerful fans.

whats it with the word 'store' - theres thermal conductance & thermal resistance

u make it sound as if a Alu HS doesnt need as powerful fans

That is purely theoretical.

what a crock of poo - I guess its only known as the Laws of Physics in a lab too then?

You forget that the heat transfer that occurs between the CPU and the copper heatsink is greater than that of the heatsink and the air. Although copper's heat capacity is a lot bigger than aluminum's, eventually, if the fans aren't getting rid of the heat at a greater rate than the heatsink is absorbing it, then the copper will start getting hotter and hotter and become useless.

lol. so do tell what would happen to the Alu HS?

That's why just looking at thermal conductivity doesn't tell the whole story. In a lab, yeah it does, but in real life it does not.

I sense... fail

An aluminum heatsink doesn't conduct as much, so its fans can remove the heat from the case without becoming overburdened.

repeat that ^ to urself a few times, till u realise what u have said....

You CANNOT expect a heatsink to cool well if you aren't removing that excess heat from the case. That's all I'm saying.

I fixed that sentence for u

First off, yeah a copper heatsink will be removing more heat but at the cost of ambient temperature rising IF YOU DON'T HAVE GOOD AIR FLOW.

u say that like its a bad thing... we want/need the air surrounding/passing the HS to rise in temp - it lets us know we are being successful in transferring heat from HS to air

don't have close to the perfect air flow you seem to think exists. Again, consumer PC's are not a lab. We don't live in a vacuum, figuratively speaking. I think you're applying absolute scientific laws in a chaotic environment without thinking outside the box and realizing that there are a few important factors that kill this naive thinking.

pfft. let me repeat it for u: Laws of Physics (in this case, thermal dynamics)
I'm afraid they apply all the time, everywhere, everyday
they are not askew just cause they have been proven in a lab.. air flow is air flow, 'perfect' or not - it will have the same affect, relative to its amount, so the Laws still apply, the formulas are still true, fair'n'square - the only thing that has changed are the numbers that are plugged in to their corresponding symbols, thus changing the answer, thats all..

...it's traumatizing.

the only thing traumatizing is the lack of knowledge displayed by a few pplz, esp. RE: Cu vs Al & thermal properties etc..



*unbelievable*
