Heat usually isn't the problem, the temperatures usually stabilize in the first few minutes and stay in that general area until you stop the tests. Unless you have an awful case/heatsink.....

EDIT: forgot to mention you are going to get 100 different opinions on whats stable. the bottom line is you determine whats stable. everyone uses there pc alittle different and runs different programs. if its stable enough for you to use it, does it matter if you only pass 6 hours of p95 but not 7?
^ this.

There is only one reason typical users would want or need to stress test 12 hr+. OCE-peen. If you're running mission critical stuff you won't be overclocking. If you're folding or using some other distributed computing application, you'll want to stress test until you're happy.

All stress testing does is prove that it can run that particular stress test. I've seen plenty of computers that have been stress tested for days but still crash to normal applications. Stability is a pipe dream. Even computers that aren't OC'd aren't 100% stable.

How do you get e-peen by determining that your computer is unstable?

for a quick and dirty p95 test

do custom, 1344-1344, 90% ram and 1 min for each test. Do that for 20 mins, then do same but wwith 1792-1792.

Never could understand 12+hr prime 95 test. No normal programs hit your processor as hard as a stress test. I look at it in real life. Do drag racers build the cars to keep running all out 24hrs or just for that time it needs to be on the strip? I say evaluate your usage and stress by that. I game for about 3hrs a day so I only stress 3hrs max. If you comp is going to be on 100% of the time and using 100% of the power 24/7, then I see that's the only time you should be stressing more then 6hr+. If you going to only play a few hours a day, then thats how much you should stress, anything else is just a waste.

In my experience IBT will catch it pretty fast, like in 2 minutes.
12 hr Prime is overkill for me.

It doesn't work like that.
If system is unstable,it can crash anytime.
In your example,you play games a few hours a day.So you test your oc also few hours a day.But that's wrong way to do it. Why ? Because system stability has nothing to do with how long you play your games.So you test prime95 for 3 hours and it passes. You conclude your system is stable,but yet it is not. You continue to use your pc,and one day it can crash/bsod/restart only 5 or 10 or whatever random number of minutes after you start your game
just because system is stable on prime for lets say 3 hours,it does not mean it will be always stable for 3 hours in games or other software
So even if you want to play games only 3 hours,you must run prime ( or other testing software ) for a lot longer to see if you system is stable or not
How long you play games or use other software has nothing to do with how long you should run prime.System instability is unpredictable.3 hour of prime stable can crash within 5 minutes next time you run prime again.Or in games or any other software

You really don't need to bold to make a point. I've done the stress test theory that I posted and never had a problem with it. You fail to realize that BSOD's can happen at any time regardless of overclock or not. Just because I do my test different then yours doesn't mean I'm wrong. You have your methods, I have mine. Yours has never failed, neither have mine. I never said that this is wrong, I said I just didn't see the point and offered another alternative. It's up to the person who's overclocking to decide which route they want to take. Last time I check, OCN was a fair site, not a do it my way or your wrong site.

You never had a problem with it only because if you ran prime for 12 hours you would not get an error
I am talking from experience,on my different cpus,both amd and intel,3 hours is not enough. 3 hours tested overclocks failed within 30 minutes in games,sometimes even within only couple of minutes.
I am just saying,you need to remember,unstability is not predictable,you can't say "ok I ran prime for 3 hours and now every game need to work for atleast 3 hours too not a minute less"
If you think this is not correct,then indeed you are wrong

3 hours seems like plenty to me, Prime95 punishes the crap out of your CPU, most games don't beat up your cpu like prime does
