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.
Which part of the world are you from? In summer none of my AMD or Nvidia GPUs goes over 60°C seeing yours at 90°C is surprising, I wouldn't be able to sleep at night if my GPUs temp are over 70°C this is not a safe temp for 24hrs operation
