[SOLVED] does cooling graphic card backplate lower gpu temperature

[andess]

So I have a rx 470, the backplane is very hot, like 80+°C, so I put 2 fans to cool down my graphics card. Does it really help??

When it's plastic and has no actual contact with graphics card parts, it does not serve as cooling. If it's metal and touching some parts, it can help spread heat.
Maybe a GPU repaste is in order!
