Overclockers Workbench heeft het PII-620 artikel geupdate met info over een aantal heatsinks. Hier een stuk over de extreem wrede Alpha heatsink (check deze pics bij HardOCP):
Ah, now this is a heatsink! This monstrosity is the mother of all heatsinks. Each fin is a full 38mm in length and shaped like an airplane wing for maximum airflow efficiency. The base is a tremendous 7mm thick, able to transmit heat away from the hottest of processors. The aluminum is soft, perhaps even softer than the VEK-12's, however it seems to stick to the drill bit, making it rather difficult to drill. The design allows you to quite easily screw in a 92x25mm fan using 4 long wood screws (such as you would use with any heatsink/fan). This gives you more CFM's of air than any heatsink/fan combination on the market, including all the 3 fan models, at a QUIETER db. The 44cfm model I'm using makes 34db of noise, but there's a louder one that blows 50cfm's.
