I didn't quite get it either sorry, but like i said someone could correct me on the socket / cpu temp, but i know for sure that 61c is the safe maximum operating temperature on the cores.

I don't think that AMD makes any sense but that's the way it is. Read the AMD spec. Max Tctl ("core temp") is *always* 70. Max socket temp is around 61 to 64C depending on CPU.

Where's your source to that? I'm looking trough that link you posted quickly but i can't find anything about the Zambesi / FX Architecture?
Don't mean to be like that but it's important! Also the last update on that sheet was in Sep 2010

Thank you, so we go after core temp then while expecting a fault range of about 7-10 degrees Celsius on the CPU Socket.

That is the newest doc that's available from AMD ATM. It hasn't been updated for Bulldozer. But there was an official reply from somebody at AMD to the Linux kernel devs that the Bulldozer arch has the exact same thermal implementation as Phenom II.

From my understanding the core at load is accurate, so one could set a value for shutdown like 60c, apperantly its accurate under load but not at idle.

Also note, the safe max core temp for FX-8XXX and FX-6xxx/4xxx are not the same.
FX-8xxx is safe max of 60° IIRC
FX-6xxx/4xxx are 71°.

Well I've found out that the core itself won't shutdown until 90c because the silicon is made to withstand up to 97c so the 61 is more a safety net or did i get it all wrong?
