I have a 9600pro(350 core) with a vga silencer rev2 that I modified and removed the fan and duct in favor of a custom duct that pulls air in the side of the case and exhausts it out the back. With some minor volt mods and 1.6v through the mobo I have had ti clocked as hich as 550/800 with separate passive ramsinks that are only 1/8" tall. Get a VGA Silnecer!
