Title:
temperature overheating of cpu and radeon in 12.10 and above
Status in “xserver-xorg-video-ati” package in Ubuntu:
Confirmed
Bug description:
13.04 Ubuntustudio 64 bit
under moderate load temperature is around 81c
under high load (playing video inside a virtualbox) temperature hit
94c.... at which point I turned it off
I have tested this with all 3 of the radeon drivers, with no
significant difference.
The radeon temp is always about 2-3 degrees hotter than the rest, so
suspect that is souce of problem.
10.10 does not have this problem at all
12.04 runs 5-10 degrees hotter on average than does 10.10
but starting with 12.10 the temperature gets unusably hot
