I suggest you go to http://www.febo.com/pipermail/time-nuts/  back a couple 
of years and you will find every thing you ever want to know about  the FE 
5680A. Similar to the recent Lucent activity

I do realize that, but how big?  Normally "the bigger the better" is
not an unreasonable rule on heatsinks,  but I have heard that cooling
these too much is bad. I have here a heatsink  about 600 x 300 x 150
mm, although I think that is a bit OTT  !!
