https://bugzilla.kernel.org/show_bug.cgi?id=71711 --- Comment #7 from Roman Spirgi <the.ant@xxxxxxx> --- I'm not sure if this is related to this bug but since Kernel 3.13 my fan speed is far to high and noisy as soon as the system is booting up ... I'm using Fedora 20. With Kernel 3.12.X everything was fine instead and fan speed was on a acceptable level ...

Looks like Nouveau fan control does not work. No idea what may be causing this ... well, possibly. There are two suspicious commits between 3.12 and 3.13. Maybe the "remove everything" commit has undesirable side effects. eec9901 drm/nouveau/hwmon: fix compilation without CONFIG_HWMON b9ed919 drm/nouveau/drm/pm: remove everything except the hwmon interfaces to THERM I would suggest to open a separate bug against the Nouveau component. [ Side note: The displayed values for hyst are wrong. Those should be absolute temperatures, not temperature differences. But that is yet another bug. ]

Something in your system configuration is wrong. Usually this comes from the BIOS, so you you might want to check if there is a BIOS upgrade available. It looks like the system believes that your CPU is freezing and therefore runs the CPU fan at minimum speed. That may be ok with the current load, but might be a problem if the CPUs get busy and run hot. That is not related to the nouveau problem, though.
