I have the Volcano 6cu+ or whatever, the V6 with the copper insert. Its cheese, but I adjusted the positioning of the main fan (which is decent, not enough cfm), and stuck another fanon the opposite end... get temps in the low 40's, high 30's... which is damned good, but that's ****, compared to other more cost effective stuff out there... this sink should be cooling my f'n northbridge... *cynical laugh*
