Agreed. I've found that fanless is much harder/hotter than I thought.
Even an undervolted fan blowing a mere whisper of air cools much
better than passive. For example, I replaced the noisy heatsink/fan on
my card with a passive northbridge cooler and aimed a 40mm fan running
at 5 volts at it. It keeps my GPU temps around 70°C in a
poorly-ventilated Mini-ITX case.

These chips are specc'ed to like 90-100°C so I'm not even on the
ragged edge of the limit, thanks to one nearly silent fan.
