Temps too high? Please help

So i just got windows 8.1 installed, used the Asrock pre-tuned OC @ 4.4 Ghz, and started running OCCT, had it set for 5 hours and it stopped after 5 mins because it states that core #1 was over maximum value @ 86 degrees Celsius. I used the pea method on my 4770k with a noctua nh-d14. Do these temps mean i need to re-apply the thermal paste, or should I delid my cpu, reapply paste to the die and put the IHS back on and then redo my thermal paste for the cooler? Or should i just drop the OC to 4.2 ghz and try again?

reseating your heatsink may help but, Haswell chips are known to run extremely hot and 4.4GHz is already somewhat on the higher side of overclocks on Haswell CPUs. i don't find anything odd about your results.

i dont think there's a reason to delid unless you really want to overclock that much higher. also, you have risks when you delid along with voiding your warranty with Intel.

Ok, I wasn't too keen on the idea of delidding, but I'm new to overclocking and want to make sure I'm not going to damage anything and I am unsure as to what kind of temps I should be seeing @ 4.4 Ghz. I might step it down to 4.2 Ghz and go again to see if i can keep it below the 85ish temp. After looking at the hot spots on a haswell, i was thinking maybe re-applying the paste using the line method may be a better way to go.

i did the same exact thing on my 3770k, used a line method with artic silver 5 TIM and it did show better temps, nothing too significant but, still better.

try an keep your temperatures under 70C-72C for 24/7 use (so gaming and any other daily programs you use). it's ok to hit high temperatures like 85C just briefly when stress testing but, temperatures like this can start degrading your chip if it stays high over a long period of time. same goes for high CPU voltages, try an keep it under 1.3v for 24/7 use.

also, you should use Intel Speedstep which can be enabled/disabled in the BIOS but, stock settings should be enabled; it'll clock your chip down to low voltages/speeds when idling so it's not constantly running with higher volts/speeds/higher heat.

can't really say there's a general temperature for 4.4GHz cause every chip is unique, some will hit 90C+ @ those speeds and some will be under 80C. of course, something like a custom water loop will show lower temperatures but, the Noctua cooler you currently own should suffice for 4.4-4.5. :)

I'd try a remount..and put the Vcore in check.
It's probably set to auto and giving more voltage than it needs.
The way to do it is set offset to 0 or less
..and lower VRIN

So i lowered it to 4.2 Ghz, been running for 40 mins now on OCCT, and it has yet to peak over 76 degrees Celsius. I haven't even reseated the noctua or changed the thermal paste yet. It may be good to go at 4.2

sounds solid, remember, just cause you peak in the 76C area in a stress test doesn't mean your programs will even get close to those temperatures.

if you feel like 4.2 is enough, you're ready to test a little bit more and finalize your overclock. one example you can try is slightly lowering/raising voltage to see if there are any significant changes in temperature or performance.

let me know how it goes :)
