    Hello everyone,
    I have a friend who has a Zenbook Flip UX370UA, and it does not run the best thermals (to put it politely). I proposed to try a repaste with Arctic MX-4. Has anyone repasted this laptop before? It looks different in that the heat sink looks like a massive copper slab that sits over half of the motherboard. Has anyone seen what it looks like under there? I have repasted laptops and delidded desktop CPUs before, but none of them ever looked like this. This difference is putting me off slightly. If anyone can chime in with some insight, I would very much appreciate it. Thanks!

    Final update: I opened the back cover of the laptop, went to unscrew the CPU heatsink and hit a completely stripped screw. It was so stripped and overtightened even cold welding a screw driver to it couldn't remove it. So this project came to a premature and terminal halt.

    It doesn't use heatpipes, its just a slab of cooper, under that slab, there will be thermal paste, and maybe some thermal pads, maybe buy a piece of 0.5mm thick Artic thermal pad(because its soft and better than what the OEM uses), and do a repaste like normal.

    But don't expect miracles, because how there are no heatpipes it will suck at removing heat from the cpu, maybe slap a giant thermal pad between that cooper slab and the bottom cover, but then the cover will be hot after prolonged use.

    Use TS to undervolt it as much as possible.

    Thanks for the reply! So the entire copper slab lifts up just like how regular heatsink pipes lift off of the CPU, and everything is the same as far as repasting goes? I'm repasting mostly to replace the factory stuff with MX-4; with a laptop like that, every degree helps.
    What is TS? I use Intel XTU for undervolting a 6700K, but I've never tried a laptop "U" processor before.

    Ah makes sense, I have heard of that before. I'm a lot more comfortable with XTU though. ;)
    I'll definitely record as much of it as possible, and post before and after results here.

    Believe me, I tried. It was breaking through cold weld designed to fix pipes, pliers stood no chance.
