Hey all, my first post here! Before I shoot with my questions I would just like to say thanks to tom'shardware! Anytime i have had questions, I hop on here and see how the community is quick to help out. So thank you all!

Anyway, about a month or so ago I built my new baby seeing as i was rigless. Its my third build so i had enough experience to get it the way i wanted it. Heres what i started with:

MSI Z87-G45
Intel i5 4670k
CM 212 Evo
G.Skill 2 x 8GB 1866 DDR3 ram
Evga GTX 660 non ti
Seagate Barracuda 3TB HDD
Evga nex750b PSU
Sony Optiarc Disk Drive
NZXT Phantom 003RD Case

It was a good start. I picked up an Asus Maximus VI Hero used it a bit but hated the bios so went back to my MSI board. Then I delidded the 4670k and it worked well, dropping temps a whopping 12C, for two weeks then no signal to the monitor! damn! oh well guess i ruined those caps. So i orded an i7 4770k as well as a Samsung 840 Evo 120GB SSD.

I reassembled with the 4770k last night and reloaded the OS and all drivers. Its all working great! one problem though.. While encoding a little movie i watched the temp climb excessively high 83C. This is at stock clock and vcore! So ran prime95 blend and it peaked about 87C within a minute. Small ffts pushed it to 94C within seconds and overheat protection shut it down seconds later. So this morning I reseated the cooler with a little less TIM (using the CM stuff that came with) and made sure it seated nicely. Booted up and only saw a ~2C drop. WTF!?!?! this is way too hot! so what next? btw voltage at full load jumps to 1.3009v. I suppose i can manually drop voltage with an offset. This chip seems to be at the low end of the curve.

4670k overclocked to 4.1 at ~1.26 ran full load with small ffts at about 84C before delidding. after it sat right around 72-73 MAX!! That chip also needed excessively high voltage to reach higher clocks. Guess Im unlucky!

Edit: Also idle temps are 33, 30, 31, 29

Please, be patient.

How did you reseated the cooler? What cooler is it (brand and model)? Did you apply thermal paste?

4770k's run really hot, you usually need a high end after market cooler like a h80i or h100i too get decent temperatures and to overclock at all. If your running a stock cooler and prime 95 I see that as being usual.

If you want to extend your CPU life, reduce it max usage avaiable: go to Control Panel>Energy Panel, select the High Performance plan, open it settings, open Advanced and look for the max, min usage. Set min to 5% and max to 80%. Save and restart your PC.

Why would you ever do that.. buy a high end CPU and take off 20% of the performance? He shouldn't have to do that this is a high end part and should be able to go above and beyond the 3.5 ghz even.

Yes, but if you read in the first post, he is with temp problem. So let keep things in cold waters until fix it.
He didn't even answer if he use thermal paste and in wich direction he seater the cooler.

Thanks! Sorry for my impatience. It is a Cooler Master Hyper 212 Evo as stated above. Using the Cooler Master thermal paste and applied it just as i always have, similar to the pea fashion. Cooler is oriented perpendicular to ram, horizontal in case, exhausting heat out the top. I reseated again twice this afternoon first atempt I saw maybe 1C drop (so negligible it was hard to even tell) then the second was identical. This is ridiculous! I will not reduce the usage. Period. Why would anyone spend top dollar on one of these CPUs just to dial it back?! Ambient temp is 23C, and the case has the side off.. so exactly the same, 23C. I considered trying the heat sync that came with it but i figured it would make it worse.. and louder! Oh and thanks again!

To be honest that's not really a good CPU cooler, if you can afford it I would suggest getting a H80i+, if your overclocking or thinking of doing intense programs then you'll need it for sure, thats probably why even after re seating it you only get 1C difference, with my H80i and my 4770k it has the same ambient temperatures as yours at around 23C but then jumps to 60-65C I believe when running intensive programs. These chips simply run really hot and with this high end CPU you'll definitly need, plain and simple a high end cooler to go with it. If it's in your budget go for a H80i+ (that's when water starts to be better then air)

Lman, I appreciate the support but read more, preach less. H80i will not make a noticable difference on 4770k compared to 212, a few degrees maybe. I may be wrong but either way thats not the point. This processor is at stock settings and I tried encoding the same movie from earlier and hit 92C then it shut down thanks to overheat protection set at TJmax. THIS IS NOT OVERCLOCKED!! This is 3.5Ghz @ 1.3009v!! Im considering trying to rma the cpu now.

Edit: When running prime95 small ffts, power goes over 104 watts. These are rated at 84W and ive never seen a processor hit its rated power consumption. my i5 overclocked to 4.2 maxed at 77W... not sure if this makes a difference but seemed strange to me.

To be clear I've ran at least 5 different Haswell builds all with the i7-4770K and all of them with a Hyper 212 EVO and have never had any issues running at 4.5 GHz on all cores and NEVER went abouve 68C even after running AIDA64 for minimum 3 hours straight on each and every card. I also NEVER let the CVoltage over 1.25.

Yeah, I would send that chip back. Originally I would have thought perhaps you are using too much Thermal paste, but as you say, you have done builds before without any heat problems.

With the 212, I always run them so the air blows towards the back of the case (and towards another exhausting fan). But again, this won't be causing your problem when it is that bad.

Go into bios and manually set voltage to 1.15v


Try to boot into windows, - if you cant go back into bios and add .01v till you can - Run your tests.

If you can log into windows at 1.15v no problem and can pass the tests without a 124 error or freeze then you back into bios and lower voltage by .01v and repeat tests until you get instability.

Add .01v till you get stability back and ya have proper voltage for your cpu.

1.3v is LUDICROUS high for stock speeds.

This is much more helpful, though it didnt help the problem much. I dislike setting a fixed voltage for obvious reasons, and any voltage would jump to 1.3009v everytime. So i just used an offset to bring it down to 1.1885v, it might be stable slightly lower but dont have time to test for extended durations. 3.5Ghz @ 1.1885v and core temps still max at 84, 83, 81, 76. Ill call the place i got it from today and see if i can return it. Thanks for the help guys! Ill post up the outcome to help others.

Seems like an issue with mobo settings and not your cpu.

Are you using adaptive voltage?

cause its a well known glitch with benchmarks.


You should only ever bench with manual settings.
