I have the same exact laptop and I undervolted using Valour549's Ultimate ThrottleStop Guide

if you need help feel free to give me your discord

Go to techpowerup and find any post regarding 14900hx UV, it's common CPU in high tier laptops, so multiple people already asked the same question. There is everything you need there.

Use Throttlestop, there's guides on Youtube. Undervolting is specific to the laptop so only you can find out how low you can go by testing it.

What i write on other thread:

It is my same laptop! Congrats!

Download vantage from ms store and from there, download/update all Lenovo legion apps. Among those apps uninstall tobii; run once x-rite to download your legion screen color profiles and then uninstall it (you can manage your color profiles from windows screen settings so x-rite became just bloat). In vantage set batery on conservative mode (it will stop charge at 80% to lenght your batery life)

Vantage alternatives: vantage is lenovo legion app that manage all your laptop extra features (rgb, gpu selector, power modes, overclock, legion app updates, warranty plans. Etc) it is a good app but it has a lot of telemetry and run a lot of istances on the backround. It is advice to use "Lenovo legion toolkit". It is a comunty managed app that has less bloat and can do extra features vs vantage. You can download it from their page on git-hub and follow the easy steps to install. You do not need to unistall vantage, llt (lenovo legion toolkit) will disable vantage at its first run

Limit the power of your Cpu. It can get really hot reaching 100+ °C. You can do that by setting a costum energy plan on vantage/llt limiting the temps and power, but it will cost some minor performances. If you want to gain better temps with 0 performance loss you should also Undervolt. I used uxtu version 2.2.5 to undervolt (other versions didnt worked for me) loock on you tube how uxtu works.

What i did:(DISCLAIRMER! It may dont work for you cause silicon lotery!) creating a costum preset: APU temp tuning-> temp limit 88°c, skin temp lim 45°c;; Amd curve optimizer-> All core offset -20 (this last parameter is the undevolt -5 ≈ -25mV. It is sugest to start fron -10 and go down every 10.. -20 seems a safe space for most users but some luky guy can go down to -50);; name your preset and save. Every time you boot your pc you must manually select the preset!!;; i sugest you to lock a guide on yt how to use uxtu to better understanding my last paragraph XD

Edit: minor grammar errors

For a quick fix limit the cpu TDP or temperature on vantage. Else find a good undervolting guide.

Get a laptop stand if you don't have one or if you are not keeping the rear end of the laptop lifted.

I'm pretty sure performance mode will heat the CPU even more than usual especially if you don't undervolt. I run mine on normal mode and when I do switch to performance, the temps go up by at least 10 degrees.

Undervolt it bro this is common issue in intel hx chips that's why normal user should ignore it like plague Undervolt guide is present in youtube

why is your hwinfo very colorful.

why is it glowing in green and blue?

You can't undervolt AMD.

not possible on amd

Don't. Just don't. It's not worth it. Your laptop has great cooling. It won't "prolong the laptop's life". Just enjoy it as it is

GPU Undervolting here - https://youtu.be/rV0tWKLAprg

its not possibly to UV CPU but GPU can be UV'd there is this comprehensive guide i found on this server. It is like a guide for noobs :)

It would definitely help bring down temps by a fair amount. I made this handy guide on how to unlock undervolting on the newest lenovo laptops (and latest BIOS versions for older ones).

Undervolting is not something you need to do. You can try to undervolt your cpu and maybe get small power and temperature benefits but if this works or not and how hard you can push it is entirely dependent on every individual cpu

Undervolting is so good to do.

did you figure out how to undervolt?

its not unusual for the 14900hx to be able to undervolt -150mv or more. Your temps likely wont decrease much under load but the performance will due to being able to sustain boost clocks longer. In my opinion you should be undervolting this cpu as it seems to be overvolted stock. If anything it should improve the lifespan of your device as you are throwing less voltage at it. Here are my r23 scores with a heavy but stable undervolt.

Unless your CPU temps are around the 90s and your GPU temps being 80+, I personally wouldn’t fret too much about undervolting. The best thing you could probably do is make sure to prop up your laptop, so that more airflow can get underneath, along with regular maintenance. AFAIK, instability issues seem to affect only 6 gen legion models, due to the weak solder. Your laptpp should be fine since it’s a gen 9, but my suggestions for cooling still remain in place.

Mine is stable and only runs at 85c during gaming without undervolting.

1. Here is a guide on how to undervolt https://youtu.be/Q2QLCtUc804

If it doesn't work (in FIVR the offset that is on the top right is still at 0 and not applying what you are doing) that means undervolting is disabled in the Bios.

2. This is a guide on how to enable it https://www.reddit.com/r/Lenovo/comments/id0457/guide_to_reenable_undervolting_after_latest_bios/?utm_source=share&utm_medium=web2x&context=3

After enabling it, you can go back to step one and try it.

*Also when you start to undervolt, do it on battery not with the power brick connected, cause it makes sure that the system will stay stable even with lower power.

You can dm me if you want further help. :)

12700H can't be undervolted unfortunately as it's a Intel 12 th gen H CPU.

The 12700H can't be undervolted.

Here's a neat trick to keep the temps low

Put your laptop on balanced mode and keep the battery settings on power saving. Really helps keeping the temps low.

I can undervolt with my gen 8 just fine. You just need to enable CPU OC and disable UV protection in BIOS. Then in Windows disable core isolation. You should use Throttlestop 9.6: https://www.techpowerup.com/download/techpowerup-throttlestop/.
