    Yeah definitely not keen to take it out in case I screw something up. I'll send it back to Ken and send him this thread URL for reference so he can understand my point of view as well. Hopefully he can take special care when applying the next paste (especially if it's liquid metal). He's been great to deal with, so I definitely don't have any complaints.

    Not sure if they made a mistake with the paste or screwing the heatsink back on causing uneven pressure, but I have high hopes that everything will be corrected. Thanks again for your time in replying to the thread.

    I'll make sure to update the thread when I get the laptop back with some more tests/temps.

    underclock and undervolt? throttlestop is your friend.

    Yes, I have tried both as mentioned in the thread. All of the temps/screenshots that are on the 2nd page of this thread shows that it's been undervolted, but still seeing temps that are hotter than normal (and cores at widely different temps). I went ahead and sent the laptop back today to get a repaste with liquid metal.

    liquid metal will help little. your laptop is overheating because either poor contact or just too thin of a laptop to have an useful heatsink, or fan not spinning enough? especially if that heatsink might be shared with GPU if it has a discrete one.

    if your heatsink is too small, then only way to do is undervolt, and if thats still no good then you need to underclock ontop of that, or lower your PL1/2 value in throttlestop.

    Thank you for your input. It seems that liquid metal will help, the overall consensus in this thread seems like it would help a lot more than my current paste. Other people that have used LM on the previous generation laptop seem to have a lot of success with it also. Even the re-seller (GenTechPC) said the paste that I chose was a bad option for the laptop - which warrants a re-paste in and of itself.

    You can see an example of the temps someone is getting with liquid metal here ( posted by @Felix_Argyle on the second page of this thread: https://www.reddit.com/r/MSILaptops..._stealth_thin_result_of_repaste_and_applying/ )

    I also posted my fan curve in this thread (again, 2nd page) and my fan is running at high values when the temps are high.

    I will need to undervolt with liquid metal as well to achieve good temps, but I'm certainly willing to do that. Undervolting and still seeing >90C temps is not so great in my opinion and could be improved. While the heatsink may not be the best on the gs65, most people don't seem to have 8-10C differences in their cores under load and do seem to have better temps than what I am seeing.

    That's why I decided to send it back to see what the liquid metal application will do. Hopefully it will improve temps. Maybe, maybe not - we will see when I get it back. I will be testing and posting the results here for sure.

    Here is another video for you, repasting GS65 with liquid metal. I know that you don't want to do it yourself but you should read the video description. It says that the person who did it saw a 24C drop in AIDA stress test after repaste. The CPU is a previous gen 8750h but you should be seeing a similar drop if liquid metal is applied properly.

    Yup, that's pretty much the exact reason why I didn't want to open it up myself haha. The shipping there took a week by ground and I requested 2nd day air back to me. Ken said laptop is ready to ship so I'll update this thread again once it's here and I run some tests. Kinda sucks that just the shipping has cost another $90 and it's been over a month now since I ordered the laptop with only using it for a couple of days.

    He said when the tech tested it, it was "3DMark CPU around 90~92 max". Hoping with an undervolt it will be considerably better than that, and also hoping for more even core temps.

    Got the laptop back just a few hours ago. I'd say that I'm definitely pleased with the reduction in temps. I can actually put my hands against the wrist rest while running AIDA and it doesn't feel like my hands are burning. I haven't tried gaming on it yet (have a bunch of work to catch up on now), but overall I'd say that the LM reduced temps by quite a considerable amount.

    @custom90gt and @Felix_Argyle I very much appreciate all the input you gave.

    My idle temps are still running about the same as they were at - about 37-39C idle.
    My full load temps are running quite a lot lower than before - averaging about 79C under load.
    The CPU cores are not seeing such huge differences between them in temps - they're all about the same on average.

    You can see the new stress test pic here with AIDA 64 and HWMonitor: https://i.imgur.com/pllZY1s.png

    Edit: Didn't realize my undervolt was cleared, but my CPU max was still set to 99% in the battery settings. With the undervolt it was reaching about 1-2C cooler than the temps above.

    Much appreciated with all the input. I'm a little disappointed with all the extra wait time and costs that were involved when I feel like this was GenTechPC's fault (giving me a paste that wasn't recommended and the CPU core temps being so far off each other).

    I will say that Ken@GenTechPC is pretty responsive to e-mails but his e-mails are usually short and not always answering the questions you ask, so you have to follow up a few times. In the future I'd probably just go with a slightly more "respected" reseller. The shipping costs ended up being the same as if I would have gone to HiDEvolution or similar which seems to have better reviews overall.
