Comment 0 for bug 1322983

I have an Asus S7F laptop and most of the times, the fan is not spinning at all. When booting in Windows 7, the fan works.
Temperature reaches sometimes over 80 degrees, so I had to put an additional fan next to my laptop just to keep it at 70 degrees. Any idea what could it be the cause? Unsupported sensor maybe?
