Thermal Grizzly Conductonaut

F
Ranked #15 in Thermal Paste
0 LP on the category ladder what's LP?

A genuine ownership hazard outside expert direct-die builds. Honeywell PTM7950 delivers the same thermal class without the risk, which is why Conductonaut finishes last on a general board.

Flagged as a product to avoid

10 of 12 research runs entered this as a product to avoid rather than a pick.

Liquid metal carries long-term reliability concerns - leakage currents and heat can trigger electrical damage over time - and a spill or overhang is a board-killing event because it is electrically conductive. It also attacks aluminum coolers and needs periodic maintenance, making it a poor ownership bet outside expert direct-die builds.

  2. Electrically conductive and corrosive to aluminium, and the temperature gain over a good paste only shows up in direct-die laptop mods; with the good-to-great gap tiny per Xda-developers, the risk is pointless for desktop builds.

    Flagged 23 September 2026
  3. Electrically conductive and unforgiving liquid metal that only makes sense on delidded dies or dedicated enthusiast builds, and punishes any application mistake on a normal CPU or GPU. For the effect most buyers actually want, Honeywell PTM7950 or ARCTIC MX-6 is the right purchase.

  4. It is electrically conductive, corrosive to aluminium, unforgiving of application mistakes, and a single slip can kill a motherboard - the failure class Sheen Thermal documents. For everyone but delidding specialists, PTM7950 or the Kryosheet delivers most of the benefit with none of the hazard.

  5. Liquid metal is a legitimate extreme-overclocking tool, but it is electrically conductive, corrodes aluminum, really only makes sense on a direct-die mount, and the real-world gain over Duronaut or PTM7950 is a degree or two. For the money and the risk to your hardware, mainstream buyers should avoid it.

  6. Electrically conductive liquid metal can cause leakage currents and is unsuitable for aluminum, with performance degrading over time.

    Flagged 23 September 2026
  7. Electrically conductive and risky for normal builds; only necessary for extreme delidding scenarios, making it unsuitable for typical users.

  8. It is electrically conductive and can corrode aluminum, requiring extreme care; its hazard profile makes it unsuitable for mainstream builds.

    Flagged 23 September 2026
  9. Electrically conductive liquid metal that is unsafe for standard builds and only justified for delidded CPUs, offering only a fraction of a degree gain for a tube that costs many times more.

    Flagged 23 September 2026
  10. Liquid metal poses a risk of shorting; testing shows no real benefit over non-conductive pastes, making it unsuitable for typical users.
