At my wits end - 3930k help

Ok, so got my 3930K installed, but I have spent the last 5 hours re-seating and swapping coolers, between Zalman Flex with 2 fans in push/pull and a Kuhler 620 with 2 fans push/pull.

Just running at stock, my temps are hitting over 70C, and it's fairly cool in here this morning.

I know these chips run hot, but this just doesn't seem right. I maybe expected this with the Kuhler, but not the Flex - it may not be an ND14, but it is a very good cooler, and it's done a super job of cooling 2500K and 3820, both OCed.

Surely this isn't normal?

Edit:
Oh, when I say stock, that's 3.2GHz with 3.5GHz turbo (shouldn't that be 3.8?), using 1.19V according to cpu-z

Definitely something wrong. My new 3930k is 30c and under at stock.

If you are sure it is not the board, maybe time to send it back.
 
Sure it's not the board - had no temp issues with 3820...

Going to have another go with the Flex in - currently got kuhler in.

Hate taking things apart so much - just increases risk of damaging something :(
 
Good luck sorting it out.

The important thing is the load temperature.

Is yours 70 degrees at full load?

embalse's 30 degrees sounds like the idle temperature so make sure you're comparing like with like.

Re-seat the heatsink?

Did you even read the first post?

Have done that over and over, also trying 2 different coolers for several hours now.




Anyway, got the Flex in, and peaks at pretty much exactly the same as the Kuhler. And I know the Flex is a better cooler.

Just doesn't seem right.

If this thing is peaking at 70 (using IBT very high), then it leaves me pretty much no OC headroom.
 
Whats the airflow in your case like?
Does seem very hot as my 2600k maxes out at 68c @ 4.5Ghz with 1.320v through it.

Sorry mate but I just glanced on my phone so missed it.

I was getting similar results to you until I changed my cooler and decreased the stock voltage to my CPU. Now it's 60C on load with the H100.

I've also concluded that my CPU just runs hot.

And I apologise if I was a bit snippy. Had 4 hours sleep, and mucking about with this for hours done nothing to put me in a good mood.

What are you using to check the temps? Sounds like they are being reported incorrectly to me.

HWinfo64 and CPUID Hardware monitor both reporting same - not run at same time though.
 
Might be worth trying Prime95 instead as well, IBT seems to be a bit weird with my 3930K I get higher temps with 6 threads than 12.
 
CPUID hardware monitor is reporting idle on my cores from 36 to 45. This is with speedstep dropping to 1200MHz and voltage down to 0.82V. Struggling to believe this.

Aida64 however is reporting idle from 27 to 35 across cores, which seems a bit more what I was expecting.

But what do I believe?
 
Looks like max I am seeing in Aida64 with IBT very high is a peak of 64. That looks like on two cores. Other all appear a good few degrees cooler.

Still not sure which temps I should be believing.

Can you give him an idea of your full load temperature so he has something to compare to?

Running stock on full load maxes out with Prime95 @ 58c.

That said it was and still is a pain to get good temps unless you go agua.

I think a lot depends on your case/airflow plus the cooler/fans.

I reseated a couple of times to make sure it was seated well.

I started with a H80 which died on me.

Then used a Megahalems with one 1000 rpm fan. This resulted in high 60's temps.

I then fitted two Scythe Gentle Typhoon 1850 RPM fans and this brought the temps down to max out on full load @ 58c, but this is still not perfect as I have high profile ram so the cooler does not get the full force of the fans as the fans sit higher than the cooler.

Am going to try a Armageddon next week, not because it is any better at cooling but beacuse it will fit in my setup and clear the ram.

Will post back with results

Thanks for the info embalse.

Have decided to trust Aida64, because the temps the others are reporting just don't ring true to me, especially when it's telling me it's idling over 40 on almost every single core.

So now seeing if I can get 4.5GHz. So far, looks like I might be able to do it sub 1.3V.

Need to do whatever I can to keep temps down.
 
Eyetrip these cpu run hot! Try using coretemp

Im on custom WC loop with essentially a quad rad and my temps are at stock

Idle: Low 30s
Load: 50c

So with you only using a 620 and the zalman cooler i wouldnt be suprised if 70c load is normal. Also its normal for a couple of cores to run a little hotter than the pther so dont bother reseating thinking you have got a bad mount!

If your boards got LLC you might want to whack it up a bit to kill of Vdroop, which i found to make my overclocks more stable and at lower volts. Im @ 4.8GHz @ 1.35v but i think ive got a pretty good chip.

If your into overclocking might be worth buying the intel overclocking warranty for £20, some may say its a ripoff but it gives you that peace of mind knowing your not going to blow you £500 chip up and be out of pocket.
 
3930k / H80 / Asus P9X79 Pro here, stock temps range from 26 to 32 idle. At 4.5 / 1500 MHz 1.325 vcore, it idles 27 to 34 and on IBT very high from 63 to 75 peak, but note that 25% LLC brings vcore up to 1.344 occasionally. From what I've read, these are decent ballpark figures, you may do better on the voltage.

It's a pity I just retired from phase-change cooling. Imagine a SS or even a cascade on one of these. The way the temps / volts scale say that even mine would be awesome :)

As I've mentioned elsewhere, I simultaneously ran 12 BOINC instances at 100% on the hyperthreads, ran a couple of the graphics from the BOINC jobs, had a load of other clutter like CPU monitors, task manager, browsers etc running, and I was playing Eve Online switching between two client instances yesterday, hours and hours with 100% CPU. 65C peak, I couldn't tell there was any load at all from a user pov apart from the H80 fans being uppity. That's why I love this chip :D
