I thought upower doesn't influence the fan speeds. I would appreciate if you'll point me for some differences between HAL and upower. >> I did notice that the fan speeds differ from the LiveUSB system now (e.g. >> for the same temperature LiveUSB fan speed is higher - so the CPU temp is >> lower). >Lower fan speed = less noise and less power consumption.
You know, right now the fan speed is much more aggressive and I have no idea why it changed. I just wonder if there is some kind of config for fan control. >So why are you complaining? :-)
