The good guys at Thermalright were nice enough to send their latest heatpipe heatsink, the Ultra 120 for all Intel P4 LGA775 processors, P4 Socket478 processors and AMD Athlon64 / FX / X2 / Opteron (all models) for a test spin. This unit features four heatpipes bent into a "U" shaped configuration. Note that the fins feature a bent winglet design to minimize airflow resistance.

What’s nice about this heatsink is that it uses a 120mm fan - noise levels can be more tolerable than high speed 80 and 92mm fans. The Ultra-120 is a logical progression from the Ultra-90. Note that this heatsink is fairly large - at 745 grams/1.6 pounds, this is not a light weight cooling solution and is on the large side as well (no such thing as a free lunch).
