Intel Core i7 4790k Temps During IntelBurnTest? 100c...

I have a Intel Core i7 4790k with a Hyper 212 evo cooler on it in a new system I just built.

I don't know much about temperatures but thought I would test my temps to make sure I got the cooler on correctly with enough thermal paste to do the job.

When I run IntelBurnTest v2.54 and use Core Temp 1.0 RC6 my temps shoot up to ~100c and Core Temp starts warning me...

I am guessing this is a problem...

At idle the temps sit around ~33c

Did I do something wrong? Should the system be able to stress test and stay at lower temps?

When you use IntelBurnTest you are of course putting the CPU in high pressure, but those temperatures are not normal, usually the i7-4790K stays at about 70ºC. Are you sure you assembled the CPU Cooler correctly?

EDIT: I did some research and those temperatures are not that uncommon. Take a look at this article, it might me helpful. http://www.tomshardware.co.uk/forum/id-1800828/intel-te...

Anyways, 100ºC is not safe at all and will shorten your CPUs lifespan. Do not overclock the CPU over the 75/80ºC as it may be harmful.

I thought I did... F**k, really don't want to have to pay someone to verify ><

Make sure to set voltage on static/override mode. 1.2v should be enough, 1.25v at most. Mine needs 1.13v at 4.4ghz. If that doesn't fix the problem, reapply thermal paste and make sure everything is mounted properly. It's really important to not apply too much thermal paste, too. So if you want to be on the safe side, take a picture of how it looks and upload it for us to look over.

Upon looking around at thermal paste application pictures I believe I did apply too much paste...

Also, in Core Temp is the "VID:" location where it shows voltage? It shows ~1.4504 when I start the IntelBurnTest and 0.96 when idle.

Yeah it is and 1.45v is way too high. Make sure to go in the BIOS and set it on static (NOT offset or adaptive) 1.25v. That should be more than enough, from that point, you can go lower until you get bsod's at full load. If you reach that point, give it a bit more and it will be stable. To quickly determine the "right" area you can decrease from 1.25v in 0.02v steps, if its not stable anymore, increase by 0.01 and if its not stable then increase by 0.01 again, then it will have enough for sure.
If you think you applied too much thermal paste, clean off the thermal paste that is on now, apply new one and then remount the heatsink. I once applied too much too, resulting in 80C instead of 60C in torture tests.

I removed the Hyper 212 and cleaned off all the thermalpaste with ArctiClean.

I was having a hard time with the Hyper 212 mounting so I installed the stock Intel cooler which already had thermalpaste strips factory placed.

@ Idle my temps are hovering around 40c but when I initiate the stress test my temps shoot right back up to 100c

UPDATE:

So I returned and repurchased the CPU and the cooler, now using a thermaltake cooler that's essentially the same as the previous (sold out of the 212)

I installed the new processor and the new cooler and I am getting

~20c idle according to "Real Temp"
~30c idle according to "Core Temp"

~90c During IntelBurn Test according to "Real Temp"
~100c During IntelBurn Test according to "Core Temp"

*I also updated my BIOS earlier to the latest version of which seems to have had no impact.

I already told you what the problem is. You can have the best cooler in the world, if you let your chip draw 1.45v vcore it's going to burn nevertheless. Fix the voltage in the BiOS to 1.2v, if thats stable go lower until it's not stable anymore.

I apologize, I forgot to mention that when I updated the BIOS the default for the CPU vcore voltage was changed to 1.249

I will adjust the voltage lower as you stated to see how low I can get it, just to confirm; "CPU Vcore" is the correct setting to adjust yes?

Yeah it is. I had the exact same problem as you when I was building my i7 4790k, temps spiked to 90s and were still raising. Lowered the voltage from auto to 1.2v then 1.18 etc until 1.13 and found the temperatures constantly falling until I'm now at 65-68°C max. during AIDA64/OCCT. As I'm not familiar with IntelBurnTest another possibility might be that it uses AVX2 instructions like prime95 version 28. I couldn't get my temps stabilized with prime at all, because even though I set the voltage to static 1.15 it would still draw up to 1.5v under prime.
Mind getting prime95 26.6 http://www.mersenneforum.org/showthread.php?t=15504 and doing stress test again?

Yes it's likely the voltage, but it could be your heatsink mounting as well. Just to be sure - you said "enough thermal paste to do the job." What paste are you using? And exactly how much?

Five important points:
1) ALWAYS USE GOOD QUALITY THERMAL PASTE
2) DON'T use very much at all
3) Have a good spacious case with GOOD air flow and plenty of fans
4) Consider your ambient or room temp might be affecting things
5) Relax - this is supposed to be fun

I use Artic MX-4 (which is wonderful) and only a small dollop about half the size of a pea. Maybe about equal to two BBs. Put it right in the center of the die and then let the heatsink/cooler flatten it out. I agree that the Hyper 212 EVO is fine and you should not be that hot. Post your full system specs.

Although I have a better cooler (Corsair H80i) my i7 4790k only hits about 75C under Intel Burn Test. Don't over tighten (*hugely important), BUT...make sure you are tightening the cooler down enough to get it tightly fitted against the IHS. Sometimes out of fear of breaking something, people are afraid to screw it down enough and there ends up being a small gap (or gaps), causing the entire surface of the IHS to not be making full contact with the water block, or in your case, the cooper plate. That Hyper 212 EVO is a fine cooler, but don't you dare use that crappy Intel stock heatsink. It makes a better paperweight than a cooler.

My idle temps right now (according to RealTemp) are 25/21/25/26. My voltage is at 1.202 right now (it's on "Auto" in BIOS) and I have "Enhanced Turbo" on also in BIOS causing all four cores to run at 4.4GHz - 24/7. Even under heavy load while gaming (BF4, Watchdogs) I'm only getting into the mid to high 40's (C). And my system has been on for about 5 hours this morning.

Take a deep breath, get some MX-4 and start over with the 212 EVO. And get it screwed down nice and snug. Then go outside and throw that POS Intel heatsink as far as you can.





I have a first batch 4790k (L3) and have no temp issues at all. Yes there is a chance you have a bad proc, but its a very small chance. Start from scratch and remount. Then test again.

Updating the BIOS version decreased the default voltage, I then adjusted it even lower to 1.200v

Here are my results now...

The temps still spike up high as hell at the start of each of the individual 10 tests that are done by IntelBurnTest but now it's only for a half a second that the temps spike like that and then they even out around 70c for the majority of each test.

1.200v Idle after reboot


1.200v During 9/10 IntelBurnTest

Dont worry I feel your pain lols, I was at this 3 weeks at least, same problem at 100c.
Only way I fixed mine was by lowering VID to 1.05V at 4.0ghz no turbe for 75c at least.
With evo too, since older coolers were giving me 100c as well, 4 of them.
Mine was auto clocked out of the box at 4.4ghz all cores, this wat gave me high temps 100c.

Also you only need a thin layer of paste for it to work effectively.
And that cooler is a pain to put on, if you dont line of the that little knob in center.

I had an issue. My temps idled at 23-30 c. But any test would jump it to 80-100c. Come to find out, due to my own stupidity, I didn't line up the xclamp on the back the right way, I didn't notice the notches. Not it doesn't get over 66c.
