thermal runaway

[shedicus90]

recently i sufferd a major accident with my bedroom rig, it was beeing used to game on which is not out of the ordinary, borderlands 2 was the game in question when all off a sudden the room was filling with smoke and rig shut down. upon inspection an atx extension lead for cpu power had melted (4+4). everything seems to work and for the moment the pc is only using its own 4 pin although 88 is needed. the issue is that now my cpu runs idle between 56-70 which obviously is not normal. cpu is a phenom ii x4 955 not overclocked. what could be the issue and is it maybe related to the melting issue of the lead

And that is an unfortunate situation to have, as of right now if you are only using a 4 pin I wouldn't do anything intensive until you replace the connector for a new 8 pin. As for why it would occur it may have to do with the quality of the connection and the amount of Amps flowing through it, if it had a poor connection it could cause it to heat up or short out with surrounding connections to the point of melting.

ues this is what i belive too. i had similar happen on a differnt pc last year, but back to my temp issue do you think the high temps are related to this i am going to remount cooler and see if that helps but i fear the worst.

I don't think it would cause the sudden jump with the temps but a remount as you said might solve the issue. Give it a go and hopefully that remedies the problem.

If that 56-70 temperature range is in Celsius you're definitely running far too hot.  You want to keep the Phenom II below 62 degrees celsius at load; preferably in the mid-50s.

under no load it is in the 50-65 range somtimes. havent remomounted yet as i have been working on another project. usually best to keep them under 50 if possible also i ignore the temp given by core temp as its about 10c off on the phenoms amd also thats onlt the thermal junction will update when i do remount another theroy i have is that although the board survived maybe there is somthing not quite right

ok so i have since found out that the cpu is fine, i haveput it in another board and is fine, so im guessing either the socket is damaged or its a faulty temp sensor
