Notes:
1. The ambient temperature and the CPU loadings a ect the system an rpm. There ore, the higher rpm will
generate higher an noise (dB). The smart an o ARTiGO A1250 system runs at lowest speed (de ault) at
25°C room temperature and when the CPU loading is less than 60%.
2. As the operating temperature provided in the speci ications is a result o the test per ormed in VIA’s
chamber, a number o variables can in luence this result. Please note that the working temperature may vary
depending on the actual situation and environment. It is highly suggested to execute a solid testing and
take all the variables into consideration when building the system. Please ensure that the system runs well
under the operating temperature in terms o application.
