I've looked up the thermal parameters for this CPU and it's a little confusing, but I think this is how it works...

- design target for the CPU is 130W
- real world consumption may go above this
- at 130W max temp for this CPU should be 69.8C

This is based on the CPU casing temperature, not internal die temp which the motherboard utility reports. I found an article which suggests the difference between those two points is about 18C, so that means that in theory I could go up to about 88C reported die temperature before there's potential for serious problems... I wasn't far from that earlier today!

I'm sure I saw another article which says that the cores are individually throttled (clock speed reduced) when they begin to overheat, but I can't find that now.
