Subject: Sony Vaio SZ61MN - no fanspeed control

Hi there!

In the process of havin multiple issues with acpi and drivers on my Sony 
laptop i stepped into another. The internal fan is always running at a 
fixed speed. If theres much CPU load it also speeds up. But i have no 
way to alter the speed. It always changes back to some sort of default 
value. Are there other ways to change the fanspeed than spicctrl with 
the sonypi module or direct echoing to the fan files made by the acpi 
stuff?

This could be dangerous for the hardware as it seems like it doesnt 
speed up to the highest level so the laptop gets very hot. Also it 
negatively affects the battery uptime.

Thanks!

regards

         sebastian
