    Good afternoon fellow NBR members.

    I've seen a few threads that mentioned upgrading the P870KM1 with heatsink(s) from a TM model (if I recall correctly). I am running the laptop in my signature with 1080 GTX SLI and a 7700K.

    1. I have the vapor chamber GPU heatsink. Does the upgrade require me to replace both the GPU and CPU heatsinks?
    2. Are load temperatures reduced significantly enough to justify the cost/labor of the upgrade?
    3. If the upgrade is indeed worth the investment, could someone kindly point me to a guide/tutorial, if one exists?

    Regarding fan control on the P870KM1...I have long since removed Control Center because the fan control wasn't very precise. More often than not it would start the fans way too late, and sometimes not start the fans at all. Is there a good program for fan control out there yet?

    Any help is much appreciated.

    1. If your vapor chamber is the stock KM1 unit that has extra heatpipes going into the CPU heatsink, you will need to replace or modify it. As TM1 CPU heatsink has an extra radiator for the VRMs and will not fit together with KM1 vapor chamber unless modded. Mod is mentioned on the forums.

    @jc_denton Thank you for that information. 10-15° is a significant decrease in temperature.

    10-15c is from looking at the comparison between km1/tm1 heatsink here

    To go further you can pair it up with either a delid, custom ihs, liquid metal or a direct die vapor chamber mod.

    Thanks again. While we're on the subject, is there a modification for the KM1 GPU heatsink as well?

    Apart from having to cut the extra heatpipes in order to fit with the TM1, not as far as I know. Try asking in the P870KM1 owners lounge. :)

    The actual vapor chamber bit for the GPU is basically the same.

    I appreciate all of the help guys. I'm glad to hear that there's no need to replace the GPU vapor chamber.

    It's certainly a good heatsink :)

    Search my posts, I have made a very detailed workaround how to do it. It was worth doing it for sure, but I highly recomment buy a 4th fan (sepa) and connect to sata 3,3V port, which makes a big difference. GL
