Mixing thermal compound

Before you post, please read and understand what i'm thinking. [\b]


I want to mix Liquid Ultra and Grizzly Conductonaut into a tub to give a "Super Paste" , one is conductive and the other is pure liquid metal.

Planning to delid i7 7700k and put this mix onto it if it works.

I will be cooling it with a water cooler, and its pretty good, the Cooler Master MasterLiquid Pro 280. And I'm planning to buy Grizzly Hydronaut to put it between the cooler and IHS, allowing for utmost cooling potential while at 5 GHz over clock, at the lowest voltage I can give it.

Good idea or scrap?

  1. And what do you expect this mixture to do, and how?
  2. ... Maybe reading the post is a good idea.

    Yes, I read the whole thing.
    I'm wondering what performance benefit you're expecting to see, vs one or the other on its own. And your rationale for why.

  4. Lower temps really.

    I expect Liquid Ultra and a conductive paste to dissipate heat as much as possible, along with water cooling and hydronaut paste.
  5. I'm assuming when you say "conductive" you're referring to electrical conductivity. Both are liquid metal pastes, so I would expect both to be electrically conductive. Even if only one of them was electrically conductive, I don't see why you'd expect a combination of the two would perform better than just using one or the other.
  6. I'm no expert on thermal paste, but it sounds like a pretty whacky idea to me. I would just research reviews on the best thermal paste for your purpose, and chose the best one.
  7. Will the two paste's become corrosive if I mix them and put it onto the die? That's the question I mainly want to solve.

    Or, would it be better to put grizzly Conductonaut between the cooler and IHS and leave Liquid Ultra to do the die's work?

    Corrosive?
    Completely unknown. The number of people who have actually done this is approx zero.

    Mix a small batch.
    Obtain a high power microscope.
    Clean all the surfaces.
    Inspect and document any micropitting.
    Spread it over the same materials that you have on the CPU.
    Heat to 85C. Leave it heated for a few weeks.
    Inspect again for micropits that may have resulted from corrosion.

    This is what is called 'testing'.
  9. The only way you would know whether mixing the 2 products will create any undesirable side effects (such as corrosion), would be to know the exact chemical composition of both products, and then a knowledge of chemistry, and how the chemicals will react over time, with high temperatures applied. Sounds like a project for a grad student studying chemistry.

    I would do what you said in your last post.
  10. Right, so I should use Grizzly Conductonaut for the cooler and IHS rather than hydronaut right?

    Thermal paste does not 'dissipate' heat, it transfers it to the HSF which dissipates it.
