    Hi@All!

    I have a XPS15 L502X running with a 2860QM 3,5 Quadcore, 16GB Ram and a GTX1060 EGPU.
    My CPU is pasted right now with MX-4 2019 Edition, but i the temp under load can go over 90C°
    Now i am considering pasting with conductonaut.

    BUT two things:

    1.) The heatsink is copper but i'm not shure what silverish material is that around the copper plates ?
    Is it aluminium or plated copper or someting else ?

    2.) I read that in general it needs perfect heatsinks in oder to work with metallpaste. So did anybody tried to use conduconaut on a Dell Laptop with a similiar heatsink ?

    Please no warnings about metallpaste. I know the dangers and i know exactly how to apply it. I just want to know of other experiences with metal past on laptops and i wonder which material it is, because if its aluminium, then i may get some epoxy on the area around the copperplate.


    Here is how the heatsink looks like:

    I think you are heat soaking your heatsink, LM wont help you, given that there is only one small heatpipe.

    And its aluminium around the cooper plates, you need to "seal" it with varnish.

    Thank you senso for your answer!

    What do you mean with "heat soaking" ?
    Do you mean i used to much of the MX-4 ?
    i pasted it really thin with small scraper.

    What does LM mean ? Metallpaste ?
    Yeah i will seal it with surface epoxy resin, i think....

    I think they mean the limited heat pipes and radiator can only take on so much heat, and likely already absorbed as much heat as it possibly can (heat soak). If so, better thermal transfer won't help as the cooling system is already doing all it can do.

    Hm. I think i just have to try it out. :D
    I'm not shure about that heat soaking, because
    when the heat gets transfered to the heat sink more effectivly
    with metal paste the heat sink gets simply more hot than before
    so with the same fan speed more heat gets out of the Laptop, dont you think ?

    Likely best method is getting a faster fan in the same housing

    Check the colatge and amp and look for other fans, then if you find a faster fan you will likely have to software control it for max fan speen or cut the pwm wire (if you have one, probably do)

    Hi TheReciever
    What is colatge ?
    But it has to be exatly the same size... are there standards for this kind of fans or what ?

    They meant voltage. I can't answer on the fans, I am interested to know how standardized they are too. I wouldn't think they create custom fans on every laptop, maybe the higher end ones but wouldn't think all of them. However, that being said, I wonder how easy it is to get a faster RPM, or higher CFM fan in these exact sizes?
