i have 3 old cards rx470 4g msi which run hotter than my other cards at 75-76 c , is it safe or not as i run them on low TDP with this temps
If you have MSI Armor, then that's okay, because they have a very poor cooling system.I have several video cards operating at temperatures above 80 degrees, and in the summer the temperature was about 90 degrees.
Yes I have some invalid shares, but it doesn't bother me.
Install additional cooling, this will reduce a few degrees on each video card.

I bought these video cards from another miner a couple of years ago. Bios firmware leads to problems and freezes; during overclocking, the mining farm works stably for 1-2 hours.
If the temperature is more than 90 degrees, then the miner will turn it off.
I did a lot of experiments with these cards, but every time I was convinced that these values are the best, because the farm is stable.
