What is the Octane GTX 1080 N17E-G3 GPU die made of (material-wise)

[David010203]

Hi guys,

Just a quick question as I am researching thermal compounds and I've come across Thermal Grizzly Conductonaut Liquid Metal. It is strongly advised that you shouldn't use it if you would have any aluminium making contact with it. I have an Octane III, as far as I know the heatsink is made of copper, however, I am unsure about what material the actual GPU die is made of. Do you guys have any knowledge on this subject?

Thanks

I can't say what the IHS is made of (because I don't know ... not like its a conspiracy or anything) - but the Thermal Grizzly Conductonaut Liquid Metal is sold as CPU thermal paste so its 'probably' ok... You could ask the seller what they think maybe if no one can answer the question here?

A quick google suggests the IHS plates on CPU chips is a nickel/copper plate https://www.ekwb.com/blog/thermal-compound-guide/ it is probably the same for GPU chips but I'm by no means sure.

Looking online, people have indeed repasted their GPU with Conductonaut, some guy even made a video guide

The CPU in the Octane, 6700K in my case, is covered by an IHS and apparently there is not much point in applying Conductonaut onto the IHS. The big temperature difference happens when you actually delid the CPU and repaste the actual die with Conductonaut, followed by "reglueing" the IHS onto it. Delidding is too crazy for me though.

In the GPU's case however, I think it would be worth it, since it's a naked die. Hence my whole concern of what material the die is made of, to make sure that in the long run the Conductonaut LM will not corrode it, etc.
