Question i7 12700f - Low core temps, high VR VCC Temps

[Recks214]

Good day, I'm quite lost on this particular finding I found when stress testing my i7-12700f and I'm looking for help with a curiosity that I've noticed with my system.

Running on the following configuration:

My cooler is a deepcool ak620.
Case is a phanteks p360a
I live in a hot country, usual temps are 29-33c

Stress Test: Cinebench R23, I can easily hit 19xxx score if I only do one run

The problem: Unlike most others, my score quickly falls to 15xxx or 16xxx if I do a 10 minute run, evident throttling it seems.

From what I can see from HWInfo during the test. My VR VCC Temp hits 102c after a good amount of time running Cinebench R23. This in turn causes the VR VCC Power to drop to 32W and this seems to be the cause of the performance drops.

I've learned that if VRM temps and Core temps have a large difference for GPUs the thermal pads need changing, but for a CPU I'm not sure what to do - I'm looking for any suggestions/tips/leads that can help me keep consistent performance for my system.

You can locate the VR on the mobo and add a thermal pads/heat sink there and also make a case fan blow over it to keep it cool.
Is this a pre build system?! The manufacturer might have set it up like that because the system can't handle more.
Or if it is winter in your region as well they might have set it that low because summer will be much harder on the system.

Your 12700f should have a max power of 180w but it is locked to 130w with 150w max.

I set those locks myself hahaha - in the interest of keeping temps low.

But the VR on the mobo huh? I have pads to spare...I presume my next course of action is to ask Gigabyte for a spec sheet on where the VR is?

Just tell us the model or look up a review, usually they talk about the vr.
You can also tell yourself, they are several cubes in a row on two sides of the CPU, with a blow down cooler they get cooled by that but your cooler blows to the side so no air goes down there.

I'm running a B660M DS3H DDR4. - I'm sure I can find info on those somewhere

and this is the holy wisdom I was looking for, I'll find a way to get some pads down there then reinstall the cooler - thanks man.

Also uh, any good budget blow down coolers around?

Your cooler is much better.
If your case has at least one fan to suck air in and one to blow it out it should be enough to cool the vrm as well if it has a cooler on it.
Anyway you can try that first and see if you need to do anything more later.
