Kaby temperatures?

Got around to installing my 7700k on an Asrock Z270 itx tonight using a dark rock pro 3 cpu cooler. Upon switching on the bios read 56c which immediately concerned me but it did not rise.

Going into windows hwmonitor showed a cooler 26c at idle and I ran some stress tests using the mobo std profile of x45 multiplier, max voltage was 1.2v

Aida64 temps as high as 71c on individual cores.
Gpu z stress test 63c

These seem far from dangerous but higher than what I was expecting. Doesn't seem much room for overclocking (although admittedly I've already set all cores to 45.)
Cheers
 
You might just be using more voltage than you need, try and lowering down a bit if your happy at 4.5 otherwise try a higher frequency and just keep an eye on the temps.
 
Voltage is set to auto and yes I could try that but really don't know much about 'lake' oc, give me Haswell any day!

For reference my old 4790k used to give similar temps at 4.6 and using a water cooler
 
I'm putting my money on the Asrock board being a bit too enthusiastic with it's auto voltage settings. I've had a few Asrock boards over the years (last was the Z97 Extreme4) and they've never let me down when it comes to stability/reliability... BUT... They're not that great when it comes to voltages or even sensor readings from my experience. This could have very well changed in the last couple of years though.

Thanks, it does seem strange that the bios reads 55-56c constantly even seconds after a cold boot.

I had the same things with my Asrock Z170 / 7700k - just disregard the temps in the BIOS and use temp monitoring tools in the OS.

My Asus Z270 Code reports temps accurately in the BIOS.
 
Ive noticed my cpu temps are always higher in the bios then in windows.. I guess the cpu is not optimised in the bios and all cores are running at full speed.
 
So I reduced it to 1.15v and got 10c less but I also think it dropped the multiplier to 42 so I'll have more of a play tomorrow now.
 
For reference, my i7 7700K is stable stock speed at 1.17vcore set in BIOS. HWiNFO reports a vcore range of 1.08 to 1.164 depending on load and cpu package temp maxes out a 61 degrees C after 7 hours of x264 16thread stress testing.

Motherboard is Gigabyte Gaming 7 Z170.

I run a custom loop and am pretty disappointed with the temps. Will be delidding the next week or two.

Hope that helps.

50+c at uefi level is high, check it's mounted correctly before taking the CPU apart again.

Thanks I did that initially and it could have been tighter, even after tightening it's still high in bios but low in windows so I suspect it's a bios bug.

It's now running 45 multiplier @1.14 and temps of low 60's under stress, although aida64 and cpu-z rather than something more hardcore
 
My 6700k was quite hot to start with, but temps seemed to drop after a few weeks. I tried reseating the CPU block, even got a new CPU block, to no avail, then it sorted itself out. I have a feeling it was the internal paste as opposed to the stuff I put on.

It's probably the inch or so of tim intel squeeze in with all that black gunk raising up the ihs!
 
Had a very quick and dirty play and got 5.1ghz at 1.4v temps weren't too bad (considering) 85c but If I were to run it at 5ghz it would need a delid.
 
I daren't go near 1.4v with mine, stress tests on a 4.9GHz overclock at 1.33v has the cores spiking at 97 degrees, on a Corsair H115i. (80 on average though with no throttling)

I have a feeling it may be the almost completely dried out Isopropyl wipes I used to remove the old thermal paste when I installed it, so I'm going to have another crack at it with some proper thermal paste remover and see if that improves things, if not I'll live with it.

I doubt it mate they just seem to run very hot. Hotter than my old Devils canyon chip by some margin!
