I've just built myself a Core 2 duo computer. Ambient Temp is around 28ºC. Every temp seems to look fine on CoreTemp, like System 39ºC CPU 41ºC AUX 71ºC HD0 41ºC HD1 41ºC Core0 32ºC e Core1 33ºC. All these are Idle.
What is scaring me is the Aux temp. It's very high, but I don't know where this sensor is. So I wonder if any of you know if this is normal or where the sensor is placed.
Thank you for you responses, APT403 e C_deck. I waz a bit worried, but i've noticied that it's a glitch too. When I turn fan 3 to 35% (not more not less, 35% exactly) on Coretemp the temp gown down to 37ºC. And once it hit -42ºC, followed by 6ºC. This is on 28ºC ambient and all air cooled.
