This is my cooling solution. The fans are 240VAC run at 120VAC, blow downwards, and are effectively silent. They provide more than enough air movement to keep the radio cool even during AM operations with 50W average power. It does not take a lot of air to make a big difference and nearly any fan will work.

Here is an article discussing cooling of the 100D and 200D in some detail which you may find interesting: http://wu2o.dyndns.org/wu2o_fans.html
