Ill just say that cooper cools better, in any aspect/condition. Unfortunately, the misconception is not dead yet...
There are a variety of materials in a case, and heat can be trapped which is why there is such a thing as hot spots. To think that because copper is a better thermal conductor automatically makes better cooling is foolish. It isn't that simple...
it is that simple. Copper is better at cooling a surface than Aluminum. That is what you were arguing against. Now you're modifying your argument to say that because copper allows for lower thermal resistance of heat transfer from the CPU it's heating the ambient air faster(true), and causing hot spots and this makes copper not as acceptable. Well, it's cooling the CPU better, and I really don't think it's going to be of the magnitude that we'll see even a 2-3C increase in case temps, unless of course you're trying to use this in an extremely quiet system, which I'm assuming no one will do.
You are totally off...show me one post where I said Aluminum is better than copper at transferring heat. What I've been saying all along is that with greater heat transfer comes the risk of greater ambient temps IF you don't have good fans (which HAS been my point all along...the need for powerful fans to offset copper's much great heat transferring ability).

Lets remember to keep this friendly and also remember my last point from my post:
We will find out the truth ONLY when one of us has tested this here at XS.
Until then all is speculation..
But it really is pretty!
Crunch with us, the XS WCG team
The XS WCG team needs your support.
A good project with good goals.
Come join us,get that warm fuzzy feeling that you've done something good for mankind.
I'm doing my best to be polite, I like constructive arguments. If I'm coming off as overly negative towards anyone, I apologize.Gentleman:

Man, anyone who reads my posts from my 1st to my last in this thread will realize what I've been saying. You don't need to try and make me look like a back peddler just cause a couple of ppl said they get what I'm trying to say and that I may have a point. Sheesh.
Agreed. Teh massive and/or shiny is always gonna sell me.Gentleman:

Earlier you said-
You didn't mention anything about case fans, just a fan for the heatsink itself. Here's what I don't get, you're saying we should have higher speed case fans if we use Cu heatsinks, well, what happens if we use Al heatsinks? Should we need less airflow?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.
In reality, if you use Al, your CPU is warmer, so, you'd use a higher speed fan to force convection from the heatsink faster. You don't need to offset anything. How much of an increase in case temps do you think a copper version is going to give you?
I don't mean to put you on the spot, but looking through it seems like you've expanded and changed your initial stance on the subject.

which is total bs
a 50W chip doesn't pump more heat into the case because you put a better cooler on it
the point you are implying about more heat being transferred to the PCB when you have a poorer heatsink doesn't change that
since the rate of heat transfer between air and a surface is dependant only on the rate of air-flow and temperature difference between the surface and the air i think if you were to say "the copper and aluminium heatsink versions would be the same temperature in the same conditions (same air flow, air temperature, and cpu load), but the temperature difference between the heatsink and CPU would be lower with the copper heatsink" you'd be 90% correct (there'd be slight differences, eg with the copper heatsink the base would be cooler due to the cooler CPU underneath, while the heat on the fins would be less concentrated around the heatpipes)

Probably through the PCB, surrounded materials the chip is in contact with, etc, etc, etc.Indeed...the "unknown" mysterious location might be inside the case....since the CPU is placed inside the case

If the Al won't wick away the heat fast enough from the CPU, it'll disperse with whatever else it is in contact with.
That makes total sense. Baron's point does make sense, though it's a bit .. confusing in presentation.
E7200 @ 3.4 ; 7870 GHz 2 GB
Intel's atom is a terrible chip.
If your CPU puts out 50 watts of heat, and say with a copper cooler it runs at 35*C, and with an aluminum it runs at 45*C, and those are steady temperatures, they don't increase at all after that point. 50 watts is 50 watts, whether it is at 35*C or 45*C. You put the copper cooler on the CPU, it simple is able to take the heat away from the CPU faster, but the same 50 watts of heat is still being dumped into the case from the aluminum heatsink.
There is no such thing as a free lunch. If 50 watts is being dissipated by the alu sink, 50 watts is going to be dissipated by the copper sink. With the copper sink you will get more cooler air, while with the alu sink you get less hotter air. It all works out the same in the end.
Fold for XS!
You know you want to
No, what happens with Al as opposed to Cu is that the rate of heat transfer is lower, so instead the CPU is hotter as a result. Sure, you'll have some heat transfer to the socket, and to other places, but the surface area for heat transfer in those directions are much much smaller, so their resistance to heat transfer is much much greater that they don't really do much in the grand scheme.
Yes, I got the point, I was just kiddin. He obviously knows that the "location" is inside the case lol. I understand that the real point is, "where" in the case.
Its an matter of heat distribution inside the case, since the heat source output the same watts regardless of the heatsink material.
With cooper, you get colder hot spots, therefore you get hotter surrounding air. This is ideal, it makes easier getting the heat out of the case by using fans.
With alu the inverse is true. More heat build up in the different materials, like the cpu itself, socket area etc, rather than surrounding air, so its harder to get the heat out of the case.
Yes, an better thermal conductor automatically makes better cooling. Its that simple. Colder hot spots, in detriment of surrounding air, is obviously better than the opposite.
My english is not the best, so dont take it too literally
