There appears to be a dual usage register "CPUFAN MODE Register / CPUFAN TOLERRANCE Register - Index 02h (Bank 2)" and the actual limit is readable in (CPUFANIN) Fan Count Limit High-byte Register - Index 3Ch (Bank 6), but that's read only. Maybe it's better if we handle the fan lo limit within the driver rather than through the chip.
