Need small, quiet HSF

[KoolAidKid]

I am putting together a Flex ATX system. One of my main priorities is reducing noise, and it's gotten to the point where the Intel retail HSF is the loudest part of the system. I would like to replace it, but there isn't a whole lot of room. I'm looking for a quiet HSF that is no more than 60 mm deep. The Zalmans are great for silence, not so great for size. Other relevant system specs:

Asus P4S333-M mainboard
Intel 1.6A currently running at 1.6, occasionally I crank it up to 2.4

Overclocking is not a prioirity. Any suggestions?

Have you looked at a Vantec Aeroflow? You can get one in either flavor for the CPU that you use.
