Hi,

my friend has a i9 14900k and is a little worried about high voltages. Just wondering if anyone has any tips. ( on lastest bios )

That's vid just what the cpu is requesting, what about the cpu voltage at the top showing 1.6v?

This, 1.6V is what's going to the CPU and that is high. Your friend will want to dig into the bios settings and fix that. How exactly depends on which model of motherboard.
 
Might be worth using HWiNFO and checking what vcore it says, and/or checking the configuration in the BIOS.

I was getting too high voltages with my 14700k. I updated to the latest bios and new microcode and found that my voltages were still too high even with the intel settings.

I’ve fixed it now by setting perfdrive to optimisation, voltage now doesn’t go above 1.4v. That’s with a gigabyte motherboard though.
 
First make sure you are on the latest bios for the motherboard. Then choose the deafault Intel profile. This should help, but post the results here.
The hwmonitor i linked in the first post above is after a bios update and on default profile. Below is the bios he used.

make sure he has the latest bios of course:
I believe MSI bios's (possibly not all i dont know)
have this kind of option:
index.php


as various guides etc are around, undervolting is also a common tweak with 14th gen.
but the simplest way is to limit max voltage with one setting. 1.4V would do the trick probably.
This option is in the latest BIOS with the 0x12B microcode update released two days ago for my MSI Pro z690-A DDR4 and I set mine to 1.4 though monitoring with HWiNFO mine never goes above around 1.189 before and after setting it to 1.4v
