chuck4456 Posted September 21, 2008 Posted September 21, 2008 So is it definitely going to be available? I have a silver TRUE, a black TRUE, and an HR01 Plus. Copper would complete the collection! Share this post Link to post Share on other sites More sharing options...
Andrewr05 Posted September 21, 2008 Posted September 21, 2008 Their previous copper versions of their existing but discontinued heatsinks did better than their aluminum counterparts... Share this post Link to post Share on other sites More sharing options...
Kash Posted September 21, 2008 Posted September 21, 2008 Copper can dissipate heat nearly twice as fast, although it is much more expensive (and heavy) So yeah, paired with a good fan it should take the temp down lower than the aluminium true Actually, no. Copper doesn't dissipate heat twice as fast, it absorbs heat twice as fast. Aluminum dissipates far more readily. Hence why companies make aluminum/copper hybrids with copper bases and aluminum fins.

Zertz Posted September 21, 2008 Posted September 21, 2008 Ok, I got sources to back me up this time http://en.wikipedia.org/wiki/Thermal_conductance Companies use aluminium because it is 3 times cheaper!

Compxpert Posted September 21, 2008 Posted September 21, 2008 At a price of almost $100 I think I'll stick with my True "Black". Share this post Link to post Share on other sites More sharing options...

Hence why companies make aluminum/copper hybrids with copper bases and aluminum fins. I'm sorry, but your statement doesn't make any physical sense. Heat transfer does not care which which way heat is flowing. It is driven by the temperature difference. Price. Zertz hit the nail on the head. The thermal conductivity of copper is superior...but more expensive... If every company made solid copper heatsinks, they'd all be very expensive. Fins consume a large amount of matter...it is cheaper to add more fins and use Aluminum. It is more effective to have copper bases than aluminum. If money wasn't an issue...we'd see more silver heatsinks. I've seen silver water blocks somewhere, but the price was atrocious.

davidst Posted September 21, 2008 Posted September 21, 2008 Yea it is very nice, copper, one reason I have a Zalman . Share this post Link to post Share on other sites More sharing options...
Zertz Posted September 21, 2008 Posted September 21, 2008 If money wasn't an issue...we'd see more silver heatsinks. I've seen silver water blocks somewhere, but the price was atrocious. Diamond heatsinks would be even better, just a tad more expensive Share this post Link to post Share on other sites More sharing options...

It is driven by the temperature difference.Errr... Copper will conduct heat better than aluminum, aluminum will dissipate heat better than copper... I'll try to word it how I see it... Copper conducts heat better with physical contact (i.e. from CPU-TIM-HS) but will "hold" heat and not dissipate it (i.e. from heatsink to air) as quick as aluminum. You see there is advantages and disadvantages to both copper and aluminum, which is why we have copper aluminum hybrids (i.e. an aluminum heatsink with a copper base). The copper will absorb more heat than the same amount of aluminum and the aluminum will dissipate more heat than the same amount of copper...

COPPER will dissipate heat better. Direction does not matter. There is no "storage", for most computer applications, everything is steady state.
