I agree its not real world
But gives a good idea on max temp, on a water cooled system I find that doing so is a good idea to test the system cooling capabilities. Though for me P95 will eventually give me the same max temps as IBT, just its not holding it at the max temp for long periods. P95 still takes quite a bit of time, when you can easily run 2-5 runs of IBT really quick when Overclocking to see if your somewhat stable then p95 or adjust settings. I tend to leave for work when running P95, So it is kinda nice to know that your CPU isnt going to get to hot while your gone because you already know the max temp from IBT. Overclocking a system to a point where to much heat will make the CPU unstable isn't always the best thing to do IMO. Still a good idea to heat test your PC. I find Air Coolers have a harder time with IBT, so that can also factor in.

I just ran IBT. My temps immediately shot up to 86C within seconds. Even after folding for over 48 hours, my temps are a solid 70 across the board. Again, you will NEVER have that kind of load on a CPU unless you are using LinPack. On top of this, there is no way you would have those kind of thermals, so it is a useless test to run. When you are approaching your maximum clock speed you can get, IBT is the last thing you wanna run. Yes, I still have wiggle room, but I don't want to run my processor at 90C either. Though if you have the cooling to handle the temps, then by all means, go for it.

If you are having heat issues, then a 1792 prime run should point these out.

Your also running ivy, I can see that without deliding it It can jump to crazy high temps like that. Even after lapping my CPU and heat sink I had to remount the CPU cooler a bunch of times to get a good mount I liked. IBT really exacerbates a bad TIM job, internal or external. Overall p95 and IBT give me pretty close temps, Even games like FarCry 3 will get my CPU pretty hot at times. Depends more on the setup and chip, as the 121+ on my bros old Q6600 would be around 5-10c hotter with IBT, even my old Q9550 was that way on my old SpinQ though the H50 was more evened out. IBT does get hotter, but for most chips not 10+c hotter unless something else is at play like CPU cooler or TIM.

Though Even I see 84-88C with IBT, my H50 sucks as a water block, I see no problem testing it at that temp for a few minuets. I have another CPU block I need to toss in, just havent felt the need to rip my pc apart, kinda hoping to get a 8970 soon so I can knock out two birds with one stone but thats not going to happen. tongue.gif

Can't rule out IBT all together though as it does hold its own as a stablity test, Some people like to hate on OCCT GPU with error testing enabled but I find it does a better job at stabilizing your rig then anything else. I'm one that can't stand artifacting or even games crashing, So 100% no matter what is something I enjoy. Even those White Dot artifacts make me mad. tongue.gif

So, I know I'm necroing here, but this is good thread meant to be commented on.

I really have to agree here. If your temps are fine in Linx, then you will always be ok.

And in my opinion, you're not stable. If you can't stress your cpu to the very maximum, and have it be ok, it's not good. I never go above 70C on IBT, and I don't crash. I am strongly for IBT.

 

Edit: although I say this, IBT has twice errored out on me. I will test more in the morning, but most likely, I'm not stable.

Who cares if you're not "truly stable", if your rig does everything you want to without crashing, it should be enough.
