Tenmaxx Lasagna. Quiet and very good cooler to boot. it's small as well, so it don't take up any PCI slots. kinda pricy though, as expensibve as the blue orb that cools better and includes more "accesories". But the blorb is louder and takes up one PCI slot.
edit:heres a review of the
Tenmaxx Detonator (successor tot he lasagna).
BTW, its nicknamed the lasagna because of how the metal sheets are layered, kinda like lasagna.
