Cook the pasta in a large pot of salted boiling water until al dente. Drain and set aside to cool.
If using fresh corn, brush each ear with butter and grill until slightly charred, about 8-10 minutes. Slice the kernels off the cob. For frozen corn, heat in a skillet with butter until warmed through.
In a medium mixing bowl, combine mayonnaise, sour cream, lime juice, chili powder, cumin, salt, and pepper. Whisk until smooth. Add chipotle chilies if desired.
In a large mixing bowl, combine cooked pasta, corn, diced red onion, jalapeño, cilantro, and 3/4 of the Cotija cheese. Pour the dressing over and toss to combine.
Cover and chill in the refrigerator for at least 30 minutes to allow flavors to meld.
Before serving, give the salad a good toss, then top with remaining Cotija cheese and a squeeze of lime juice.
