So it is obvious that simply having the chip's heat radiate from the chip and relying on incidental convective cooling from airflow inside the case is sufficient. But that airflow is blocked in the enclosed confines of the I/O cover, although the heat will still flow upward through the top-right opening of the I/O cover. But that is great to know that the Aquantia chip throttles to save itself.

    I agree that the VRM water block is really not needed. But EK states that their X299 CPU-VRM monoblocks' redesigned cold plate cools the CPU 9 degrees-C *BETTER* than their CPU-only Supremacy EVO blocks. And that is the MAIN reason that I am still going to get the EK R6E monoblock, now that I know that we don't have to totally remove the lovely R6E I/O cover The additional better VRM cooling just adds extra tasty icing onto the monoblock cake.

    You're always welcome to contact ek and tell them about your requirements. Don't know if their reps look at these threads.

    As for whether a given chip should have a heatsink, it depends on numerous factors, including how much copper there is in the pcb and how much heat there is from surrounding components.

    I'm actually surprised there isn't a little fan under the I/O cover like there is in other x299 motherboards. Being that the chip is 'enclosed', and we don't want throttling/damage, as Raja would say it would be probably wise to consider cooling it in some manner. I wrote on the APex thread if the Apex has the same situation with the VRM and the 10G chip as I'm still up in the air as to which i'm gettting.

    The fan wasn't needed to meet tdp specs, so that's why there isn't one.

    Wow you learn something new.

    I found a few little heatsinks that advertise being able to dissipate that much heat and since it will be right at the back of the case with a fan right there bringing air into the case, I think it will be good should I go that route. Still up in the air about the Apex vs the RE6. Pros/cons with both.

    While we're on the subject of overclocking, the type of stuff you'll be doing with your choice of CPU hardly requires a VRM water block. With some airflow over R6E heatsink, you can pull well over 400W through the VRM before temps hit throttling point.
    To your point - with a 92mm fan placed as pictured - pushing ~400W through with totally reasonable VRM temps (though I plan to add an EK mono-block soon):

    EDIT: seen as much as 456W with 430-440W sustained and still ~75C VRM temps with the setup in the picture
