I have a XFX vega 56 that is relatively new(only got it 2 months ago). Most of the gaming I do is not at 4k or graphic heavy 3d games, but I do occasionally do play some vr games. Since Ive gotten the GPU though Ive noticed after playing VR the temp of the unit becomes really high and will not go down. Ive checked a bunch of different temp monitor software just to make sure it wasnt one specific software with a bug. To give an example of what I mean by high temp, prior to touching a VR game it will sit at 30-40C idle. As soon as I open a VR game its will jump up to 70C. While Im not to concerned about it getting hot under load, my concern is that even after the VR game is closed its still at 70C. Ive left it for 12+ hours idle to see if that would cause it to cool down, but even then still at over 70C. The only way Ive been able to get it back down to normal idle range(30-40C) is to reboot my computer.
