I think the Sea Fury & some other tightly cowled Centaurus powered a/c
used fans. Didn't the Constellation use fans too?

I think the FW 190 installation was well studied. It was excellent. A few
of the Typhoon/Tempest dervatives also used Germanic style radiators a'la
FW190D series and also achieved a speed improvement.

The 490mph XP72 which was a P47 derivative had a fan.

The fw190 had a relatively compact, streamlined housing

The Skyraider also had the extra cooling fans, IIRC. But most of the
radial
engine applications after the war were for transport planes (which could
afford
to have larger cowlings), cropdusters (which could go without cowls) and
some
helicopters (which had different cooling systems).
