Been trying out some new vid cards. At first, I installed a Sapphire NITRO+ Radeon RX 480 4GB and it ran great. Great on the burn in,  and great with memory consuming games like DOOM, but when I would go into FOB on MGSV the fan would spike to 100% and go into an infinite loop error. I would shut the game and bring up Trixx to try adjusting the fan, but it was unresponsive and would blue screen. I figured it might just be a minor fix, but I looked and saw that lots of people were having the same problem. IT was possible a format could have fixed it, but I decided to unload it before I was stuck with it. It was a great card, but it was either defective, or it was flaky as hell. Now I have the MSI GTX 1060 GAMING X 6G installed. I went with a different chipset to avoid the potential that all the 480's would give me the same result. The 1060 is a great card in many ways, but the fans! I can't hear them no matter what... they are like, totally silent! All games are running good and there doesn't seem to be any issues, but when I ran the burn in, I noticed that some parts of the cabinet were getting warm towards the back of the rig near the card. This is of course when I was demanding 99% of the GPU with furmark for 10 minutes. Is that something that could become an issue? should I set up another fan, or worry about it? I doubt many games will call for that much power, but if it did, is such warmth on the back of the cabinet generally something to worry about?
