Hello all! I'm running the Intel XTU stress test in the background right now on my air cooled I5 4690k @ 4.4ghz. I'm using a Zalman CN10PX heat sink and it is massive set up for pushing air out. First and foremost I'd like to thank everyone on this forum, you guys have guided me on my first PC build and will continue to guide me with everything else and I thank you for that.

So my question is, when I ran prime95 at 4.2 ghz after 10 minutes I reached 94C and I freaked out and stopped the test and shut my computer down. I went back into the bios and lowered the clock back to stock. Now what I'm saying now contradicts what I said up top, the reason being is that I did some research and found that Prime95 can cause fluctuations in voltage, sure enough my voltage was fluctuating the next time I tried it on prime 95 (monitoring with HWMONITOR). So, I'm using Intel XTU and the temps are remaining under 70c consistently at 4.4 ghz, am I safe to assume I'm going to be ok with this OC if it lasts IN XTU for 8 hrs? Or should I have a clock that maintains safe levels in prime95?

Edit: Forgot to add there are large fluctuations in temperatures running XTU it will go from 64C to 56c and so on is that okay? Last edit I promise, I'm running 1.250 Vcore Volts.

Prime95 pushes the cpu to it's max limit, that's why the temps are so high. Try playing a game like bf3 or 4 or crysis. Look at your temps under a real world situation.

That is what temps you will be running at, prime 95 is mainly used to see your max temps whereas other software like XTU are too try test the stability of your overclock. So if your temps are fine in a cpu intensive game then you're good to go.

-good luck

Please run Prime95 version 26.6 - http://windows-downloads-center.blogspot.com/2011/04/prime95-266.html

Small FFT's is the standard for CPU thermal testing, because it's a steady-state 100% workload, which means that it has steady temperatures.

Core i 2nd, 3rd and 4th Generation CPU's have AVX (Advanced Vector Extension) instruction sets. Recent versions of Prime95 run AVX code on the Floating Point Unit (FPU) math coprocessor, which produces unrealistically high temperatures. The FPU test in the software utility AIDA64 shows the same results.

It's not necessary to run AVX code for thermal testing. Prime95 v26.6 produces temperatures on 3rd and 4th Generation processors more consistent with 2nd Generation, which also have AVX instructions, but do not suffer from thermal extremes due to having a soldered Integrated Heat Spreader and a 35% larger Die.
