OK I ran the standard and high tests:
standard: average temp 72 high 77 time taken 76s
high: average temp 80 high 86 time taken 193s
Not sure about running very high given that in high it was already running mid 80s at some points on some of the cores?
Just to say the tester said that the tests were passed in both cases and indeed the PC remained responsive throughout.
Again the fans spun at the same speed throughout.

I'll give it a go, do you have desk fans or something to point at the case?
OK did it passed:
average temp:90
highest temp:93
time taken 391s
Okay thanks, we need to be able to run the Prime95 tests though.
The temperature should be okay, if it stabilizes just above 80*C.
arghhh it kept climbing took a few minutes but ended up mid 90s at which point I felt I had to stop it.
This is using the HwinFo64 rather than speccy to read the temperatures.
HwinFo64 seems to give higher temperatures in general than speccy
OK tried it quickly CoreTemp and HwinFo64 give the same results temperature wise.
I also tried running the prime95 again quickly again and found that it went back to 95C, before I got cold feet and turned it off.
However CoreTemp also lists the max possible temp for my processor which is 98C.
It does however say the core should be kept at least 15-20c below that!
CoreTemp also has a feature where it will shut off when a given temperature is reached.
Do you think it would be OK to run it with the safety set to 97C?
Assuming the above idea is OK, how long should I leave the computer to cool down? Should it be overnight or is 5 mins enough??
I would least give it an hour, which test are you running? In my opinion, I would try the Small FFT's first.
I wouldn't let it go near the maximum temperature, are you using the stock fans and heatsinks? Have you checked the thermal paste for the CPU?
The temperatures recorded were using small FFT's.
The computer is as I received it, it was built by overclockers and I have not changed anything, apart from taking the panels off.
I have not tested the paste, indeed I am not sure how to test it. But the computer is less than 18 months old?
Seems to me that the most obvious suspect if overheating is to blame is that the fans not speeding up when the CPU is under load. (Although I am no expert!)
But also just to be clear the crashes I originally posted about, occurred when the PC was not under load.
To check the thermal paste, you would need to take out the CPU and then check it - Applying Thermal Paste - iFixit
The dump files seem to point towards a error with the Level 2 Cache, but it' always best to run stress tests to confirm it, unless you have or know anyone you could borrow a CPU from to swap with?
Do you know if the anything is overclocked?
