With mesa 17.3 (and maybe kernel >= 4.13), using GL,VAAPI or VDPAU, GPU temperature makes to be too hot. Almost upper than 60℃ with RADEON HD7770 (less than 15℃ at room). When not using GL etc, temperature upper than 50℃. With earlier version of GL, VAAPI and VDPAU, temperature is less than 60℃ (at worst, less than 70℃). Regards, Ohta.
are you using amdgpu.ko kernel driver? if so... https://forum-en.msi.com/index.php?topic=298468.0 Do you see the same powerplay error messages in the kernel log as described on that thread. There is a workaround to use fancontrol script from lm_sensors Also try reading your bios file from your card, if you can't it will print an error about PCIE MMIO BAR regions. I have a theory this relates to a buggy motherboard bios efi code - as do others.
Sorry for later. I don't use AMDGPU, (still) using RADEON kernel driver. But, this seems to same issue. I install fancontrol and set parameters of /etc/fancontrol , this issue seems to be fixed. Thanks for your advice. Regards, Ohta. # I'm using SAPPHIRE's RADEON HD7770 GPU board, and ASROCK 990FX Extreme4 mainboard.
