I thought upower doesn't influence the fan speeds. I would appreciate if
you'll point me for some differences between HAL and upower.

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.

It's just the new behavior and it's unusual :)
