    it’s plenty bright, even under normal room light condition, they are easily visible.

    I bet flattening these heatpipes on the CPU would help temps. I'm not sure why Clevo didn't do that and only installed flat heatpipes on top of the GPU.

    They must have come to the conclusion more on top of the die is better than flat. The pipes take up about 50% more width flat.

    It's very strange that the GPU temps are much lower than the CPU temps though during stress tests. Clearly the CPU fan has significantly more cooling potential than the GPU fan. Just look at the size of that thing!

    It could just be because of the thermal densities of the processor dies, but something smells fishy. Surely CPU temps should be much lower than they are.

    Given the GPU temps, this laptop should be able to cool cards with desktop level TDP with no problem. That may be a hint of things to come ;). Just speculation though.

    jc_denton BGA? What a shame.

    That's because of how they designed the heatsink, copper block on the CPU and vapor chamber for the GPU. Once GPU becomes saturated, excess heat bleeds into the CPU.

    Flat heatpipes cover a much higher contact surface than regular round HPs, allowing for more efficient heat transfer.

    But flat heatpipes are less efficient that round ones.

    This is true, but the perf reduction depends on heatpipe thickness and how much it is flattened. I assume the X170 pipes are sintered, since P870 also used them and they are cost effective.

    I’m just curious if anyone here is looking at this heat sink and thinking of ways to mod it to add some more efficiency to it? While I’m definitely waiting to see it with my own eyes before I pass any judgement on its cooling, I’m not against improving it. :D

    Just have to remove undercase and add a big watercooling XD
    I'm kidding I don't know a lot in cooling ^^'

    A while back I wrote about my speculations and worries about the X170 socket orientation and how it will affect the thermal performance.
