Fortunately not. But due to new supported hardware, of which I don't know 
the actual temperature limits of processor, harddisk and other components, 
it just feels safer with this lower settings.

Another point is, that you need to have the "kernelmode=1" option when 
loading the module to enable fan control. When searching the internet for 
acerhdf tutorials, you see, everybody not only setting kernelmode=1 but 
also setting the fanon and fanoff variables. So I think it won't change 
anything for most people.

Furthermore seems like kernel and userspace tools have been improved to 
work more efficient and my netbook doesn't get so hot anymore, for me it 
stays most of the time at about 50 degree when doing office stuff and 
surfing.

kind regards,
