Huge spike in haswell temps

post #1 of 6
Thread Starter 
I was stable at 4.4ghz and 1.26vocore and temps never went over 82c in realtemp using intel burn test on high, now I just tried intel burn test again and the tempos were hitting 97/98c and there was a whine noise coming from somewhere, why would this happen as like I said temps were fine a few days ago, using arctic cooler i30, checked to make sure cooler is screwed down properly and it is...
Idle temps are 29/30c and if it wasn't seated correctly idle temps would be much higher wouldn't they?

Also just thought i'd mention since the higher temps now when running IBT the times are much quicker, before on standard they took 40seconds or so to complete 1 run, now its down to 7 and the temps are higher, anyone shed any light on all this please? rolleyes.gif

You installed Windows 7 and started playing around with IBT and stuff. Later, you had everything about Windows updated and the first service pack is now installed. IBT can use AVX now. At the time of your first tests, it wasn't using AVX because it couldn't. Compare the GFlops if you have screenshots from that time.

Yeah it installed updates today and now the high temps, so what does this mean then shouldn't I have installed these updates have they ruined my overclock due to these high temps? What should I do?

Prime95 doesn't even go past the 75C mark, am I right in saying IBT shouldn't be used after these windows updates have been installed?

No, it means your previous tests weren't at full power of the CPU. biggrin.gif

Look around the forum. There's a Haswell thread, a Haswell OC thread, and threads about OCing Haswell with specific boards. From what I've picked up, you might want to avoid IBT and prime95. Using AIDA64's stress test is some kind of semi-officially endorsed test. It won't let temperature explode as much.

About what you should do instead, there's people reporting they crash a lot faster trying to encode x264 video or playing games. Even worse, a lot of people can pass IBT and hours of prime95 and will still crash in normal programs. This makes using IBT a bit pointless.

That's not exactly accurate.
There is no endorsed stress benchmark for haswell. You might pass AIDA but fail IBT, you should benchmark your system on any stress test available to make sure your overclock is stable across the board. AVX instructions are cream of the crop in terms of stress but depending on the situation; you might BSOD while simply idling because maybe your memory overclock is not stable.
