Overclocked Cafe has a look at Vantec's Iceberq Chipset/VGA cooler. This is an all copper cooler, that has a small enough footprint to fit almost any board.

My ongoing battle against the forces of evil (read that as heat) extend beyond just the CPU, chipsets are the next in line when it comes to heat aversely effecting performance of a system, and I have tried everything from cutting down socket 7 active coolers, peltier coolers (dismal failure) all the way down the gambit, for the most part the increases in cooling I have gotten have at best been minimal.
