I recently upgraded to a brand new Powercolor Rx 480 8Gb Graphics card and have been using it for about two weeks and was slightly concerned by the average of 70C in games like DOOM and Watch Dogs but brushed it off. I decided to play GTA 5 and it ran at around 100fps on "Very High" everything. Unfortunately, there seems to be a problem with MSI afterburner and GTA 5 launch errors that prevent the game from launching so I could not monitor temps or change fan speed and left it on "auto" but after a day of it running fine I was in the middle of an Online session when the entire power to my PC was cut then followed by an auto startup. I found this suspicious but in my head brushed it off as a mini power cut as my room lights were turned off at the time. But it then happened a few more times and I realized it was most likely overheating. It happened again and I opened my case and touched my finger against the exposed heatsink and it was clearly too hot. I put all my textures and settings down to medium and low and it still happened. At the moment i just have a desk fan wedged up in my case. I also tried to find a GPU fan speed controller in my BIOS but can't see one Can anyone suggest a fix?
P.S I found that I and a lot of other people online have a problem where MSI Afterburner causes GTA 5 to crash on start so you have to kill the MSI background process in task manager.
