Hi Bob
Just wondering if you could fit a couple of 120 mm square computer case style cooling fans over the hottest part of the core. Usually 25 mm thick. The type designed to run from USB need 5 Volts DC at usually under 0.5 Amp each. You will need to chop off the USB plug. If you feel lucky, run them direct from the 6 to 7 volts of the battery, they will just go a bit faster. If you want to play safe, add a small series resistor to drop a volt or two and end up at about 5 volts.
Any kind of airflow is vastly better than none
Cheap enough for a try-out
