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℃).
