    Heatsink cement?

    I had been using Arctic Silver 2 part heatsink cement. But 1 part set up in the tube and I can't seem to find it anymore. What do you guys recommend for this. Dell doesn't put heatsinks on their VRM and I find they help when overclocking these things.
    I've been told not to use Superglue because the vapors when heated can screw up the lasers in optical drives.

    Superglue also fails with heat. I use this stuff https://www.aliexpress.com/item/1005002615667957.html it dries hard but with a slight bit of flex.

      I've used JB weld for decades. Transfers heat nicely and the sink will never come off!

        JBW sounds interesting. But I harvest my expensive Enzotech copper heatsinks from my old projects. I think the JBW would win that arguement.

          I've used JB Quick for this, including copper heatsinks to MOSFET cases.

          If/when you need to save them, a quick blast from the torch expands the heatsink and breaks the bond.

          Do this in a somewhat "controlled" manner, obviously...
          Then scrape the residue from the heatsink, preferably when still warm.
          Obviously, anything you remove the heatsink from in this manner will be damaged.


          Now if there's a need for something more thermally conductive, use equal parts of JBQ resin & hardener, and half as much Arctic Alumina.
          So 1 part JBQ resin, 1 part JBQ hardener, and 1/2 part AA.
          It doesn't seem like it would work, but I've used it for GPU RAM sinks & NVME SSD cooling.
          "pokemon go... to hell!"

          EOL it...

            you can buy stuff designed for the job.
            the best - but expensive is zinc loaded epoxy.

            much cheaper is thermal rtv - you can get that on ali-express.
            it's usually gray.

              I started looking around at Digi Key lots of choices there. Newegg was a waste of time.
