    Well, it seems like temperatures depend heavily on ambient/room temperature. With now 26*C in my room, I get similar results, although the CPU Temperatures of 94/95*C is just a short maximum, as the fans take a while to kick in. Average CPU Temperature is around 88/89*C when playing BF V (on my unit with the 2080 max-q).
    Especially since the fans cant go any faster, rising ambient temperatures mean rising component temperatures.
    I also encountered GPU throttling in this warm environment, but I dont want to repaste the laptop just yet. I would prefer to wait until it gets colder in germany, and compare the temperatures then (maybe september/october) to my initial results so we can see, how well the thermal paste lasts.
    Overall, "you get what you pay for" seems to be true here again - prices on the y740 are fair compared to many laptops from competitors.
    The RTX 2060 / 1660TI seem to be the best value right now - especially the latter really offers great performance for the price.

    That is my room temperature during the summer, can you please tell me what are the max-CPU and max-GPU temps you are getting? You have 9750H with 2080 MAQ-Q? Also do you have 15 inch or 17 inch?

    Thanks.

    No I have the 8750H, but here a Screenshot of GPU-Z and HW Monitor during a 25min BF V Rush.

    This was done with 28*C room temperature though.
    The CPU average temperature is okay, but I dont really like seeing the GPU Temperature so high...

    This is interesting as all the previous youtube reviews and user reviews all said the y740 had amazing cooling (likely due to the paste that Lenovo uses). So I wonder why this is an issue now.

    Y740 9750h with 2060 is using higher TDP 90w 2060 instead of 80w (like the 8750h version) which results in much higher temps.

    From what I've seen, people with thermal issues have i7-8750H and bios 1.09 combo. Am I wrong? People with i7-9750h (at least on reddit) claim that their thermals are still good... Am I missing something?

    I've ordered 17 inch model... Any issues I should be aware of? Thanks.

    I have the 9750h version 15-inch with RTX 2060, Anything I can do to help add to the discussion? I have been playing "Rust" on my laptop and every time I play the game the fans come on not super loud but noticeable after I exit the fans gradually slow down then I think they are super low or off because i can't hear them after.

    Wanted to add I'm not on the latest firmware as I read the posts here first.

    I haven't had any thermal issues on 1.09, only difference is I can't force the fans to stay at max but that's not a big deal for me 95% of the time.
    That said, I'm also undervolting which helps considerably (probably a 10-15 degree difference), I usually don't see max temps above mid 70s unless I'm running benchmarks or something.

    Unless you mean the 9750 and 1.09 combo is bad, and 8750 is still good, in which case, can't help you there :D

    Important SKU Information
    Since there's a fair bit of confusion on this, here's a post with all the info on the refresh vs old 8750h units.

    9750h units (IRH/IRHg)
    • Latest BIOS is v1.06 (as of writing)
    • Current BIOS yields best thermal performance
    • RTX 2060 is 90W variant (15% better than 1660ti)
    • 2060 unit is about 10-12% faster than the 8750h equivelant
    • Processor limits at 50W due to RTX 2060 pulling 90W. Could push to 55 in less GPU intensive titles, or power limiting GPU back down to 80w.
    8750h units (ICH/ICHg)
    • Latest bios is v1.09 (as of writing)
    • Current bios results in poor thermal performance
    • Last known good bios is v1.08
    • RTX 2060 is 80W variant (within margin of error of 1660ti (2-3%), same wattage)
    • Processor limits at 55W with a little bit of room for more.
