A lot of the premium thermal paste products are non-conductive (electrically) and still way better than the stuff they put on at the factory and will improve you situation.

I don’t think that thermal grizzly products are a bad place to start looking. I haven’t tried them myself, but GamersNexus are advertising/recommending them and I do trust them.

> I haven’t tried them myself,

you should. kryonaut and conductonaut are both great. However I'd not recommend liquid metal (gallium) for daily use in a laptop with low tension force. I use liquid metal on delidded ones and kryounat elsewhere.

Is there no chance of that gallium alloy amalgamating with other metals it might encounter? It seems really sketchy, but I guess it's probably not since I've not heard horror stories.

Gallium eats aluminum like butter[0]:. Copper is safe, nickel plated copper is ok as well (might tarnish though)... solder joins are dead however.

One should be very careful if that stuff can leak.
