OOOH my word, i just realised, that my pump was not running in my loop and it had been on and folding(100% usage on all 4 cores) for the last 24 hours. I am not to sure exactly when my pump stopped woring but it did.
It turns out it was just a lose connection in the molex connector because as i fiddled with it the pump came on and my temps instantly dropped in 20*c heaps. I obviously stopped the folding app.
Just look at the CPU max temps :0
I could feel the water in the pipes right there was pretty much boiling.
I won't argue that I wouldn't run a CPU at that temp for it's entire lifetime, but it shouldn't really cause any real damage to it, even if it ran for a few days at 100C. The sockets are tested/rated at 115C+ for 50 hours. Max suggested temp for the CPU from AMD is like, what, ~65C? Means the cores are probably near 75C. No idea how much a temp increase impacts the lifetime of a CPU, but doubtful that a couple days at 105C would kill a CPU. Now, if it were overvolted, then that's a different story.
