This is a passively cooled notebook, so there's no fan to control. They probably self-limit the CPU speed when the temperature gets high to prevent meltdown of the drive.
But I would like to raise the lower limit if possible, allowing the speed to bump back up at, say 58C rather than waiting for 52C as it currently does.
