I like the answer here. One guy glued a heatsink to the top of the
chipset block on the Premium.

In the first posting in this thread, "Akele" reports "the chipset
becomes too hot to touch" when the Premium is installed upside-down
in a Silverstone case.

Since some users claim to have a hot chipset, even when the board
is right side up, I would check the temperature immediately after
you install the board. If you cannot keep your fingers on it for
two seconds, without getting burned, then you'll need to retrofit
something to assist the cooling process. That could range from placing
an 80mm fan over top of the chipset, adding a heatsink to the
top of it, and so on.
One reason for the chipset to get hot, even when the board is upright,
is if the MOSFET heatsink is not receiving cooling air. For example,
if you use a water block on the processor, there will be no cooling
air spilling off the CPU fan to cool the MOSFET heatsink. The
heatpipe moves the heat from the chipset, up to the MOSFET sink.
You must have some air passing over the MOSFET sink, to properly
cool the thing.
The reason I am concerned about dealing with the Premium, is the
fact that the MOSFET heatsink and the chipset block are fastened
together. To "fix" the problem, you'll need to take care of the
MOSFET end of things as well, and there really aren't any retail
solutions you can slap on there. Maybe you could find some
aluminum heatsink stock somewhere, and cut a chunk to fit the
MOSFETs, but it won't be nearly as easy as using one of these
on the chipset.

The nice thing about the Deluxe, is the cooling solutions for
the chipset and the MOSFETs are independent of one another. If
the chipset fan starts to make noise, you can always put the
MCX159 on there, or use a Zalman heatsink.
