when I use both cards for the calculation, the primary graphics card (UI) reaches a very high temperature and after a few minutes, 95 ° C temperature, the render stops. The second graphics card instead has a temperature of about 10 ° C lower.
If I reverse the cards and the problem is the same with the new primary video card.
If you use only one of the two cards the temperature is correct, about 80/84 ° c.
if I work with two different files, and I dedicate a graphics card to each, during render the temperatures are acceptable (about 80/84 ° c)
