I run a Derale cooler/fan combo in front of my fuel cell, just behind the rear axle. Bought new on ebay for $40 (they're about $130 normally). At the trans I found NPT to -6 adapters on Summit, and ran ATF rated line to the cooler. Wired the fan to kick on at same time as rad fan. Keeps my 9.5" converter cool!
