Ambient temperature
The temperature is measured with a thermistor.
4.19 SMB Hardware Monitor
In addition to the SuperIO hardware monitor you can also connect a SMBus hardware
monitor. This chip enables you to control different voltages, temperatures and rotation
speeds in legacy-free-designs where the SuperIO is not supported.

4.20 Serial EEPROM on SMBus
For testing purposes a serial EEPROM (4kBit) is connected to the SMBus. To avoid
address conflicts, the address can be selected with dip switch SW1101.
4.21 Serial EEPROM on I2C-Bus
For testing purposes a serial EEPROM (4kBit) is connected to the I2C bus. To avoid
address conflicts, the address can be selected with dip switch SW1102.
