349.12 drivers bug: no fan information/no fan control in nvidia-settings

Here’s how it looks like:

OS: CentOS 6.6
Kernel: 3.19 x86 vanilla
GPU: GeForce GTX 660

Also, “Enable GPU Fan Settings” checkbox does nothing.

Why a new thread?
There is allready one: Can't control fan speed with beta driver 349.12 - Linux - NVIDIA Developer Forums

Didn’t notice, sorry.
