I had a via nano at 1200MHz that was just a lovely machine and ran with just a single silent system fan (no CPU fan even)
Same here! Only fan is on PSU but was small and quiet.
They are still licencing IP out (to China specifically IIRC)
Or even if they make - they can be purchased anymore. I have one Eden 600 or 900MHz CPU on Mini-ITX MB.
