I am running a finned cover! And those temps are with 75W140 full synthetic.
FWIW - At least since 2000 and maybe earlier, OEM diff fluid has been full synthetic. If you read the fine print in the service schedule, you'll see a note that says something along the lines of "if using conventional differential oil, service every 3,000 miles", while the OEM synthetic is supposedly good for life. Except for EMS vehicles, where they spec every 150,000. That's what I had always planned on, except I have history of breaking the rear diff every ~100,000. Now that I have the E450 rear axle under my van, I'm hoping it'll be my last!
One note on my diff temps.... I have the full Banks PowerPack, plus a tuner, so at hill-climb speeds my V10 should be making about 80 HP more than stock. You'd think I'd have lost a bunch now that I have over 454,000 miles but maybe not, since I can still smoke much lighter but stock V10s (and stock 6.0 and 6.4L Powerstrokes) in the mountains.
I have thought about an active diff cooler, but decided against the extra complexity. When I'm pulling the Cascades, it's not usually hot enough outside to be an issue. When it is, I don't hit 250F until I'm close to the top. 250F for short durations is fine, you just don't want to go much above than or hang out there too long. In the Rockies, most of the grades aren't as steep, and with the power loss from elevation, I've never seen it get as hot. The Sierras aren't as long of a climb. The only place I've have to pull over and let it cool, is westbound out of Death Valley.
