Copper vs. Nickel thermal conductivity?

What is better copper or nickel? (Waterblocks/Heatsinks) :bounce:

More about copper nickel thermal conductivity
  1. Waterblocks and heatsinks are typically only nickel-plated, so your comparison isn't a 1:1.

    Nickel plating is only for looks and corrosion prevention.
  2. Best answer

    Well they all perform the same, the only difference is looks, and the nickel prevents the copper from oxidising. Again, this will not affect the performance of the block.

  3. Thermal conductivity values. Unless you can get a artificial diamond or silver water block, copper is the best choice and that's what most if not all heatsinks, air and water, use.
  4. Thermal conductivity of Nickel is 90.9 W/(m·K).

    Thermal conductivity of Copper is 401 W/(m·K).

    The electroplated nickel on the copper block is so thin that it can virtually be ignored when considering thermal conductivity.

    It would be stupid to make a block out of solid nickel. Its thermal performance would be terrible.

    Silver is only 7% better than copper but is much more expensive. Pure silver also oxidizes quicker than copper. About 10 years ago, when silver was much cheaper, there was a heatsink, the Noise Control Silverado, that used a 50 gram slug of pure silver.
  5. Yes.

    Again...like I mentioned, the nickel on blocks is only for aesthetics; it serves no real cooling purpose. But, great additional supporting info.

    Which as of this moment is $58.31 for just the silver.
  7. ^LOL @ your little blurb on magic smoke.

    Classic.
  8. Hey, graphene in wiki? I take it that's some sort of form of Carbon? Is it possible to develop a paste for that since it's the highest in that wiki table?
  9. ^Yes, it's pretty much an atomically altered derivative of graphite. However, given the fact that it's typically produced in a lab at the atomic level via sophisticated and controlled methods, I'm guessing that alone would put it financially beyond mainstream PC applications.

    Graphene Wiki

    A pretty interesting read; and considering it was the basis of a Scientific Nobel Prize in the last few years, I think development into other areas of application will be explored before it makes it into a tube of TIM.

    In 2008 graphene produced by exfoliation was one of the most expensive materials on Earth, with a sample that can be placed at the cross section of a human hair costing more than $1,000 as of April 2008 (about $100,000,000/cm^2)
  10. They are working on methods of mass production that hopefully will allow for applications to begin to become practical in the near future. IIRC, in that same article it is mentioned that the price of a graphene coated silicon carbide wafer was $100 per cm^2, still a little pricey, but for a high end chip not horrible.
  11. It will have to find its way into a practical application as a thermal transfer material, first. However, it's likely it would be used for actual computing applications instead.
  12. I'm having the Hope Diamond reshaped and hollowed out a bit so I can use it for my cpu water block.
  13. lol thats about where i though this was going

    lol. I couldn't think of a better use for it myself.

    I live for those times when I get to say, "Welp, you let the magic smoke out. It's pretty much dead."
