looks almost like the shuttle heatsink

The SB-2 has been arounf for a couple of months but it performs slightly worse than the XP-90.
The SI 97 is very interresting though as it looks like it's a Socket A version of the XP-90 which should make it the best Socket A heatsink. The XP-90 outperforms the SP-97/94 on other platforms so it should be the same on the Socket A

That SI-97 looks pretty cool. If it performs well enough I might pick it up to replace my current 500mg heatsink.

SB-2 look's like they tried to copy the Zalman concept,except their HS fins are spaced much closer than Zalman's and probably cant dissipate heat as well.(my assumption)
You'd need some pretty serious air flow to help dissipate that heat wich means more noise.
Also the closer proximity of the fins will promote dustball build-up sooner wich means your cooling efficiency decrease,noise increases and you're motivate to have to clean it out more often.
I just ordered the Zalman for my AMD64 3500 S939 and hope to achieve a bit better cooling than stock AMD HSF so that I may try a little bit of overclocking.I'm jsut hoping I made the right choice.
Theory and reality often produce unexpected results.
