Is there any good undervolting guide?

[Phazoner]

My 6700k is pretty hot, so I'm playing at default frequency (4Ghz) with an vCore offset of -0.150v, it really improved my temperatures but they can be much better. With an single fan 120mm AIO and FPS unlocked I'm getting around 80ºC in Battlefield V (nearly 100% usage) with an ambient temp arount 27ºC .

I am only changing the vCore offset because it's the only thing I know I can do (I found a extensive tutorial with Intel Extreme Tuning which only configures that :/). I think it could be better with a vCore modification, and I think y read something about undervolting cache memory too, but I really don't know what am I doing so I prefer to hear from the PROs.

Thanks in advance

You are better off looking at y0ur cooling solution. Better cooler and airflow is going to give you better rsults.

Also 80C at full load is within tolerance and specification. What are your temps at no load?

As you undervolt you also need to reduce frequency to maintain stability, the opposite of overclocking.

Do you really want reduced performance?

I substituted the MSI premounted aie cooler, which looks like a much bigger version of the Intel stock cooler, with an Silverstone TD02 SLIM AIO which is supposed to be the best cooling option for my ITX but I'm not really getting better results, which is weird.

I had some problems with the installation because the premounted PC has a fixed backplate which won't fit the AIO 3.5mm screws, so I mounted it with 3D printer components (2.5mm screws and nuts) and I really don't know how much pressure should I put. I read pressure should be just enough to avoid the cooler/pump to be able to be moved with my hand.

I also think I could have put too much thermal paste but according to some comparison tables too much thermal paste shouldn't really make a big difference.

too much paste is a bad thing, it does reduce cooling efficiency.

I am concerned that the motherboard back plate does not fit your screws. I am surprised that you could not replace the back plate with the cooler specific one.
Back plates are not glued to the motherboard (normally)

Turns out something happened at the middle of the installation and I just didnt tighten two screws from one side xDDDD my bad.

Thanks for your help
