If you want to passive cool a cpu, you need a cpu that can be passively cooled. This is pretty much only specific low powered cpu's like VIAs, or laptop model cpus. However many value cpus can be cooled with a giant heatsink and a giant slow moving fan. The key is you only need SOME airflow, you don't need massive airflow if you have enough surface area.
Thermalright makes a few (massive) coolers that are meant to be run without a fan.
Just don't expect decent temps OR any overclocking.
Not worth it at all IMHO. - processors get as hot as how hard you make them work.....with a duo, you could slow down the clock
- underclock it (?), to reduce heat...
A good low RPM 120mm fan will do wonders for a decent heat sink [with good thermal paste on] and will make very very little noise. e.g.

The only way you'd even hear it is if you had no other fans in your system.
The Core 2 Duo's work fine,(even moderately overclocked) with the Thermalright Ultra 120 extreme cooled passively. It does tend to get a little on the hot side,  though it definitely won't fit a 1u case.
I don't know of a cheap/small passive for the Core 2 Duo.....

Aitch :)
