    I just learnt this is a thing. With a delidding tool it looks like a breeze. CPU's get up to 80° when fully used.

    So, should? Shouldn't I? Is this even possible or necessary in a P170EM?

    You can't. Mobile CPUs are bare die. No IHS to de-lid.

    I was too lazy to open up the lid to double check, but that explains the service manual image I was looking at. It's just that I read people talking about delidding in this forum so...

    Thanks for the info :)

    The people talking about de-lidding in this forum are referring to more recent Clevo models, some of which use desktop instead of mobile CPUs. Those model numbers generally start with P7 and P8.

    Yes all the HQ/HK/HQ/XM models are all bare die, only the desktop chips have lids to protect them from high pressure desktop heatsink mounts.

    If you want better temps try liquid metal. My P170EM with a badly fitting heatsink and conductonaut, with a 3720QM pushed as far as it can go (prema bios partial unlock no power limit) the hottest core stays under 80C stress tested on max fans.

    Wouldn't the LM spill without the lid? Or how do you prevent this spillage?

    The metal part of it forms an oxide 'skin' in contact with air. When the gap is small enough this is enough to hold it in place.

    If the gap is too large this may not be enough to hold it. But by far the biggest cause of spills out the side is using too much
