AFL2-W21A/AB-H61 series panel PCs are designed with light fanless technology. The
light fanless technology utilizes K-type thermocouple temperature sensor to detect
environment temperature and control fan operation, enhancing system stability and
remote environment control. The relative errors between the detect environment
temperature and the actual environment temperature are no more than ±5 degrees. When
the environment temperature is lower than default temperature setting, the fan will be
switched off, showing the advantage of quiet and dust free from fanless mode. While the
environment temperature is higher, the smart fan will be turned on to speed up heat
emission. The default temperature is 32 C and the setting can be adjusted in BIOS. See
Section 7.3.9. The systems can be easily implemented in the working environments that
require quiet and avoid dirt, like clean room, indoor HMI, and hospital.
