>What is the basis for pretending otherwise?
That's it? Thanks for the clarification. You have no knowledge of this heatsink whatever? Is that right?
>Thermalright 'sinks are not that thin. "Kinda" similar thickness is not the same thickness.
So then what is the gauge of the Thermalright XP90 vs this one? Any idea, roughly? Is it about half? 80% 90% 99% Any idea what the optimum gauge might be? How is it determined what the ideal gauge shold be?
>Who said they should be copper? Not I, but they should in fact EITHER be copper, OR thicker.
How about neither, which was the point?
>No the fins aren't bonded well, how can it not be obvious? You are making arbitrary nonsense comparisons with things like household electrical wiring.
Since you have no knowledge of this heatsink whatever, how could it it be obvious to you? I don't get it.
It is not reasoning by analogy. My point was that pressure does make excellent contact and in fact experts prefer that technology over alternatives. I don't see how you missed it.
>Anodizing vs plating is NOT the same, completely different process, different reason, and different result. It's mainly there to make the 'sink look like it's not bare aluminum even though bare aluminum conducts better than that does.
>Plating does in fact help conduct to whatever degree the plating itself is a better conductor. Granted that may be a small % difference, too trivial to even consider in many cases but nevertheless, does have the potential to change conduction or radiation.
I'm not sure what the argument is on this one. As I said, the difference is which electrode the ions go to. Look it up. Functionally, coating metal is almost exclusively to reduce corrosion, which in turn improves appearance. So the function of anodizing and plating is the same. Of course it doesn't make the least bit of difference for heat because the anodized coating is so microscopic as to be translucent (which is how they get those peculiar metallic colors.) All metal oxidizes immediately after exposure to the air and so has a coating on it. Metals used for plating just stay looking nice because the oxide which forms is thin, even, translucent, and very impervious to passing oxygen. Nowadays any finish aluminum, even silver colored, is anodized to protect it, because exposed aluminum gets looking nasty fast. You can't have bare aluminum that is exposed to the air. It is either coated destructively with aluminum oxide by being in the air, or protectively by being anodized. In other words, an anodized aluminum surface has less coating on it than a "natural" one. And plated sufaces also have a coating, due to oxidation, which is what protects it, and which may well be thicker than an anodized one. The reason they don't plate aluminum, I believe, is that it does not easily accept plating, and it is just the opposite for many other metals, so they plate those. That's it.
>I am apathetic whether you agree, but the sad part is you pretend to know all towards a delusion about a 'sink that is mediocre at best.
Is it supposed to matter that you are apathetic? You did not substantiate anything. I just find technology interesting and like examining it. All I did was point out what was unsubstantiated. That tends to make people mad, I know, but I tried to tone it down.
You didn't mention what my supposed delusion was. I think I'm being realistic and accurate about the technology. I'm not making any claim whatsosever about this particular heat sink. This could be rotten a heatsink, but if it is, there is nothing at all in what you said that demonstrates it.
One site tested this heat sink and found it among the best (in 2004.) Another tester found that it almost didn't work, and "exposed" it (as a fraud), but discredited himself as a doofus, at least in my eyes, with the heatpipe foolishness. It is easier to believe the doofus botched something than to believe two tests could be legitimately so contrary.
