Aluminum Differential Cover Thermal Results

I think it's helpful to look at the big chunk of iron near the axle tube. That should be a good place to compare the two configurations since it's the same for both. For the baseline case, that's showing "white" or around 199F. For the aluminum cover case, it shows "deep red" or 151F."

I'm not buying - that's confirmation bias. Explain why the area where the axle tubes enter the diff (which has the most thermal mass) is essentially the same. Comparing the pictures, by far the biggest difference is the cover itself. And, if you think a cover is lowering the temperature by 48 degrees, want to buy a bridge?
