    So when I got my Dell G3 (9300H + 1650), the temps were pretty bad. Scoring ~1900 in Cinebench R20 because of thermal throttling.

    I ended up buying some Arctic MX-4 and re-pasting. It didn't seem to help at all. Temps were around the same, benchmark scores were around the same.

    Undervolting did help (I undervolted on the stock paste too) and brought temps to just under 100, so it wasn't throttling as much, but still got hot. R20 score went to 2100+

    After getting (and returning) a Dell G5 SE, I went back to my G3, and decided to get some Kryonaut, after a discussion in the G5 SE thread.

    I just re-pasted with Kryonaut, and it surprised me how much it seems to have helped.

    In Cinebench I get around the same scores (2118 on last run) but the fans didn't come on at all until around 1/3 of the way through the test, when the CPU hit 88-89, then the fans kicked in (high performance mode in Dell Power Manager) and it reached 90, but quickly dropped to as low as 84, and tended to hover around 85-87 the entire time. Much lower than the 95-100 it was at before.

    All 4 cores at 4Ghz

    Sorry there's no "before" screenshots, but I didn't think to take anyway, since I still remembered how it was with stock/MX-4

    I almost destroyed my XPS 13 9350 with some chinese brand thermal paste. Granted, it was probably dried out, but after ordering some Krynoaut, temps are good!
    I did have to order a new battery, which well, it needed a new one anyways. Have you had a chance to try the liquid metal thermal paste?

    Nah I don't trust myself to apply it properly, wouldn't want to risk it.

    Just did a benchmark test in Sleeping Dogs on extreme settings.

    GPU maxes out at 69-70C

    CPU hits 70C max with turbo boost off, and 70-75C with turbo boost on

    Need to test GTA V or something else which will constantly run at 4Ghz

    ok. I read that liquid metal is brutal to apply, I guess I am going to give this a shot on my old acer. It's fans kick in alot. Maybe the paste on it is dried up to nothing. Thanks.

    You need to build up a kind of barrier around the die with electrical tape or normal thermal paste or something. I still worry that it might leak over the tape as the laptop moves around. Also liquid metal can eat destroy heatsinks if they'e aluminium

    If it's really old, could just be clogged fans as well. Use compressed air to blow the dust out (put something inside to stop the fans spinning so the bearing doesn't wear out).

    MX-4 might work really well for you as well, most people recommend it and it's cheaper per gram. It's just that Kryonaut seemed to help much more for me on the Dell

    I still used MX-4 on the GPU just because you get more per tube loll

    I have used Kryonaut with great success. Liquid Metal is amazing, in the right situation. It is however messy, conductive and ideal for a static application. Kryonaut is really good for most notebook applications.

    Are you saying with Kryonaut you need to build the dam?

    Kryonaut is a paste so no dam required. Liquid Metal requires extra care, for a notebook I personally recommend Kryonaut,
