So yesterday, my aluminium intel heatsink pins screwed up when I'm servicing the fan. Now I bought an Intel Copper Heatsink (LGA775) for my Core 2 Duo E7600 (3066 MHz) CPU. Now, I'm living in Malaysia with room temprature of 33 Celcius, and CPU temprature 36 Celcius on idle and 49 Celcius when loading when using the copper ones. Which better if you think, copper or aluminium ones?
i would think copper, you can have more and thinner fins to dissipate the heat then with aluminum
Copper transmits heat better than aluminum does, and so if you are talking about two heatsinks with the exact same physical design, but one made of copper and the other aluminum, copper is the better choice and will keep the processor cooler. However, there are cheap copper heatsinks which do not do as good a job at cooling as more expensive aluminum heatsinks with fans attached, so it's not a 100% guarantee that any one made with copper will outperform any aluminum model. 49 degrees Celsius is plenty cool for a Core 2 Duo, so I don't think you need to worry, but in general copper sinks outperform aluminum ones.
