Burning smell and small amount of smoke occurred during cruise phase of flight. Declared an emergency with ATC and requested direct to ZZZ1. Accomplished smoke removal checklist and made an overweight landing at ZZZ1. Emergency equipment inspected exterior of plane after landing and found no evidence of fire. Smoke and smell had dissipated inside the plane so we proceeded to the gate followed by emergency equipment. Maintenance told us that a recirculation fan had failed and had caused the problem.
