[SOLVED] I7-12700k running hot ?

[Daniel_Adams]

Hi guys first time post here so bare with me.
First illl start with Specs
CPU - i7-12700k
MBO - MAG Z690 Tomahawk Wifi DDR4
Cooler - Noctua NH-D15 (duel fan)
GPU - 4070ti
Case - Corsair 4000d Airflow
Fan Config is
3 intake at front
2 exhaust top
1 exhaust back

Now most of the specs are out of the way. I built this PC probably about 9 months ago with the addition of the 4070ti about a week ago, temps were never great with the CPU but they weren't getting this hot. I understand the GPU does take up alot of realestate in the case but im hitting 99c after 2-3mins in Cinebench r23 (HWMonitor Temps)
So Ambient is sitting at around 24c and my idle temp is sitting at about 30c while typing this. When I jump into Cinebench R23 temps jump upto 87c and climb to ~95c. I hit 99c the other day when ambient was a bit hotter. Bare in mind it is Summer in Australia. Ill attach some screenshots of HWMonitor while Cinebench is running maybe you guys will have a better understanding of what is going on. One more thing. When playing games like Warzone 2.0 or Horizon 5 my temps sit around that 80c mark which isnt as bad but still sitting on the hotter side.

Couple things I have tried are:
Sitting Fan infront of PC which didn't change temps.
Changed the default Cooler in bios to boxed cooler which changes wattage to 244 rather than 4090w water cooled?!
Tried Disabling Enhanced Turbo in bios.
these things didn't really change much, maybe a degree or 2

I would appreciate any advice you guys have to offer.
Cheers.

So just realized I don't know how to attach images from my desktop to this Forum. if someone has an idea, please let me know

I'm talking 1.4v VID the vcores max out at about 1.2. And yeah I probaly could go lower but might push my luck with a bit of a clock boost. I did notice my clock speeds are hitting 4.9ghz now for whatever reason, must be an auto overclock setting in my mobo still

Ok VID is the voltage requested by the CPU not the actual voltage supplied by the board. 1.2v vcore sounds pretty good. When you say the CPU is hitting 4.9Ghz, do you mean 4.9Ghz on all cores?

 

[Nighthawk117]

So I just read online that VID or 1.4v is what that core is requesting but realistically the vcore at 1.2v is what it is being supplied? So I don't really need to worry about the VID voltage??

What you've done won't affect the VID. It's the vcore that's the real voltage, that's the one you need to worry about.

Ok sweet glad the VID / Vcore is looking good. Now I believe the 8 performance cores are maxing out at 4888mhz in hwmonitor after a couple hours of games that is (had hw monitor opened in the back ground.) And encores 3791mhz

When I get up in the morning (10:30pm here) I'll do a quick cinebench run and post the HWMonitor stats so you can have a clear picture of what's going on. I really appreciate the help @Nighthawk117. You have been a life saver.

Every core may hit 4.9Ghz at some point but I wouldn't expect all of them to run at 4.9Ghz at the same time.

Uncore seems higher than normal, I think it should be 3.6Ghz.

Your welcome, I went through the same experience, Intel chips are like little nuclear reactors out of the box. I think you could probably push the undervolt a little higher than what you have actually but that's up to you. You can also undervolt the E cores as well but I don't have any of those so not sure what the settings look like.

You get away with so much by just undervolting these CPUs... for example, a 110mV offset is enough that the 12700K can be cooled quite well by a BeQuiet! Pure Rock 2 while Game Boost/Creator Genie is active and the CPU thus overclocked by 100MHz. Power consumption about 150W.

@Nighthawk117 pretty sure they mean e-cores, not uncore 😉
And the e-cores get undervolted with the rest of the cores iirc, no need to change anything for them individually.

Yes well worth doing, seems more easy to do on the recent chips. Yes of course they probably meant E cores.

Just did a Cinebench Run with the same -0.08v these are my stats in HWMonitor taken during Pass 5 @Nighthawk117

All stats are running A lot better. You can see performance cores maxing out at 4.9Ghz and 2 of them are hitting 5.0ghz
