    Laptop: Thinkpad E470

    Specs:
    i7 7500u (dual core 3.5GHz)
    940MX 2GB DDR3
    8GB DDR4 SODIMM single channel


    So my laptop gets hot, really hot. Like 97 degrees on GPU and like 85 degrees on GPU when gaming. I was wondering how to tackle this problem

    I tried undervolting, still hits 97 degrees. Performance in games is crippled, from 120FPS average to below 30 with huge drops

    I tried manual fan control, still hits 97 degrees after a while

    This is what I am working with. CPU is up top, GPU is the small square

    I will try cleaning that fan and see if it helps

    I was thinking a repaste is now in order. I am stuck between liquid metal, normal thermal paste, or a graphite pad.

    I am a student so this laptop is going to get thrown around a lot, I’m not too sure if liquid metal would be a reliable solution.

    At the same time, I’m not sure even a high end thermal paste like kryonaut would help. Both undervolting and cranking the fans haven’t even made a dent in temps, im not sure a paste has the punch I need

    I’m also worried the paste or liquid metal will get messed up when I go outside. Walking through -25 degree weather with wind means that the laptop gets really cool and pastes might get hardened and softened. That’s why I was also considering a graphite pad

    I really can’t figure this out, so I thought I might have a better chance if I ask around.

    Any help would be appreciated

    Hello,
    From your description, I would try changing thermal paste, and making sure it is doing a good contact on CPU and GPU before anything.

    Any good thermal paste will work unless you have defective heatsink. I used CoolerMaster Mastergel maker nano, Gelid GC Extreme is also a good paste.

    I'd recommend Thermal Grizzly Kryonaut, it's the best non-conductive thermal paste in my opinion. Their Carbonaut pad should be a good alternative. How long do you typically walk in -25?

    I usually stroll around half an hour or so when it's cold. I'm worried that that low temp will make liquid metals and most pastes dry/harden and that would really impact performance. I know carbon pads don't get affected by the cold
