Well should be ok.
If chipset gets too warm there is always the zalman heatsink, but beacuse of the design of the DFI ultra D if you have a large GPU, which im guessing you will have in a system like that you will need to bend back the fins to fit it in.
Also if you got some ram sinks stick one of the PWmic chip, its to the right of the DIMMs and just next to the ATX 24 pin socket. Thats what will heat up unless you have a fan on it when clocking.
