Hello,
Your should get the laptop thermal putty / liquid metal changed. Temperatures will change over time as the liquid metal slowly moves off the CPU DIE.
Also, you made some claims about temperatures and liquid metal in another thread which in my view doesn't take into consideration the CPU model and Intel's Boost technology and fact that the CPU is attempting to reach the thermal limit by design.

These temperatures arent normal and if they say it they are most likely dummies and should not work at this place.
Normal temps are for example 85 degree in peak gaming without cooling pad in normal room. Liquid metal is poorly applied by assembly. While your cpu reaches 95 degree, it will limit its performance to the ground thats why u can get drops from 150fps to 60 and even lower. Especialy when they promote their cooling system as one of the best in laptops. Its propably good but with right application.
You should not get undervolting by external programs at brand new machines and even under warranty.
If someone asked you the following, what should an i9-14900HX run at in a G16 laptop with default settings? The above is your reply based on your CPU or something else?
Your statement on the liquid metal not applied correctly at the factory, what is the basis for this?
There is a lot of rubbish on the internet / youtube which is usually the result of mis-understanding by people who have no knowledge on the workings of thermal paste and how it changes over time when it undergoes thermal cycling. You will see that most of these videos are people opening their laptop looking at the liquid metal and stating it was done badly, no evidence provided just their opinion with no real logic.
It is not possible to determine if the liquid metal was incorrectly applied if the laptop has been used for a period of time and subject to transportation / travelling. The only way to know is to open the laptop at the point the heatsink was screwed down and directly in the factory. The reason for this is simple, the moment the laptop is used and undergoes thermal cycling, the process of parts expanding and contracting during use, the thermal paste will move.
The more thermal cycling that occurs / laptop used over time the worse this gets, the paste thins out on the CPU DIE. Also being liquid it's easier to move so the impact of this which is known as thermal paste pump out is more severe. If you used the laptop for many months then took it apart it will never look like a factory finish or how it was when directly applied from new, so be mindful of such comments as all I've seen are just people jumping to conclusions based on what they see after usage.
I have a G16 with the i9-14900HX, when new it was running hotter than I thought it should so I took it apart (only a few days of usage) and reapplied the liquid metal myself to make sure it was perfectly applied and running to the best of it's capabilities. Since that point in time I kept the laptop almost always horizontal, as in flat and not tilted sideways or carried sideways. It went away on holiday with me for 3 months, used in a hot country with no cooling pad and when I returned home / after 6 months I took it apart to check the thermal paste and redo a few other parts (VRM / MEM chips / Chipset).
I have carried out quite a bit of testing on my laptop to make comparisons of temperatures with liquid metal, cooling pads, normal thermal paste and messed around with voltages and boost ratios to get an idea of how the i9-14900HX operates during use and the type of load applied. I do this purely because I like to mess around and push the laptop to the limit of what is possible and share the knowledge.
If I were to say a default i9-14900HX with liquid metal applied correctly will easily run over 90 DegC and be capable of peaking to over 103 DegC depending on load, why do you feel this is not normal?
Because it is actually normal for that CPU (i9-14900HX) and there is a point that the cooling system is not the problem for the high temperature but the fact that it is attempting to boost all the way to 5.8GHz on 1 / 2 cores, the tiny core cannot dissipate the heat so it runs hot no matter what. (issue is linked to power density)
If Intel set the boost algorithm to operate within 100 DegC and allow for peaks over 100 DegC, the CPU will be capable of running itself to the limit all the time, and that's also by design not because of the cooler. There is a lot to be said about the CPU temperatures and how it operates depending on Boost and from a gaming perspective there is a point that thermal throttling is terrible. But again there are limits as nearly every single high end Intel gaming laptop will be hitting the limiters during use all the time if they are left on default settings. The only true accurate measurement is to monitor the frequencies as you play, if they are staying high and not dropping it generally implies your performance is not impacted as much.
There is no one for all temperature design, an 8 P-Core Intel CPU will always be hotter than a 6 P-Core Intel CPU and if the boost frequencies are 1GHz higher overall it's just going to get hotter quicker due to the power consumption.
Games also impact this, older games which generally focus on less cores / single core usage will see the CPU run hotter. You really should look into ThrottleStop and boost ratios because if your CPU is attempting to boost momentarily to 4.9GHz during gaming it's just causing unnecessary heat. It's not about the warranty, it's about optimising your gaming experience, if you have the means and ability to make it run better why not?
I'm not saying mask a problem, if the cooling needs servicing get it done but afterwards if you could make adjustments to make it run smoother and cooler, that's a good thing no matter what.
