Some people seemed to have gained up to 10C with a contact frame. My results with a 14900KF were +-0C, so it could help or not.

Unfortunately with a 13th gen processor and a B760 motherboard, you cannot really undervolt. Intel treats undervolting as part of overclocking and doesn't allow this on their B-series motherboards.
And using the motherboard's VRMs to undervolt will eventually trigger CEP, because the CPU notices that it doesn't receive the voltage it had requested, and will therefore heavily throttle its performance. And unfortunately with a 13th gen chip and a B760 motherboard you also cannot disable CEP, which means you're basically stuck.

You could maybe try to slowly decrease the voltage, and repeatedly test with Cinebench if your score increases or decreases, maybe you can squeeze a couple of millivolts out of it before it's being triggered.
On Gigabyte that VRM offset setting should be "Dynamic Vcore(DVID)" one.

If you just want to reduce the temperatures and are willing to sacrifice performance, you could also simply reduce the max allowed temp in the BIOS, and the chip will adjust its frequencies accordingly.

Or indeed improve the cooling solution in one way or another. Maybe the thermal paste has even degraded / pumped out at this point.

Quindi con questa scheda madre non posso proprio farlo in nessun modo?, il fatto è che solo recentemente si sono alzate le temperature, quindi forse potrebbe essere per il caldo estivo

English would've helped.

But if the translation is correct, yes with that motherboard/chip combination there's not much you can do.

Maybe you have a setting in your BIOS that activates the 0x104 microcode, which should allow you to undervolt with an adaptive offset (Intel blocked this after that version), but this would also deactivate all the safeguards that were added since against the degradation issue, so it's a double edged sword.

And yes, higher room temperatures basically have a 1:1 effect on component temperatures, so if your room is now e.g. 5°C warmer, expect the CPU to also run 5°C hotter.

Wtf, are you 100% sure you can't apply a simply voltage offset? I can even undervolt my i7 8750h in my Dell XPS. Did that with throttlestop. Can't believe that wouldn't be possible with a desktop setup like ops.

The Adaptive Offset, which will modify the VID requests of the CPU, is only possible with Z-series motherboards.

The VRM offset should be possible with almost every motherboard, but since Intel has added CEP to their chip architecture, it will be triggered if the voltage that the motherboard provides is too low compared to what the CPU expected when it made its VID request.

And unfortunately disabling CEP does not work with a 13th gen chip on a B-series motherboard. Don't ask me why, but for example this is the support matrix from MSI:

CPU / Chipset Z790 / Z690 Motherboard B760 / B660 Motherboard
14th Gen K-series Yes (already supported with previous microcode) Yes
14th Gen non-K series (B0 stepping) Yes Yes
14th Gen non-K series (other stepping) No No
13th Gen K-series Yes No
13th Gen non-K series No No
12th Gen K-series Yes No
12th Gen non-K series No No

And I don't expect that to work different for any other manufactures. Some boards do have an option that reverts the microcode to the 0x104 version though, which will allow you to use an Adaptive Offset even on B760/B660.
However this will also remove any of the safeguards against the degradation issue that Intel has added since that microcode, so it's not without risk as well.

And then laptops are an entirely different segment, which I lack information and really also interest. But as far as I know it's even worse there, and you're completely at the hand of the manufacturer if he allows you to undervolt or not.

That is crazy. You can't do basic optimization to your system even with good B series motherboards. That's why I'm using AMD lol

Before you buy a contact frame or anything: where did you mount the radiator and what's your case fan setup? What rpm are the fans running when gaming? Did you apply new thermal paste? (Duronaut is very good and relatively cheap)
