    155mV undervolt + custom fan curve + Coolermaster Mastergel Maker Nano (kinda like Phobya nanogrease, a bit worse maybe but I couldn't get phobya easily where I live).

    GPU at 90C, CPU hovering around 84C, pinned at 3.9GHz while gaming.

    I got it more under control now. This paste is very viscous and I applied a thick layer after warming up the paste a bit. It seems to be a nice choice.
    GPU temps still worry me a bit. Core clock is never below 1750MHz so it isn't throttling that much. Maybe It has to do with the thermal pad thickness, gotta check it again.

    On max fans GPU temp doesn't improve, but it gets closer to 1950MHz. My current custom fan curve is still pretty far from max fans.

    The MXM module is also quite movable. You can push it down, away from the heatsink with little effort. May but a little rubber spacer behind it to improve contact.

    So glad I found this site. I had the GT62VR and it ran around 72c full load, so when bought the GT63, I was expecting higher thermals, not 90c in the first 3 minutes of stress testing. I actually had it RMA because I called MSI and they told me it shouldn't get that hot. After getting it returned to me, the temps didn't change. I complained and got an extra year warrantee on it, so that was cool. Anyways, I used Innovation Cooling Graphite Thermal Pad – Alternative to Thermal Paste/Grease (30 X 30mm) and it greatly slowed down the the time it took to get to 90c, but still hit 90c. I removed the bottom case and then ran stress tests again, and it held 85c (GPU) and 77c (cpu) for over 15 minutes. This case has serious airflow issues which is expected with a laptop. I'm think I'm going to buy a used GT62vr bottom cover, since it fits perfectly and is cheap, and do some modding by cutting some holes where the fans are and see if I can improve air flow, since gaming without a bottom cover is out of the question.

    HID Evolution does a great mod in the GT75 series. Looks like this

    I agree, the bottom cover doesn't make much sense. The fans are literally a few milimeters away from a solid plastic wall.
    Maybe it forces air across other components on the motherboard and that ain't so bad. But they still struggle for air.

    In the GT63 lifting the rear of the laptop a few cms, undervolting the CPU and raising the speed of the fan curve in dragon center make a world of difference.

    Let me know if you find a compatible bottom cover anywhere. I was looking for one but I only found quite pricey offers.

    I picked up a used GT62VR bottom case cover on ebay for $33. I see a few new ones on ebay for $89-95. I should be getting the cover this weekend, and I will start cutting some holes. I might try just drilling some holes with a screw first to see if that will be enough. If that is not enough air, I will cut out large holes, and glue some mesh over the holes to keep large things from getting in the fan.

    I think another reason for the fan placement was noise. With the cover off, the fans are very loud with cooler blast on. I'm wondering if there is a way to kick up the fan RPM. I tried to use afterburner, and other tools including dragon center, but I guess I am not able to change it within windows. I wonder if there is a hidden bios setting. I am not really worried about burning out the fan, since new fans are cheap online anyways ($25-35 each).

    I wonder if there are any hardware changes I can make. I am also going to see if I can some how mount another fan in there somewhere, but I am am not sure how I could power it.

    Is your heatsink making good contact with the cpu die?

    Silent Option doesn't let you change the fan speed?

    Last resort, ask Svet and he will either mod your EC firmware or send you the EC editor and you can set custom curves, I have made custom curves on my GT72 and now I never need to put the fans on max, bumped the idle speed a bit and made the ramp more proportional to the temp and it stays at 65ºC on the GPU after hours of gaming, that and using Kyronaut.

    Looking forward to your mods on the bottom case...i have the GT63 Titan with the 1080 and had HIDevolution do a Liquid Metal repaste on it and a BIOS applied -50 undervolt and it seems to have really helped the temps compared to what others I am seeing (high 70's, low 80's max after some stress testing on my lappy). Always looking to drop the temps more though. Can you post photos as well when you are done Dr. Frankensteining the bottom?

    I will do. How do i get hold of Svet about modded SC firmware or how to unlock the bios? I think I am going to try to get a small fan in there somewhere just because I can. I am trying to figure out how to power it right now.

    Go over to the MSI forums and post in the BIOS Mod requests, he will then PM you back.

    Send him a private message on the official MSI forums https://forum-en.msi.com

    You will have to donate for his work but his work is top tier. He has helped me several times and even saved my Intel ME firmware from me bricking it by messing with an option in the unlocked Bios I had no business messing with (Please don't disable the Intel ME . just don't).

    BTW the only thing useful that you would care about in the unlocked Bios is the overclocking performance menu (where you can set adaptive or static voltages and undervolt easily, and set memory DDR4 voltages--GT75VR allows this, GT73VR's bios doesn't have that compiled), CPU VR settings, where you can set the internal IA AC DC loadlines to 1 to stop automatic MSI overvolting (Never ever go anywhere near the upper values, ever); this happens because MSI uses a preinstalled "Loadline Calibration" that the user has no access to, which somehow affects CPU VID (long story; in desktops, Loadline Calibration affects the CPU VCORE circuit, not the VID request), changing IMON SLOPE to less than 100 and IMON OFFSET to a negative value (to make the CPU report its using less power to bypass TDP restrictions), and changing a few other things of questionable importance (FCLK to 1 ghz rather than 800 mhz, or unlocking "CFG Lock" which lets Throttlestop change the C-states in windows). Nothing else is really that important unless you're using an external monitor (there's an option to allow the Bios to output to the external monitor while in the Bios. Busted on the GT73VR--doesn't work with the Nvidia GPU but does work with the iGPU).

    MSI GT73VR users needed to unlock the bios to set the Peg root port 1 from auto to enabled, to bypass a silly bug which caused a black screen when switching from dGPU->iGPU->dGPU under some bizarre circumstances (zero drawbacks to doing this).

    Thanks for the useful information. I will send him a message later tonight. I was going to post a of my modding experiment, but not sure how. I just cut the holes to test what temps I'm getting. I'm hitting 87c and 80c after 15 minutes of stress testing.
