Rafal,
Yup. In most cases fans are self-adjusting to heat. If you downclock GPU, it will produce less heat and so fan will slow down.
To downclock you need working radeon (DDX) or KMS. Both can downclock GPU by AtomBIOS commands, but I'm not sure how stable support for R5xxx is.
as the radeon driver seems to no support the card at all - where can I read more about this magical KMS thing? how would I issue these AtomBIOS commands?
Support for evergreen (R5xxx) is almost the same in KMS and radeon (xf86-video-ati). I think radeon has some problem when going back to console, that's all difference. In both cases you have to use software from git. In case of radeon it's standard master branch of git, in case of KMS drm-radeom-testing branch will be needed from airled's repository. In case of radeon there is "ForceLowPowerMode" option for xorg.conf In case of drm-radeon-testinth there is "dynpm" parameter. -- Rafał -- To unsubscribe, e-mail: radeonhd+unsubscribe@opensuse.org For additional commands, e-mail: radeonhd+help@opensuse.org
