    So I finally took the opportunity of upgrading 32gb ram to repaste/LM the hotty i7 8750h with full rtx 2080.
    The boy was rasing up to 95°C in COD MW and around 80°C for the GPU even with a good -130mV undervolt.

    TBH the repasting was a pain for me especially the cleaning, I took my time (3h almost) to clean and repaste everything, quite a mess when I took a look at all the toothpaste to remove. I applied isolant lacquer on the sensitive parts too.

    I am disappointed by the results though. Like 8-9C colder on the CPU and almost nothing on the GPU. Did I apply to few LM? I dropped and spread a lot a very tiny drop on each DIE and copper heatsink.
    Contact on the DIEs seems good too.
    I must say I'm used to apply thermal paste but not much LM, that is my third laptop repasted with it. Quite lazy to redo the whole thing but if that's worth it...
    I know I applied thermal paste on useless parts :p

    That's an excellent job already and if you got 8~9 degrees colder that's a big profit. Well done. :)

    ok thanks, I was always reading results like 15 even 20 sometimes with LM but maybe not with this configuration though...

    8-9 degrees under load is very good

    Well, have you taken into account the fan speed? It is likely that your fan speed is lower now than it was before if you are using auto. You should only really compare numbers when using coolerbooster or something that gives a good constant fan speed. If left on auto/stock, temperature targets are what controls how warm things get and they tend to be set high given the paste manufacturers use. When I repasted the gpu on my gt75, it still ran at 80C+ but the fan no longer sounded like a jet. After limiting the voltage and OCing in msi afterburner it came down to like 72C. That was in the summer (no AC).

    Undervolt it as well... that will give you a further temperature drop..

    I guess you didnt read the 1st post when he said -.130mv undervolt.
