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:
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.
I’d guess it’s a tiny leak and something in the heat transfer fluid can corrode copper when exposed to air. Copper turns blue when corroded, and the white buildup is probably the dissolved solutes from the fluid being left behind as the water evaporates.
Probably best to replace the AiO.
