The result if melting dowm zalman copper heatsinks. Not counting the stated aluminum parts such as fins.

Looks more like aluminum bronze.

Oh well, good thing I preferred Ice Hammer coolers.

I never dealt with their heat sinks, but I see one online that may be fake copper or a copper alloy.
A lot of cooper heat sinks will be a copper aluminum or copper nickel alloy it prevent the copper from dulling or corroding. Some say adding aluminum to the alloy makes it a better heat sink, but I never tested that.

Give me some time and I'll make a good wright up on spotting fake copper heat sinks.

Copper sinks heat better, but holds on to it longer as well.

Aluminum dissipates heat a lot faster than copper.

IMO the best compromise is having a thin copper base/heatspreader or heatpipes with aluminum fins.

The thinner and higher the quantity of fins the better as long as adequate air can still move between the fins to cool them down.

So they say. A lot of factors go into what makes a heatsink good.

Anyway Vantec copper iceberg ram heat sinks are not copper ether. But a copper aluminum alloy. Melting a few of them down the other day too. How one crushes ram heat sinks I don't know. 😕

Interesting and strange at the same time, because Zalman would have been sued for it since it clearly states " Pure copper" on those Zalman retail cooler boxes. Try older models. Zalman is still my weapon of choice.

You are too naive...

Pure copper plating*, infact water blcks aside i hardly ever see a 100% pure copper heatsink, they allmost always tend to be an alloy of some sort and that's for the best. Once I finsh my c2q bould ill have a pc i can post feom and will make a full report.

Anyway im out of old junk zalman coolers.
That being said I have owned some older zalman sinks and they definitely are pure copper.

Their heat pipped coolers always felt light for their size but this doesn't surprise me, even Apple does this. cnps 7000 series (the old school ones) were certainly copper and they are heavy, had some go through a house fire (lost a home to arson) and they didn't melt.

Not like you actually pick cooling systems in their price category just based on the composition. Those times I've been persuaded, it's because they performed well against the competition.

For air cooling thats definitely ture.

Water cooling is a little different.
