my gf's computer has been shutting off randomly lately so i came up to her place to check it out and it didnt shut off on me but one of the fans started to go nuts quite a few times, and this all started after i put in a new sound card she said...anyways when i heard the fan go nuts i shut the comp off and went into bios to look at cpu temps...which said 104c and i determind that was most likely the problem and now i dont know y its doin it so i dl'ed speedfan and cant figure out which temp1,2,3 are monitoring and im guessing core is cpu temp?? any help and what those are??
