14700k getting too hot?

[Vimes]

By default my Gigabyte motherboard would have both power limits set to unlimited. I reduced those to 253w, the max for the 14700k.
Also I added an 0.07v negative offset to the vcore.
The cores seem to boost to where they are needed and the 420mm AIO seems fine.

The power limits should be set at the CPU's maximum by default, but it seems that often does not happen.

Then again I am not typically using an all core sustained full load on the CPU for extended periods.

The max vcore on that screen would suggest that you are at defaults.

Mad to think a **700 series chip can put a 360 AIO cooler to the sword.

In your screen shot you've got fans (aio I presume) only hitting 800-900 RPM. Have you got the fan all in the right mobo headers? Have you any fan curve set up in the BIOS? Do you have the fan headers in a splitter cable or how are they plugged into the mobo?

1.38V in the CPU is quite high too, might be the boosting doing that though.

Ive now got the aio fans and exhaust set to hit full speed when cpu temp gets to 60c. The temperature is now under control, the noise is no joke though.

I looked into undervolting it but ive got a b760 and apparently b boards aren't meant to be undervolted and can only be done by changing back to the old microde. Ive read that it can cause instability so I think ill put up with the noise from the fans for now as Im a pc newb and dont want to cause any issues that I cant fix.

Interesting about the "B" type boards. A reason for me to be wary of other types, from what I would call more enthusiast ones.
Sad really, noting the vcore voltage that seems to be used by default.
Even the offset I noted does seem to make a difference.

Does that also apply to the power limits..? I assume they could be unlimited. Again that made a difference.

If I would run, just to check, R23 I now see my CPU is limited due to those power limits and not due to thermal loading. That does make for easier cooling. Not easy, at times, but easier.....

is it keeping the 5.6Ghz boost clock when its hitting 90c ? If temp are an issue you can set all cores lower to maybe 5.4ghz and then lower the vcore

@jabski the OP replied just above my post that his board can't undervolt easily the CPU

ah yeah sorry. I havent used b760. I wasnt aware they were so locked down

Well Ive just had a go at undervolting and overclocking my 7800 xt. It seems to have gone quite well as Ive got a descent score but was wondering if cpu data is ok.

I Used timespy and during the cpu test I got these numbers:

CPU VCORE 1.476V
Package 92C
Package 266.84W
P-Cores 5487-5586MHz
E-Cores 4290MHz

Im not sure how intensive the timespy cpu test is but Im guessing that the voltage is going too high?

 

[Vimes]

I don't know about that test but running R23 and I see 253w, set limit in bios, being the governing factor and 1.275v as the max vcore attained.

Yeah, but, it depends because these CPUs high volts for the single core boost, so it's not necessarily that bad.

Ive just run cinebench for the first time. The temperature briefly spiked to 96C but that was only for a second or two.

The p-cores only briefly rose to what the max shows. They spent most of the time at about 5100-5200MHz. Is that normal? Should they not be at 5500-5600MHz?

if your clock clocks were at 5.5-5.6ghz your temps would likley be around the 100c mark, voltages would have to be increased a fair bit to get those kind of clocks, out of box settings would allow this but at the cost of very high temps.

There's a few things you might want to be aware of: CPU benchmarks aren't always @ 100% workload all the time and if they use AVX the turbo boost can be lower, depending on the offset.

Ok so in regard to my temperatures (95C timespy, 96C cinebench), do you guys think that I need to pursue undervolting the cpu? My motherboard doesnt support it without changing the microde which can cause a lot of problems in some cases, so Im not sure if its worth trying?

What are your temps in the kind of things that you do normally with the PC?

Its a bit cooler now that the cpu fans and exhaust are set to hit full speed when cpu gets to 60C. So gaming is in the 50-70’s, video processing up to 85C. Very noisy though.

Did you set the power limits and check the automatic overclocks in the video I linked?

 

[Clarence Boddicker]

I didnt set power limits as I was concerned about loss in performance. I did look into disabling the automatic overclocks but my bios is different to the one in the video, he did say what to change in the gigabyte bios but mine doesnt have the options that he mentioned so I couldnt identify the right ones.

 

[Vimes]

You would be setting the max power limits to the CPU set by Intel.
As you would struggle to reduce the vcore voltage, that seemed high, it could be your only limiting option.
It is these types of motherboards that are having unlimited power limits by default that are the issue.

What makes it worse is that they dont support undervolting, which would help solve the problem that they've created.

You do lose some performance, but it really needs to be done to get the power usage and temperatures under control. Most of these CPUs are very effective when they're power limited, even 125 watts loses very little performance in the majority of apps.

You could take some pictures.
