all hs need high cfm to moderate the air temperature to be similar to the hs (faster heat exchange) but generally copper needs a high pressure fan to run even more efficient compared to alu. such fan can be found on most high speed rpm. why is pressure so crucial? most of the fans out there can easily achieve a high cfm, but to get that much of air being squeeze in between the fins, you need the fast fan to squeeze the air through it.
coppers are great and a small copper hs perform as efficient as those bulky alu fans. for me its a no no for copper. mainly coppers are fan dependent, if you're ocing your pc at high clock speed. consider the heat generated is high. In the event of fan breakdown. the hs will have a sudden increment in heat. as mention. copper has lower specific heat. so they generally stores less heat thus heat rises. if you're lucky, the overheat protection from the mobo will shutdown just in time before the processor gets fried.
alu's my choice la. since it can perform fanless e.g si-120 and xp120. i think its the plus side. ofcourse it can't achieve a higher overclockable ability for the processor. but i'm willing to play on the safe side. In addition, alu hs are easy to clean and they don't oxidize like copper. cleaning is also a breeze since you just need to clean with water and soap. copper? clean the dust then celup inside coke to clear the oxidized parts. they can't be exposed to water. on the long run when you're tired with the noise of the cpu( getting deaf), you'll start to go for quiet hs.
i too will choose x-dream. copper and alu makes a good pair. one sucks the heat out faster while the other dissipates heat out. perfect duo just like ninja.
So, the thing you're saying here is that the X dream III is good? coppers are great and a small copper hs perform as efficient as those bulky alu fans. for me its a no no for copper. mainly coppers are fan dependent, if you're ocing your pc at high clock speed. consider the heat generated is high.

So it means that Aluminium + Copper is good for dissipating heat?
Just wanna ask, what about my Hyper 6+?
It's base is copper, the heatpipe is copper and the fins is aluminium, is it good too?
Need some answers here...
