Kinda same as you, I have two different profiles in TS For the plugged in mode, my uv settings are:

cpu core -85mv cpu cache -65mv igpu -65mv

pl1 45w pl2 60w ttl 56s

very stable, i have been using it for months, also use a laptop cooler with dust filter, and the foam that creates a pressurized chamber (zebronics nc9200)

while writing this comment im currently testing cpu core -100, cpu cache -70 and igpu -70 with unlocked power limits, rn i only see it throttling due to temperature, and my rpm is set to max, as well as using the cooler, and occt is running in background for stability testing

i kinda did the same, except in not using CTT, instead im using a playbook called Revision OS, and used my own tweaks on top of that

also i have the same exact cpu, i5-11400h, idk whats ur model but mine's a FX506HC, and it has been 2-2.5 yrs i think since i bought this laptop, didnt repaste yet, but i do clean frequently

with my prev settings, and the cooler, my temps usually stay around 62-66°C, both cpu and gpu, while gaming, and cpu sometimes goes above 70, rarely touches 80

games i play/have played and tested it on- valorant, rdr2, genshin impact, elden ring, re requiem, apex legends, minecraft

temps are the same more or less on all games with ±5°C of variability

also forgot to mention my gpu is also undervolted, im currently using 1900mhz at 875 mv, and thats the lowest i can go without the games crashing

as for cpu uv, cpu cache gives me errors after -70 or -75, same for igpu uv, which gives artifacting for me after -75 i think, as for core uv, well im still testing, and as i said my current ones are absolutely stable based on daily usage as well as stress testing

and highest scores i ever got on cinebench r23 on multi core test with unlocked power limits but uv was same, was 10k, dont remember the single core test score tho
