I own 5173 1070 black edition, which has no back plate. No worries if you have the same. I put temp sensor on back of card where the heat issues have been shown. Temps never got over 65c in that area while running card at 100% load playing Overwatch. I am using a Coolermaster haf 932 case which has good ventilation. I have owned evga products for years, and continue to stick by their products. Too many people making a mountain out of a mole hill. Give it a rest people!!!
Note: Running power limit at 112%, Temp limit 92c, core clock +115, memory clock +300. using afterburner. Fan curve, no fan until 37c, ramping up to 100% at 90C.
This has been the most silent video card i have ever owned, and actually now have in 2 pcs in my home now.
