    No fan detected on Asus N550JV on Saucy

    Hi,

    I've an Asus n550JV laptop with latest Haswell chipset. Everything is working fine, only issue is the fan. It's always turned off, and is not detected by lm-sensors. I did run sensors-detect and answered yes to all questions, just suggests to load core-temp module, no fan info.
    If I run CPU intensive tasks, the laptop becomes pretty hot, CPU temperature reaches 95 °C and then the kernel throttles the CPU frequency to limit the temperature. The fan is always off.

    Is there any way to have the fan being detected properly ?
