Does anyone have an experience with 1 fan variants of cards for mining? (XFX, PowerColor). Do they run a lot hotter than others because of the 1 fan, or is it okay? Also the MSI Armor RX470's, how's their cooling? I've heard that they run hot because they only have 2 heat pipes, but I don't have one to confirm. I have an RX480 Armor with 3 heat pipes and it runs fine.
I have 8 Power Color Red Devil Single Fan cards and they are actually my coolest running cards before and after undervolting.
