3930k low voltages-high temps on overclock?

post #1 of 8
Thread Starter 
So first of yes, I realize every piece of hardware is slightly different, be it the mobo, cpu, etc...

But I'm experiencing something that seems a little strange. I have a 3930k with a asrock extreme6 mobo. I am using a corsair h100 for cooling.

I have my voltage at 1.355v with a overclock at 4.7ghz and max temps in prime are 83. I am supper stoked at being able to obtain a overclock of that cailaber at this voltage but still the temps seem kinda high for that voltage. It is stable and temps on average in prime were 80, 83 was just the max.

Also not to mention these are max temps, so this of course is the outside cores that run almost 15 degrees hotter than any of the other cores.

Still, just seems a little high imo. Thoughts?

These chips do run a little warm.You may wanna try bumping your voltage down some.83 is a bit to warm for my taste.

Your H100 ain't really that good, for good results you need to go custom water.
So try to settle for like 4.3-4.5ghz and keep temps at max 70c I would say, so you don't degrade your chip! You will still kick every game out there even at 4ghz, so its not worries really! smile.gif

Yeah, that's definitely a little high. It could be a number of things. First what are the ambient temps where you are located ? and also what is the cpu temp at idle ? It could also be how your mounted the cpu, I would remove the cpu, remount, and reapply TIM.

I know a custom water loop is always better but I have zero experience with them and I was dropping $3k on my build, so was hesitant to mess around with one. Have done a lot of research in the meantime and plan on doing one when I get a 2nd 680. Wish I would have just went for it off the bat, but water under the bridge now.

Anyways, its not all that bad. I had the h100 setup with 2 140mm pushing, and the 2 standard 120mm pulling. So it should get some good airflow.

As for resetting tim, I used what was already on the block because I knew it was already high quality tim. That said, I don't think i should have any issues because it should have set in very nicely and evenly.

I backed it down to 1.34v and running prime atm. Same temps...

I have mine running at 4.4 gigs@ 1.29 volts and the highest temp i,ve gotten running intel burn test was 57c.so you could lower your voltage a little and see how stable you can get it at lowest possible voltage.Our systems are pretty much identicle.

Hmm, ill try. I was under the assumption that at a 4.7ghz clock, 1.38v or over was usually needed but I guess I've already proven that false lol.

Edit: Alright, got it at 1.31v @ 4.6ghz. Running prime for 15min so far with max temps at 75. I can deal with that. Hopefully it stays stable.

That voltage and speed on that chip with a h100 getting 83'C in prime95 is normal, actually pretty good.

4.6GHz seems more realistic with your cooling.
