I finaly did it... i took all the crap out of my shuttle ( mobo included ) and took my dremel out and started carving... after i got the honey comb out i could tell the sunon stock fan was a little less noisy. then i took it apart again today and replace that jet engine/leaf blower sunon fan with a oh so quit panaflo and applied some artic silver 5 temps are down noise is down and i could not be happier. for every one who has a shuttle i would recommend this fan and a small tube of artic silver.. it makes a world of a diffrence. i cant even hear the computer. sad thing is i had the sunon runing at 5% and it is 10 times louder then the panaflo at 100%.
