    Hi guys I have an Dell Inspiron 7570, and i have repaste it(thermal grizzly kryonaut). The problem is that i have removed a component that was on the cpu(i think that was on the integrated GPU) and i have sobstituted It (the orange pad) with an After market thermal pad( from the photo you Will sede how the heatsink is designed)...
    The problem is that now the integrated GPU run Much hotter...
    I will put some photos so to understand better.
    I cannot inderstand why they have made an heatsink like that with a kind of little hole corresponding to the I-GPU that prevents from putting normal thermal paste.

    Have you checked the mounting and contact after you replaced the thermal pad? Maybe it's not sitting nicely in the cut out. Perhaps try sticking the pad inside its cut out when you reattach the heatsink since it would be more easily misaligned having it sitting on the die with the edges of the cut out coming down on it.

    Yes that is a weird way to design a heatsink... Necessitated by Intel's multi-die packaging.

    thank you for the suggestions, i have put in the cut offf a pad but it was too thik i think at this point... i will try to reopen and repaste again using a thinner pad (0.5 mm)

    I don't think a pad is a good idea.


    The inherent density and limit of compression will mess with the balance of the core contact.

    I recommend you either use K5 Pro, lots of thermal paste (I'm pretty sure this has the same thickness as the CPU silicon) or alternatively just leave it uncooled (some manufacturers do this).


    The smaller chip inside the CPU interposer is the chipset btw, not iGPU. The iGPU is inside the main silicon.

    sorry I was thinking... you mean lots of K5-pro or lots of any other thermal paste ?
    Just to know if you think a lot of normal thermal paste will do the trick.

    K5 Pro is much thicker than any other thermal paste, including the garbage-tier ICD.

    The chipset doesn't consume much energy, so it's fine to use K5 Pro that has a lower thermal conductivity.


    But I'm pretty sure that the chipset has the same height as the CPU silicon, so you can try a little thermal paste and see how it spreads (tighten heatsink for 5 minute and remove to observe).

    sure the chipset has the same height as the CPU silicon, the problem is the heatsink that with the cut-off it doesn't touch the chipset i think ... but i will surely give it a try ;)

    I can't see the pictures.

    Can you try imgur instead of that cancer website?

    You could consider fujipoly ultra extreme thermal pads. 17w/mk means they're roughly better than the thermal paste on your CPU.

    I've never heard of such performing thermal pads, they're pretty impressive.
    thank you for the advice i will keep them in mind.
