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 !!
