what i did for my build.... (not finished yet) is i relocated the usb ports (use a heat gun and cover the rest of the board w/ a couple layers of foil to avoid damage) and then i cut my heat sinks down and mounted some small fans (max 12v input and did the 12v fan mod on them) they are very quiet compaired to the stock xbox fans.... i plan to install a thermometer to avoid over heating but i thin i can keep it pretty cool and who hope this helps
