    This is great progress and goes to show how corporate greed is not stopping the innovation of enthusiasts.
    Keep it up!

    The EC would just need code changes.

    The cooling is a reference to how the 6 core CPU uses more power and the DM/DM3/KM were designed for 91W CPUs (6700K/7700K). Those CPUs just about never hit their base power limit at stock, and had no all-core turbo multiplier to soak up additional power headroom. You had to overclock (e.g. past 4.5 on both my 6700Ks) or run an artificial workload (prime95 FMA, IBT etc) to get ~90W consumption.

    Chuck in a 8700K, which the TDP spec says will use 95W at 3.7GHz, and then will add its 'up to' +600MHz all core turbo to soak up more, up to the +25% (~120W) turbo power headroom as soon as you throw a 100% load at it, things will quickly get toasty on those stock older heatsinks

    Ok but where on the motherboard is the EC and now are you going to cool it?

    1) "EC Mod" (firmware)
    and
    2) "Cooling" (for hungrier CPU)

    not "mod AND cooling for EC"

    OK then. I am assuming it's gonna need a beefier heatsink with more pipes?

    Yep. Just looking at the TM CPU heatsink, it has 4 pipes and the small 2nd grill (although without fan). But also, they are located under the main heatsink plate with only a thin shim for IHS contact, unlike prior P870 CPU HS where the heatpipes are on top of the main plate

    Also the whole fan shroud is copper

    This is an alternative kind of pipe ...

    well, the 4th pipe isn't even going to the main grill/fan anyway so a small pipe and grill might work? will probably need to mod a bit of the frame to fit but that's something i can handle maybe. LOL

    Would be interested in seeing how @Mr. Fox does his CPU heatsink.

    Is the fan shroud soldered to the radiator? If not a copper shroud is pointless.

    at the very least it should be soldered to the heatpipes judging from the picture...

    The 3rd main pipe are thicker vs. on the older HS as well.
