You don't *need* to replace the stock mosfet cooler.

If you want to replace the NB cooler, just twist the NB cooler w/heatpipe and it will come loose from the mosfet cooler.
You may want to take everything off the board when you do this so you don't break anything :-)

BTW I have the Thermalright HR-09 but have *not* fitted it to the board as it is just a bit too short in my oppinion. It *just* covers the outer-most mosfets and since you can read that they don't run warm in this thread (and they don't) you might as well stick with the stock.

To be sure I removed the blue heatshield and put a near-silent 120mm fan close to both of them - no problems.

Really now...hmm...I'll give that a try tomorrow.

EDIT: Mind sharing how many volts you're running through the northbridge? I set it at 1.58v for my overclock (quad 475x9) and, based on touch since there doesn't seem to be a sensor for it, the northbridge feels pretty dang hot compared to my 4870X2, which idles at 50°C.
