Is my AiO block getting eaten by corrosion? (feddit.org)

Today I was testing the RAM of a friend in my PC and since I had it opened up anyway, I thought I could renew my thermal paste as well. When removing the block from the CPU, I saw this:

Small hole with green and white corrosion
Big blob of white corrosion

To me, this looks like corrosion. The AiO is roughly 6 years old, so it's nearing its end of life anyway, but is that normal? Should I still use this?

Thanks for any advice.

Wait, there are nonconductive PC cooling fluids? I need to learn more.

There were some really toxic ones used in early supercomputer days.

Mineral oil is nonconductive. Some people even do aquarium builds with the whole mobo and gpu immersed in mineral oil. I don't think mineral oil is used in loop coolers though.

I don't know of any, but I don't keep up with the world of liquid cooling. Water is usually the most common, since it is cheap and has reliable performance.
