Thanks for the help.
I bought the adapter on eBay for $30, half of the retail price from Powerleap. But of course, it didn't come with the fan/heatsink so thinking back I probably should have just bought the kit from the manufacturer, now that I have to spend some more to complete the upgrade.
In any event, I am where I am so my next move is to buy a decent fan/heatsink combo. I'll probably get one of the Zalman or Spire units. I appreciate the advice.
