Máy của bạn bình thường, bạn không cần quá lo lắng về cái AUXTIN đâu
AUXTIN is can say that it's probably something that's disconnected/not supported or a reading for your power supply. But in any case it's a wrong or false reading, all the time it received by people. One of my sensors reports/measure below freezing. Don't worry, may be none of your components are at 125C.
According to me AUXTIN is called presumably Aux T (@) In. It stands for Auxiliary Temperature input as same as auxiliary entrance temperature. And with it not closer to specified sensor temperature's is called in these program. And, however, often mistaken is given in selection. The temp reading you have is not that much in concern, may be you blow a fan on the motherboard, which make temp down. Hope this might fix your problem
