Hi Chunhao, > When the fan divisor adjust itself automatically step by step, Should > the fan limit keep the original value? Yes it should. It is already prefered when changing the divider is a manual operation. It becomes a requirement when the divider changes automatically. > It seems that in your driver, the fan limit value will also change with > the fan divisor like mine? No, the fan min value, expressed in RPM, is preserved. > Could you tell me the exact purpose of "old_min"? It's there to prevent writing the new register value if it happens to be the same as before (which will basically happen if the divider was not changed - I guess I could have tested the divider value instead for a similar result. -- Jean Delvare
