Hello ! Tell me please the optimal range of air temperature for the graphics card. If it works at zero degrees, turns off the electricity, then the card is started, is it harmful or not ? If when you turn on the electricity at zero degrees, the air conditioner immediately heats the air, and the video card is cold, can condensate form ? The model is SAPPHIRE AMD Radeon RX 570 , 11266-09-20G NITRO+ RX 570 8G OC, 8Гб, GDDR5. It works in the garage and if the power goes out, the ambient temperature drops to zero degrees.
