I can either attach a heatsink to it (even though I have no clue as to how
to make it stick) or I can direct the airflow from a fan diretly on to it.
(I still have the fan from my old A590 harddrive, small and good airflow)

I know I know, I can do both, but I first like to know the effectiveness
differences between passive and active cooling...

What's next...cooling the capacitors??

I assume you mean cooling the programmable divider clock chip.
Definitely a heat sink required first rather than a fan, since you always
need surface area to carry away heat.
However, how about one of those earlier cpu integrated heatsinks with
imbedded fans? Could be the best if we could figure out how to attach it.
.
We need a firm but removable connection, and good thermal transfer. Anyone
had their case open recently to see how much space there is around the chip?

This brings up an interesting point. I have two computers that each have 3
double-sided DIMMs, 16 devices per DIMM. I've seen figures of 0.9 watts per
device (anandtech, quoted for SDRAM, in the Rambus analysis). That suggests
my RAM is drawing ~22 to 43 watts, depending on how you count an SDRAM
"device."

Are these realistic numbers? SDRAM is inherently well-suited for passive
cooling, but I was a little surprised to find it took power comparable to
(or greater than) my CPUs

Actually, once I put a small pentium HS/fan on the ICS chip I was able to
run my Coppermine 600e at 900 without any problems. Before I could only get
around 850 stable. So it does appear to help in some cases...your mileage
may vary.

I would guess that all you need is a heatsink.....just enough to take the
"edge" off this inferno of a chip.
