CPU temperature fluctuating.

post #1 of 7
Thread Starter 
Hey guys, i am running a dual 120 swiftech radiator with an ek supremacy waterblock. My temperatures when stress testing fluctuates every other reading around 6 degrees C. I was wondering what this is from and if there was anything I could do about this. Thanks guys!

Well, it would help us a lot if you'd tell us what stress test you're using and a little bit about your CPU, like what it is, is it overclocked, hyper-threaded.

What you using to measure CPU temps? I prefer Realtemp ...
Sorry, I've never used Intel Extreme Tuning Burn In so can't tell you wether or not it would cause temp variations while running.

Cant say I have either.
Its definitley a non standard test, or at least one ive never heard of(dont consider myself a real guru in testing)

Anyway, some fluctuation is pretty normal.
6C seems like its pretty much within tolerances.
And as long as you arent spiking over the max temp you are comfortable hitting, you are ok.

I would try IBT, LinX, several ruins of Wprime 1024, or P95, and Realtemp just to double check that your readings are accurate. thumb.gif

Many stress tests cycle between different tests or alternate load between cores, which can easily explain temp variations.

I'm pretty sure that the IBT just uses short fft and uses all cores at once
