What now? Don't suppose I can run the tests if the temps hit this high this fast.
Just let the tests keep running. If it goes any higher then 85 stop the test again.

Ran again, 2 cores hit 85, one went to 88, another to 86 and the last two to 84.
I don't think this is gonna work.

Ok. Then you need to figure out why they are getting so hot. Make sure your CPU fan is seated properly on the CPU. You could also re-apply some artic silver thermal paste.

In the interim, try opening your case and pointing a house fan inside and see if it keeps your temps down.

Well, I got no time to run the test now. Not enough time to set up and watch the temps. I'll try this later.

Ok. This might very well be the problem that is causing your crashes. Let me know what happens. Try the house fan first. That is the easiest.

What are your CPU core temps at idle?

Intel® Core™ i7-920 Processor

Your Tcase max temp is 67.9°C, add 5°C for max core temps 72.9°C.

Your CPU will throttle down before it gets hot enough to do damage.

Have you cleaned the dust out of the case?
All fans working?
Check if the CPU cooler is loose.

Dust has been recently cleaned out.
I've got one case fan offline since it took a little hair-beating and cost a ton to replace.
Far as I know, the interior is all fine.

I will go to the local shop and see what they have to do.

@mgorman: You're saying my processor might be overheating after working too long?
@Dave: According to CoreTemp, at this precise instant, the "idle" temps are 40 for the first core and varying between 35-39 for the other 3.

Yes. If it is getting to hot during a stress test then that issue needs to be addressed.

@Dave, correct me if I'm wrong.

You are correct.

A high temp when at idle indicates a problem, which, depending on the cause, can stay the same or get worse at higher CPU frequency/voltages.

Did you clean the fan blades?
They get a dust buildup that will decrease their efficiency.

Which case fan is not working?
Good quality case fans are normally not very expensive, check for another brand if the stock fan is pricey.
If you have only two case fans, one pulling air in and the other pushing air out, loosing one will definitely cause a heat problem in your case.
Be sure all wires are tucked out of the way as this can impede the air flow and cause heat issues.

Assuming you have the stock Intel CPU cooler, idle temps of 35-39°C are not unusual, replacing the case fan should lower that a couple of degrees.

The Prime95 temps are too high, should be below 70°C with a stock CPU cooler.
Check if the CPU cooler is loose, this is the #1 cause, it should be firmly in place.
Try pushing the pins in, this can take quite a bit of force in most cases.
The next step may be to clean and replace the thermal paste.

Let us know the results.

The fan blades have been cleaned last time I dusted the insides. The CPU fan with better care than the case fans.

I have 3 fans in my case. The case is ThermalTake and has a pair of proprietary fans. I've got a stock fan on the back and a new proprietary fan on the side. The one on top has not been replaced.

As for checking if everything on my CPU is placed properly and that: I don't trust myself enough to do anything to a CPU but cleanly replace it. I'll be taking it to a shop tomorrow and see what they have to say.
