    Hi all, I'm new here so if the format of my post is bad, I apologize. Also, thank you in advance for reading my post.

    I have an hp dv4-1465dx laptop that overheats. I have gone through my first board already and am on my 2nd mobo (cheap CL find). This time I replaced the GPU heat-wax w/ a copper shim and drilled holes under my fan.

    My question:

    I want to mod my heatsink.

    The current macro shape of the heatsink is a C

    Since the heat has to go around the C to reach the radiator fins, I wanted to attach a shielded copper wire with Arctic Silver Thermal Adhesive from the CPU/GPU block to the other side of the fins to improve heat transfer.

    However,

    This would make the shape of the heatsink an O

    Is there any problem with "completing the loop?"

    I remember from my basic physics class that the transfer of heat/ e- would make create an EM field.

    Would this "circuit" damage my CPU/ GPU?

    Thanks again,
    I tried doing an extensive search but couldn't find anything on the specific topic.
    I did, however, find a few pictures of O shaped laptop heatsinks, such as for a sony laptop (Sony VGN-FJ170/B).

    A wire wouldn't improve anything. Yes in theory there will be less thermal resistance but that would be at most a fraction of a degree.
    If you'd add another heatpipe there could be improvements if the heatsink is capable to handle more heat.

    Again in theory. In practice the EM field produced by something like this wouldn't be detectable.

    Absolutely not. But a wire wouldn't improve anything anyway.

    The easiest way to improve cooling in a notebook is to lower the air flow resistance so that more air is moved over the heatsink.

    awesome, thank you for the reply!

    i had tried bending a heatpipe to join the two but was having issues fitting it and ended up breaking it :(

    thanks again

    DO NOT PLAY WITH HEATPIPES. it's extremely dangerous. you can get seriously burned.

    This, if you crimp one, pierce it, etc, your heatsink will perform even worse. Bending it could make it practically useless too.
