Coolest running Socket 478 proc

[riclewis]

Just picked up a couple old Supermicro servers: (http://www.supermicro.com/products/system/1U/5013/SYS-5013C-T.cfm)

I'm going to use one as a router (pfsense) and one as a NAS (FreeNAS).

Neither of these applications should take a lot of power, so I'm interested in using the system in the coolest, most efficient, and most stable configuration I can. I want these things to run for 20 years.

What socket 478 CPU gives me the best shot at this situation? Should I downclock an existing processor? Does the FSB play a part in heat/power and should I run it slow (400 mhz).

Probably one of the socket 478 celeron CPU's that you can find here http://en.wikipedia.org/wiki/List_of_Intel_Celeron_microprocessors have the lowest tdp.
