I Have An Amd Athlon Xp Processor And Amd Xp Heat
I have an AMD Athlon XP processor and AMD XP heat sink. It seems to do the job, but it's probably the fan that does most of the work.
The sink is aluminium. Aluminium is a good metal for destroying heat, but not so much for carrying it, so most of the heat doesn't leave the CPU area. Copper is good for transporting heat, and so, with a copper heatsink, heat would travel away from the CPU to the furthest point. However, copper isn't really any good at destroying the heat. With aluminium, then, with the heat being contained next to the CPU, the CPU is held warm by the heatsink itself! That doesn't help!
Today, cleverly enough, you can buy heatsinks that are made of copper, but are coated in aluminium, or even better, are copper up to almost the top of the sink, but at the very top are aluminium.
Overall, however, the heatsink is keeping my CPU at quite a satisfactory temperature - my CPU is happy! :-)
Hello kiyawhite, I'm unsure of your use of the terms 'destroying' and 'transporting' heat in relation to a heat sink. 'Conduction' is the term normally used, or at least it was when I was in electronics.
Heat sinks for cooling electronic items are normally made from aluminium which is almost as good a conductor of heat as copper and is much lighter, cheaper and more easily fabricated. They are usually matt blackened to allow more efficient absorption and radiation of heat.
Of course, a fan blowing across the heat sink considerably speeds up the radiation process.
For the ultimate in CPU cooling you'll have to consider oil, but that is another story!
