x4 965 hitting 100*C

i just started playing ArmA II: Reinforcements and after about 15-20 minutes, my computer would shut off immediately. i figured it was some sort of heat issue so on restart, i went into the hardware monitor. it showed my CPU was coming down from 98*C (assuming it hit 100* and that's what triggered it to shut off). i'm not overclocking at all. i read that this cpu should be running between 55*C-62*C. at idle right now, it's running around 68*C-70*C, which is still too hot. i'm using the stock fan and heatsink that came with the cpu and i made sure that it is operating (100%, ~3500rpm). i'm pretty sure it's not an issue with my case because my 5970 isn't overheating at all. is the stock fan and heatsink just crap or what else could be going on here?
 
Did the clips pop off? Something is not seated properly on your HSF. Take it off, reapply thermal grease and re-seat the HSF.

Probably you need to reapply quality thermal paste and then reseat the fan and heatsink.

^ This.

I had heat issues not so long ago and it turned out to be a bad fan header on my mobo where the pump for my cooler was plugged into so it wasn't cycling the water to cool it.

This lead me to the discovery that the newer stock AMD heatsinks work GREAT. I'm ~40c load w\ the stock cooler on a x4 620.

If you're getting to 100 something has to be wrong. Either your thermal paste is toast or perhaps the heatsink isn't sitting properly on the cpu.
 
i cleaned all the dust out of my case, fans, etc... (some pretty big chunks). reapplied thermal paste and reseated the heatsink/fan assembly. it's now running in the mid-high 30's and i got about another 250-300rpm out of my CPU fan. i'll keep an eye on it, hopefully it'll be ok. thanks for the input guys.
 
yeah, it concerned me to say the least haha. but it's all good now, mid-gameplay, the CPU was in the mid 40*C's so i think it's safe to say the problem is solved. thankfully.
 
....that is freaking incredible. Didn't know these chips could run that hot without immediate and permenent failure. You should've got a screenshot!
 
Gaming load makes my 4.3 2600k to reach nearly 60c with my h100 and quality thermal paste. Amd probably runs cooler. Surprisingly there are no amd fans who complain about intel running hotter 😛
 
OP 100C is well beyond the death zone for a Phenom II. Count yourself lucky and never let that happen again. Keep an eye on your temps and maybe get a bigger HSF just as a precaution.
 
yeah absolutely. honestly, i'm shocked it took 100*C to force the shut down. definitely keeping an eye on it and will routinely clean out my PC. still in the 30's so i'm good so far.
 
Good to hear it's still running like a champ. Sounds like you ironed out the problem and are good to go.
 
AMD recommends not going over 62c, but that is not the max temp the chips can take. K10.5 chips have been known to run near 70c without any stability issues, but a little higher usually trips the motherboard's temperature safety feature.

This is actually untrue, an AMD chip should be easily able to survive up to and beyond the thermtrip limit on the device.

Much of the time, however, over-temp is caused by the CPU drawing a massive amount of current for some reason, which can fry either the CPU pins or the motherboard.

It's electrical current that kills chips, not temperature. (Although higher temperature does lead to higher current draw)

So why does AMD say that the T-max is 70C or whatever?

Because if you operate the device beyond 70C, it will draw way more power than the TDP

*edit* And also because it will degrade the device over time.

I can probably expand further if you're interested:
AMD specifies a TDP, and OEMs that design the thermals expect the power draw not to exceed the TDP.
TDP is a function of operating temperature: If you operate your device beyond Tcase Max, it will draw more power.
If the thermals can't handle that extra power, it results in thermal runaway.
More temperature => more power => more temperature => etc, etc.
