Aluminum fins reminds me of a stock hsf more then anything. I'll still take the Zalman over the two others seen there especially the heigth seen as well as the black frame around the center one. When the tip of one blade was caught up in the array the temps read 107C for the cpu while the 9700 was the one that simply threw the heat away from cpu by the free air movement around all sides as well as the copper fins.
