    Glad to help. I came across this issue recently, so I gave it shot to see whether it might the same in your case.

    Hello guys - sorry to bump up an old post.

    Got a M6800 with Core i7-4900MQ (2.9Ghz, upto 3.9Ghz TurboBoost) in the office. Have just repasted it with Gelid GC3 (CPU, GPU). Pretty decent application I think.

    In the Dell diagnostics, it seems to still have the max temp of 96 degrees (normally around 70-80s when not stressing very heavily). I guess even new, with the 4900MQ - it can run hot. Would it be sensible to just disable the turboboost in the balanced energy mode (e.g. day to day), and use turboboost when the application really needs it? (e.g. max performance mode when needed).

    I've used the Shin Etsu thermal paste (or TIM - Thermal Interface Material as reviewers would like to call it) on the CPU (4940MX) and GPU (P5000) in my M6800. There are some improvements in the temperature department, but like you it wasn't that much of a difference but kept within specs.

    However, what I noticed was although the max temp was slightly lower than before the system was now able to efficiently dissipate the heat away. Thermal protection measures never kicked in when stressing the system and the cooling fans never went off like a jet engine.

    To me the TIM is doing its job. Unless you move on to liquid metal but that is something I will not touch with a ten foot pole.

    IMHO, there is no benefit in disabling turbo boost in balanced energy mode. The speed boost usually lasts just a for a short period and doesn't cause the temperature to spike to high levels. I'll leave the settings to default and let the system handle it.

    Thanks - very helpful. Left it as it is.

    Used Artic MX2 previously - wasn't convinced it was helpful (so decided to get the decent thermal, open the system once, might as well use quality). Think Gelid GC3 is reasonably good as I can go (Thermal Grizzly Kryonuat looks harder to apply) without LM - workstation with LM slightly frightens me / and tbh M6800 isn't a system you want to reopen if you can help it. .

    Impressive system you have there (especially the P5000 upgrade)

    I agree on that part where you said "tbh M6800 isn't a system you want to reopen if you can help it". The keyboard ribbon that connects to the motherboard and the other flimsy ribbons that connect the other bits to the motherboard are a hassle!

    Does anyone know what the manufacturer/thicknesses of the light green thermal pads are on both the cpu and the gpu? When I repasted my cpu the green pads were pretty hard and now my temps hit 97 on core 1 and 80 on core 4 under load so I think my cpu heat sink is skewed. I have repeated this twice with the same results using artic silver mx4 and the got same temps. Thanks in advance for your help.

    Finaly got myself together and upgraded my M6800 with AMD M6100 to a Clevo (1617) branded GTX 980m.
    Having a new 9184J-heatsink on order with the complete VRM-block in the same height but still a few weeks away i did a small mod on the original AMD-heatsink with the Dremel (just as http://forum.notebookreview.com/threads/m6800-owners-thread.736278/page-111#post-10746733).
    Using my old X-bracket from the M6100 (perfect match to the original Clevo except correct height and hole size).
    Bought a few different thermal-pads and thicknesses and made sure everything were in contact sinze the new 980m card will bring the heatsink a mm or so higher up than the old M6100 and put Arctic Cooling MX-2 on both the GPU and CPU.

    Then i searched and found https://premamod.wordpress.com/2017/08/15/j95-nvidia-inf/ with INF-files (Alienware 17 R1 (2014) *Optimus* 980M – 970M) that work well with a little adjustment. In the nvcvi.inf file supplied from premamod i had to add:

    [NVIDIA_Devices.NTamd64.10.0...14310]
    %NVIDIA_DEV.1617.15CD.1028% = Section046, PCI\VEN_10DE&DEV_1617&SUBSYS_15CD1028

    [NVIDIA_Devices.NTamd64.10.0]
    %NVIDIA_DEV.1617.15CD.1028% = Section045, PCI\VEN_10DE&DEV_1617&SUBSYS_15CD1028

    [Strings]
    NVIDIA_DEV.1617.15CD.1028 = "NVIDIA GeForce GTX 980M"

    Now the most recent drivers is working perfectly with Optimus and everything.

    Temperatures is topping 75c in games with 28c in the room.

    Very nice. Have you run any graphics benchmarks with it? I'm thinking of picking up a 980m or m5000m for mine.

    I have a 980m laying around after my recent upgrade to the P5000. The 980m is a better performer than the m5000m at games.

    Let me know if you are interested.

    Here you go, fresh from just now. All settings is stock and standard with the new 398.82 drivers, nothing tweaked or overclocked.
